Evidence at a Glance

Hip arthroscopy is the most coding-constrained procedure in this library. Where other families rely on NCCI edits and society guidance to define bundling, hip arthroscopy carries explicit parenthetical prohibitions inside CPT® itself. Two of the three femoroacetabular impingement codes cannot be reported together under any circumstance, and a distinct-service modifier will not change that. Separately, diagnosis coding is genuinely unsettled: ICD-10-CM has no single dedicated code for femoroacetabular impingement, and the coding content circulating on this topic is unusually unreliable.

Domain	Summary
Medicare NCD	No National Coverage Determination specific to hip arthroscopy. General "reasonable and necessary" standard applies (Social Security Act 1862(a)(1)(A)).
Medicare LCD / MAC	No dedicated national LCD. Traditional fee-for-service Medicare does not require prior authorization; medical review applies. Hip arthroscopy for FAI is uncommon in the traditional Medicare population.

Domain	Summary
Commercial coverage	Covered for appropriately selected femoroacetabular impingement syndrome and labral pathology without significant osteoarthritis. Managed via eviCore CMM-314, Carelon Joint Surgery, Cohere, Evolent/NIA, and TurningPoint.
Prior authorization	Required by most commercial plans and Medicare Advantage. Hip arthroscopy is among the more actively managed MSK procedures.
Coding constraint	CPT® parentheticals prohibit reporting 29916 with 29915, 29862, or 29863, and prohibit reporting 29914 or 29915 with 29862 or 29863. Capsular closure is included and not separately reportable.
Evidence level	Supportive for arthroscopic management of femoroacetabular impingement syndrome in appropriately selected patients. Outcomes deteriorate substantially where established osteoarthritis is present, which is why payer criteria concentrate on joint space and arthritis grade.
Imaging	Radiographs establishing joint space and arthritis grade plus MRI or MR arthrography characterizing labral and chondral pathology and confirming cam or pincer morphology.
Conservative therapy	Documented, dated non-operative care including hip-specific physical therapy is expected.
Diagnosis coding	There is no single ICD-10-CM code for femoroacetabular impingement. Coding practice combines codes from several families, and published coding content on this topic frequently contains outright errors.
Key documentation	Impingement examination findings, cam or pincer morphology on imaging, labral and chondral findings, joint space and arthritis grade, and dated conservative care.
Typical approval driver	Imaging-confirmed cam or pincer morphology with concordant impingement signs and preserved joint space, after documented conservative care. Denials cluster around established arthritis and insufficient conservative care.

Overview

Hip arthroscopy accesses the hip joint through small portals, typically with traction, to treat intra-articular pathology. The dominant contemporary indication is femoroacetabular impingement syndrome — abnormal contact between the proximal femur and the acetabular rim — together with the labral and chondral damage it produces.

Two morphologies drive the procedure. A cam lesion is an aspherical prominence at the femoral head-neck junction, addressed by femoroplasty. A pincer lesion is acetabular over-coverage, addressed by acetabuloplasty. Many patients have mixed morphology. The labrum is commonly torn and is repaired, debrided, or in selected cases reconstructed.

The rule that governs this entire code family

CPT® itself carries explicit parenthetical instructions here — this is not merely an NCCI edit. 29916 (labral repair) may not be reported with 29915 (acetabuloplasty), 29862, or 29863. 29914 (femoroplasty) and 29915 may not be reported with 29862 or 29863. Where both a labral repair and an acetabuloplasty are performed, it is one code or the other — not both — and a distinct-service modifier will not unbundle them.

Capsular closure is included in these procedures and is not separately reportable. Acetabular chondroplasty is likewise inclusive. The workhorse valid combination is 29914 with 29916 — femoroplasty plus labral repair.

Relevant Anatomy (High-Level Overview)

Femoral head and neck: a cam lesion is an aspherical prominence at the head-neck junction that levers into the acetabulum during flexion and internal rotation.

Acetabulum: a pincer lesion is focal or global over-coverage of the acetabular rim, producing direct impingement against the femoral neck.

Acetabular labrum: a fibrocartilaginous rim that deepens the socket and maintains the suction seal. Impingement damages it first, which is why labral pathology and FAI travel together.

Articular cartilage: chondral delamination at the acetabular rim is characteristic of cam impingement and is a marker of disease progression.

Hip capsule and iliofemoral ligament: divided for access and closed at the end of the case. Capsular management matters clinically but generates no separate code.

Joint space and arthritis grade: the decisive selection variable. Established arthritis predicts poor arthroscopic outcomes and drives payer criteria.

Peritrochanteric space: the extra-articular compartment containing the gluteus medius and minimus tendons and the iliotibial band — the site of procedures that frequently lack dedicated codes.

Clinical Indications

Femoroacetabular impingement syndrome — concordant symptoms, positive impingement examination findings, and imaging-confirmed cam or pincer morphology — refractory to non-operative care.

Symptomatic acetabular labral tear with mechanical symptoms and concordant imaging.

Symptomatic loose or foreign body within the hip joint.

Pathologic synovial disease requiring synovectomy, including synovial chondromatosis and inflammatory synovitis.

Symptomatic chondral lesions amenable to arthroscopic treatment.

Septic arthritis of the hip requiring arthroscopic irrigation and debridement.

Selected extra-articular conditions including peritrochanteric space disorders and gluteal tendon pathology — noting that several of these lack dedicated codes.

Note: hip arthroscopy in the presence of established osteoarthritis is where outcomes are poorest and payer scrutiny is highest.

Patient Selection

Variable	Why it matters operationally
Joint space and arthritis grade	The decisive variable. Payer criteria commonly apply a minimum joint space and a maximum arthritis grade; established arthritis converts an arthroscopy request into an arthroplasty conversation.
Concordant examination findings	Impingement testing — flexion, adduction, and internal rotation — reproducing the patient's symptoms. Imaging morphology without concordant symptoms is not an indication.
Cam or pincer morphology confirmed	Radiographic and cross-sectional imaging confirmation of the specific morphology to be addressed, matched to the planned procedure.
Labral and chondral findings	MRI or MR arthrography characterization supporting repair versus debridement versus reconstruction.
Conservative care completed	Dated hip-specific physical therapy and activity modification with documented outcome.
Age and activity demand	Younger, higher-demand patients without arthritis have the strongest indication; increasing age with degenerative change weakens it substantially.
Dysplasia assessment	Acetabular under-coverage changes the operative plan and may direct the patient toward a bone-preserving osteotomy rather than arthroscopy.

Contraindications

Active infection outside the joint, or medical instability precluding safe anesthesia.

Established osteoarthritis of the hip beyond the thresholds applied in payer criteria — both a clinical contraindication and the most predictable denial.

Significant acetabular dysplasia, where arthroscopic rim resection may worsen instability and an osteotomy pathway may be more appropriate.

Imaging morphology without concordant symptoms or examination findings — cam morphology is common in asymptomatic populations and is not by itself an indication.

Advanced chondral loss where arthroscopic treatment will not alter the natural history.

Inability or unwillingness to complete the extended post-operative rehabilitation and weight-bearing restrictions.

Conservative Treatment Requirements

Element	What payers look for
Duration	A documented, dated non-operative trial. Requirements vary by vendor and plan; capture start and end dates rather than a general assertion.
Physical therapy	A hip-specific program addressing core and hip abductor strengthening, movement retraining, and range-of-motion limits, with dates and functional response.
Activity modification	Documented restriction of provocative positions — deep flexion, prolonged sitting, pivoting — and the functional impact.
Pharmacologic care	NSAIDs or analgesics as tolerated, with joint-conservation counseling now referenced in 2026 UM policy language.
Intra-articular injection	A diagnostic or therapeutic intra-articular hip injection with documented response is frequently expected and is unusually valuable here, because a positive response helps confirm the hip as the pain generator.
Recognized exceptions	Septic arthritis, symptomatic loose body causing mechanical block, and acute traumatic injury are not subject to the elective conservative-care pathway. Label such requests explicitly.
Documented failure	State that conservative care was completed and describe the persistent symptoms and functional deficit.
PA Insight: the diagnostic injection carries unusual weight Hip, groin, and lumbar pathology overlap clinically, and reviewers know it. A documented intra-articular hip injection producing meaningful temporary relief does two things at once: it satisfies a conservative-care element, and it localizes the pain generator to the hip joint. Where the clinical picture is at all ambiguous, this single documented data point strengthens the request more than an additional month of therapy notes.

Imaging Requirements

Radiographs including an anteroposterior pelvis and a lateral view of the proximal femur, establishing joint space, arthritis grade, cam morphology, acetabular coverage, and dysplasia. Joint space and arthritis grade are what the criteria are written around and should be quoted.

MRI or MR arthrography characterizing labral pathology, chondral damage, and the extent of morphologic abnormality. MR arthrography improves sensitivity for labral tears.

CT where detailed osseous morphology or three-dimensional planning is required.

Where dysplasia or borderline coverage is present, document the coverage measurements, since they change the operative plan and may redirect the case.

The request should quote both: the sentence establishing preserved joint space and limited arthritis, and the sentence confirming the specific morphology to be addressed.

Medical Necessity

Pillar	Documentation that demonstrates it
Concordant symptoms	Groin or hip pain reproduced by provocative testing, with functional impact on sitting, pivoting, and activity.
Morphology confirmed	Imaging describing cam or pincer morphology, quoted, and matched to the planned procedure.
Preserved joint	Radiographic joint space and arthritis grade within the thresholds applied by the payer's criteria.
Intra-articular pathology	Labral and chondral findings on MRI or MR arthrography.
Conservative care	Dated trial with outcome, ideally including an intra-articular injection response.
Pain generator localized	Exclusion or evaluation of lumbar spine, hernia, and other overlapping sources.

Medicare Coverage

No NCD and no dedicated national LCD govern hip arthroscopy; coverage rests on the general reasonable-and-necessary standard with MAC medical review.

Traditional Medicare requires no prior authorization for hip arthroscopy, and it is not part of the Hospital Outpatient Department prior-authorization program.

Medicare Advantage plans routinely require prior authorization and commonly delegate to eviCore, Carelon, Cohere, Evolent/NIA, or TurningPoint.

Population note: hip arthroscopy for femoroacetabular impingement is uncommon in the traditional Medicare population, where degenerative change is typically established. Requests in this population should anticipate close scrutiny of joint space and arthritis grade.

Post-payment exposure concentrates on reporting code combinations that CPT® parentheticals prohibit — a documentation-independent error that no modifier will cure.

Commercial Payer Comparison

Payer / vendor	How hip arthroscopy is managed (summary)
eviCore by Evernorth	CMM-314 (Hip Surgery — Arthroscopic and Open Procedures) is the governing guideline; hip arthroplasty runs separately under CMM-313. The Cigna commercial edition carries an effective date of 08/04/2026.
Carelon Medical Benefits Mgmt	Joint Surgery guideline and Musculoskeletal Program code list carry the hip arthroscopy family.
Cohere Health	MSK surgical authorization platform used by several plans including Humana lines; morphology confirmation, joint space, and conservative care are the determinative fields.
Evolent / NIA	Hip Arthroscopy clinical guideline NIA CG 314, which defines discrete code groups: _ _ Femoroacetabular Impingement (FAI) Hip Surgery as 29914, 29915, and 29916; and Hip Surgery — Other as 29860, 29861, 29862, and 29863. A UM matrix governs allowable billed groupings. Note this differs from the hip arthroplasty guideline number.
TurningPoint	Delegated surgical PA on many plans. Its 2026 MSK policy updates addressed femoroacetabular impingement syndrome and both intra-articular and extra-articular arthroscopic and open hip surgery presentations — confirming that the extra-articular procedures are reviewed on their own criteria.
UnitedHealthcare / Aetna / Cigna / Humana	Each maintains hip surgery policy or delegates; Cigna managed lines run through eviCore CMM-314. Several plans maintain specific policies on hip arthroscopy for FAI.
Blue Cross Blue Shield plans	Vary by licensee; delegation may run to Carelon, eviCore, TurningPoint, or HealthHelp. Verify per plan, per cycle.
Payer guideline currency eviCore's February 2026 policy update records that CMM-314 was revised with no clinically impactful changes in that cycle, alongside CMM-312 and CMM-318. By contrast CMM-313 (Hip Replacement/Arthroplasty), CMM-311 (Knee Replacement), and CMM-315 (Shoulder Surgery) were revised with clinical changes that LIMIT coverage, effective 03/07/2026. Practices performing both hip preservation and hip arthroplasty should note that the arthroplasty guideline tightened even though the arthroscopic guideline did not. The Cigna commercial editions carry an effective date of 08/04/2026. Confirm the version in force at the time of service.

Prior Authorization Workflow

1. Eligibility & vendor identification. Confirm the vendor and the guideline version in force.

2. Confirm the pain generator is the hip. Document impingement testing and, where available, an intra-articular injection response.

3. Quote the radiographic findings establishing joint space and arthritis grade — the threshold criteria.

4. Quote the morphology finding confirming cam or pincer pathology matched to the planned procedure.

5. Compile dated conservative care with outcomes, or state a recognized exception.

6. Map the anticipated codes against the CPT® parentheticals before submission. Requesting a combination that CPT® prohibits signals a coding problem to the reviewer.

7. Flag any planned extra-articular or reconstruction procedure — labral reconstruction and peritrochanteric procedures may lack dedicated codes and may be reviewed on separate criteria.

8. Submit, track, confirm. Record authorization number, approved codes, and validity window; align facility and anesthesia authorization.

Documentation Requirements

Symptom character, duration, and functional impact (sitting tolerance, pivoting, activity limitation)

Impingement examination findings, including provocative testing reproducing the symptoms

Range of motion, particularly flexion and internal rotation

Radiographic findings quoted: joint space, arthritis grade, cam or pincer morphology, acetabular coverage

MRI or MR arthrography findings: labral pathology, chondral damage, morphology

Intra-articular injection performed and the documented response, where available

Evaluation or exclusion of lumbar spine, hernia, and other overlapping pain sources

Dated conservative treatment history with documented outcome, OR a stated exception

Assessment for dysplasia or borderline acetabular coverage

Planned procedures and the anticipated code combination, checked against CPT® parentheticals

Laterality clearly documented

Prior ipsilateral hip surgery, if any

Common Prior Authorization Denials

Denial reason	Root cause / prevention
Established osteoarthritis	Joint space or arthritis grade beyond the criteria threshold. Prevention: quote the radiographic findings early; where arthritis is established, reconsider whether arthroscopy is the right procedure.
Morphology not confirmed	Request asserts impingement without imaging confirmation of cam or pincer morphology. Prevention: quote the imaging sentence.
Symptoms not concordant	Imaging morphology without matching examination findings. Cam morphology is common in asymptomatic hips. Prevention: document provocative testing reproducing the symptoms.
Insufficient conservative care	Undated or absent hip-specific therapy. Prevention: dated entries with outcomes, plus injection response where available.
Pain generator not localized	Overlapping lumbar or groin pathology unaddressed. Prevention: document the evaluation and, ideally, the injection response.
Prohibited code combination requested	29915 and 29916 requested together, or 29862/29863 with an FAI code. Prevention: map codes against the CPT parentheticals before submission.
Extra-articular procedure not authorized	Peritrochanteric or gluteal tendon work performed but never requested. Prevention: identify and justify separately.

Denial reason	Root cause / prevention
Dysplasia unaddressed	Borderline coverage not discussed where rim resection is planned. Prevention: document coverage measurements and the operative rationale.

Appeal Strategies

Answer the specific criterion cited; hip arthroscopy criteria are itemized and respond well to point-by-point rebuttal.

For arthritis-threshold denials, supply the full radiology report with joint space measurements. Where arthritis genuinely exceeds the threshold, the productive response is a revised plan rather than an appeal — the evidence supports the payer here.

For concordance denials, supply the provocative examination findings and the intra-articular injection response.

For morphology denials, quote the specific imaging sentence describing the cam or pincer lesion.

Do not appeal a prohibited code combination. Where CPT® itself instructs that two codes may not be reported together, the denial is correct and a distinct-service modifier will not change it. Re-map the claim instead.

For extra-articular denials, recognize these procedures are reviewed on separate criteria and may lack dedicated codes; submit with operative rationale and a comparison code.

Preserve internal and external appeal deadlines; medical-necessity disputes qualify for independent external review.

Coding & Billing Overview

Operational overview for authorization and revenue-cycle teams. Descriptors and parenthetical instructions verified against CPT® and CPT® Assistant guidance, and against published specialty-society coding material. Detailed reimbursement methodology belongs in the GoHealthcare Revenue Cycle Knowledge Center.

Hip Arthroscopy Code Family (verified descriptors)

CPT®	Descriptor	Operational notes
29860	Arthroscopy, hip, diagnostic with or without synovial biopsy (separate procedure)	"Separate procedure" designation — not reported alongside a surgical hip arthroscopy.
29861	Arthroscopy, hip, surgical; with removal of loose body or foreign body
29862	Arthroscopy, hip, surgical; with debridement/shaving of articular cartilage (chondroplasty), abrasion arthroplasty, and/or resection of labrum	The labral DEBRIDEMENT/resection code, distinct from repair. Prohibited with 29914, 29915, and 29916.
29863	Arthroscopy, hip, surgical; with synovectomy	Prohibited with 29914, 29915, and 29916.
29914	Arthroscopy, hip, surgical; with femoroplasty (ie, treatment of cam lesion)	The cam-lesion code. Introduced specifically for femoroacetabular impingement.
29915	Arthroscopy, hip, surgical; with acetabuloplasty (ie, treatment of pincer lesion)	The pincer-lesion code. May NOT be reported with 29916.
29916	Arthroscopy, hip, surgical; with labral repair	The labral REPAIR code. May NOT be reported with 29915, 29862, or 29863.
29999	Unlisted procedure, arthroscopy	Applies to arthroscopic hip procedures without a dedicated code, including labral RECONSTRUCTION (as distinct from repair).
27299	Unlisted procedure, pelvis or hip joint	The open counterpart. Applies to open hip preservation procedures including periacetabular osteotomy, for which no dedicated code exists.

The parenthetical matrix — commit this to the workflow

CPT® instructs: do not report 29916 in conjunction with 29915, 29862, or 29863; and do not report 29914 or 29915 in conjunction with 29862 or 29863.

In practice this means: where both a labral repair and an acetabuloplasty are performed, report one or the other — not both. Published specialty guidance is explicit that the choice follows the principal intent of the operation. Debridement (29862) and synovectomy (29863) are absorbed into any of the three FAI codes. Capsular closure and acetabular chondroplasty are included and never separately reportable.

Modifier 59 will not unbundle these pairs. This is a CPT® instruction, not merely an edit with a bypass indicator. A claim reporting 29915 with 29916 is incorrect regardless of documentation.

Reportable Combination Matrix

Published professional coding guidance renders the parentheticals as a combination grid. Read down the left column and across the top: Yes means the pair may be reported together; No means it may not.

With →	29914 femoroplasty	29915 acetabuloplasty	29916 labral repair
29914 femoroplasty	--	Yes	Yes
29915 acetabuloplasty	Yes	--	No
29916 labral repair	Yes	No	--
29862 debridement	No	No	No
29863 synovectomy	No	No	No

The only prohibited pair among the three FAI codes is 29915 with 29916. Both 29862 and 29863 are prohibited with all three. Note also that NCCI Policy Manual Chapter IV states that, with the exception of the knee joint, arthroscopic debridement should not be reported separately with a surgical arthroscopy procedure performed on the same joint at the same encounter — reinforcing the CPT® instruction from a second direction.

Valid and Invalid Combinations

Scenario	Reporting
Femoroplasty + labral repair	29914 + 29916. The most common valid FAI combination.
Femoroplasty + acetabuloplasty + labral repair	29914 plus EITHER 29915 OR 29916 — not both. Select per the principal intent of the operation and document accordingly.
Labral repair + acetabular chondroplasty	29916 only. Chondroplasty is inclusive.
Any FAI code + debridement or synovectomy	The FAI code only. 29862 and 29863 are prohibited with 29914, 29915, and 29916.
Labral debridement without repair	29862, where no FAI code applies.
Labral reconstruction (not repair)	29999, with operative report and comparison code.
Diagnostic arthroscopy + surgical arthroscopy	Surgical code only; 29860 is a "separate procedure."
Capsular closure	Not separately reportable under any circumstance.
Currency warning NCCI procedure-to-procedure edits and modifier indicators are republished quarterly, and a modifier indicator of 0 means no documentation will unlock separate payment. Verify the active CMS edit files rather than relying on cached tables or vendor coding guides. Note that in this family the CPT® parentheticals are the more restrictive constraint and apply to all payers, not only those following NCCI.

Procedures Lacking Dedicated Codes

Labral reconstruction using graft, as distinct from repair — reported as 29999 with an operative report and comparison code.

Open hip preservation procedures including periacetabular osteotomy — reported as 27299, with published guidance suggesting comparison to established osteotomy codes.

Named arthroscopic hip procedures lacking dedicated codes, per published professional coding guidance, include iliopsoas tendon release, gluteus repair, trochanteric bursectomy, piriformis release, quadratus femoris release, and arthroscopic fixation of a bone fragment with screws. Ischiofemoral and subspine impingement procedures likewise lack recognized codes. These commonly require an unlisted-code pathway and frequently an appeal.

Open osteochondroplasty and open labral repair — no dedicated codes; 27299 with 29914 and 29916 referenced as comparison codes.

In every case, identify these pre-service. An unlisted-code claim submitted without pre-service discussion is materially harder to resolve.

Diagnosis Coding — Genuinely Unsettled

ICD-10-CM contains no single dedicated code for femoroacetabular impingement. Coding practice therefore combines codes from several families, and the published content on this topic is unusually unreliable — in preparing this guide we encountered widely circulated sources that cited a rotator cuff repair code for a hip labral tear and a recurrent-dislocation code for femoroacetabular impingement. Verify against primary sources and the AHA Coding Clinic, which has addressed femoroacetabular impingement with labral tear directly.

ICD-10-CM family	Description	Coding note
M24.851 / M24.852	Other specific joint derangements of right / left hip, not elsewhere classified	Verified billable. Commonly used where a more specific code does not exist; M24.859 for unspecified hip.
M24.151 / M24.152	Other articular cartilage disorders, right / left hip	For documented chondral pathology of the hip; M24.159 unspecified.
M25.851 / M25.852	Other specified joint disorders, right / left hip	Used in published research to identify femoroacetabular impingement cohorts; confirm against payer preference.
S73.19- family	Other sprain of hip	The traumatic family, with laterality and a 7th character (A initial, D subsequent, S sequela). Applied to traumatic labral injury.
M16.- family	Osteoarthritis of hip	Where degenerative change is documented. Its extent is the decisive selection variable and should be coded accurately rather than omitted.
M25.551 / M25.552	Pain in right / left hip	Non-specific; never the sole support for arthroscopy.

Operational recommendation: because no single code exists, adopt a documented organizational convention for femoroacetabular impingement coding, validated with your major payers, rather than leaving it to individual coder judgment. Inconsistent diagnosis coding across a surgeon's FAI cases is itself an audit signal.

Modifiers and Place of Service

Item	Guidance
RT / LT	Laterality; append per payer requirement.
59 / X{EPSU}	Distinct procedural service. CAUTION: will NOT unbundle the CPT®-prohibited pairs in this family.
51	Multiple procedures, where the payer requires it for valid concurrent codes such as 29914 with 29916.
22	Increased procedural services; requires substantial operative-note support.
AS / 80 / 81 / 82	Assistant-at-surgery, when documented and supported.
POS 24 / 22	ASC and on-campus hospital outpatient are the standard settings.

Implants, Devices, and System Considerations

Suture anchors for labral repair from Arthrex, Smith+Nephew, Stryker, ConMed, and Zimmer Biomet. CPT® reflects the repair, not the anchor.

Knotless and all-suture anchors are widely used; document the construct to support the reported repair.

Labral reconstruction grafts — iliotibial band autograft, allograft tendon — carry both an unlisted-code burden and a coverage question. Verify pre-service.

Traction systems and post-less positioners are technique variables that do not change coding.

Capsular closure devices support a step that is explicitly inclusive and never separately reportable.

Physician professional coding does not separately report implants; facility implant reporting follows facility contracts and reporting rules.

For any novel implant or graft technology, verify FDA status, coding, and payer coverage as three independent determinations.

GoHealthcare Clinical Insights

Operational recommendations from MSK authorization practice

Build the CPT® parenthetical matrix into your coding workflow as a hard rule, not a guideline. It applies to every payer.

Require the operative note to state the principal intent where both acetabuloplasty and labral repair are performed — that single sentence determines which code is reportable.

Quote radiographic joint space and arthritis grade in every request; these are the threshold criteria.

Document a diagnostic intra-articular injection response wherever the clinical picture is ambiguous. It localizes the pain generator and strengthens the request disproportionately.

Adopt a documented organizational convention for FAI diagnosis coding, since no single code exists.

Flag labral reconstruction, open preservation procedures, and peritrochanteric work pre-service — these lack dedicated codes.

Treat established arthritis as a redirect rather than an appeal target; the evidence supports the payer position here.

GoHealthcare Leadership Perspective

Executive view: a procedure constrained by the code set itself

Most procedures in this library are constrained by payer criteria that vary, evolve, and can be argued. Hip arthroscopy is different. Its principal constraints are written into CPT® as parenthetical instructions that apply to every payer, cannot be modified away, and are not subject to appeal. A practice performing femoroplasty, acetabuloplasty, and labral repair in the same operation cannot report all three, regardless of how much work was performed or how well it was documented.

This has two implications for service-line leadership. First, the coding workflow must encode these rules as hard constraints, because a claim reporting a prohibited pair is incorrect on its face and represents compliance exposure rather than a reimbursement opportunity. Second, because the code set does not capture the full work of a complex hip preservation case, the operative note becomes the only durable record of what was actually done — which matters for outcomes analysis, revision planning, and any future code-set revision. Practices building a hip preservation program should invest in structured operative documentation from the outset rather than retrofitting it later.

GoHealthcare Prior Authorization Insight

What we see that payer policies do not spell out

29915 and 29916 are mutually exclusive. Not a soft edit — a CPT® instruction. Choose by principal intent and document it.

Debridement and synovectomy vanish into the FAI codes. 29862 and 29863 are prohibited with 29914, 29915, and 29916.

Capsular closure is never separately reportable. Neither is acetabular chondroplasty.

Joint space is the threshold. Established arthritis is where hip arthroscopy outcomes fall off, and criteria are written accordingly.

Cam morphology is common in asymptomatic hips. Imaging alone is not an indication; concordance is.

The injection response is underused. It localizes the pain generator in a region where hip, groin, and spine pathology overlap constantly.

FAI diagnosis coding is genuinely unsettled, and much of the circulating guidance is wrong. Set an internal convention and validate it with your payers.

GoHealthcare Case Study

Educational scenario — details are illustrative and do not identify any actual patient or organization.

Clinical Scenario

A 27-year-old recreational athlete reports eighteen months of right groin pain worsened by prolonged sitting and pivoting. Examination reproduces the pain with flexion, adduction, and internal rotation. Radiographs show preserved joint space with a cam lesion at the head-neck junction and mild focal acetabular over-coverage. MR arthrography describes an anterosuperior labral tear. A diagnostic intra-articular injection produced substantial temporary relief. The surgeon plans femoroplasty, acetabular rim trimming, and labral repair.

Documentation and Coding Challenges

The authorization request listed all three intended procedures as 29914, 29915, and 29916. It described the radiographs as showing "no significant arthritis" without quoting joint space, and did not mention the injection response. The billing team planned to report all three codes, with modifier 59 appended to overcome the anticipated edit.

Barriers

The requested combination is prohibited. CPT® instructs that 29916 may not be reported with 29915, and a distinct-service modifier does not change that — the planned billing approach would have produced a denial that was correct and unappealable. Separately, the request omitted the two elements that most strengthen a hip arthroscopy case: the quoted joint space measurement and the intra-articular injection response.

Payer Considerations

The plan's criteria set thresholds on joint space and arthritis grade and required confirmation that the hip was the pain generator. It did not dispute that the patient had femoroacetabular impingement.

Resolution Strategy

Re-mapped the request to 29914 with 29916, selecting labral repair over acetabuloplasty as the principal intent, and asked the surgeon to state that intent in the operative plan.

Removed the planned modifier 59 approach and documented internally that the pair is prohibited by CPT® rather than by a bypassable edit.

Quoted the radiographic joint space measurement and arthritis grade directly from the report.

Added the intra-articular injection date and the documented response, establishing the hip as the pain generator.

Quoted the MR arthrography sentence describing the anterosuperior labral tear and the cam morphology.

Outcome

The request was approved without a peer-to-peer. The operative note documented the rim trimming as performed but recorded labral repair as the principal intent, supporting the reported combination. The claim matched the authorization and paid without a bundling adjustment.

Lessons Learned

A prohibited code pair is not an edit to be modified around; it is a coding error, and planning to append a modifier compounds it.

Where two codes are mutually exclusive, the operative note's statement of principal intent is what supports the selection.

Joint space and injection response are the two most under-supplied elements in hip arthroscopy requests, and both are easy to capture.

GoHealthcare Best Practices

Encode the CPT® parenthetical matrix as a hard constraint in the coding workflow.

Require a principal-intent statement in the operative plan where acetabuloplasty and labral repair are both contemplated.

Quote radiographic joint space and arthritis grade in every request.

Capture and document intra-articular injection response wherever the pain generator is ambiguous.

Adopt and document an organizational convention for FAI diagnosis coding.

Identify labral reconstruction, open preservation, and peritrochanteric procedures pre-service.

Never plan a distinct-service modifier to overcome a CPT®-prohibited pair.

Re-verify the governing guideline version each authorization cycle.

Common Mistakes

Reporting 29915 and 29916 together — prohibited by CPT® regardless of documentation.

Appending modifier 59 in an attempt to unbundle a CPT®-prohibited pair.

Reporting 29862 or 29863 alongside 29914, 29915, or 29916.

Reporting capsular closure separately; it is inclusive.

Reporting acetabular chondroplasty separately with a labral repair.

Reporting diagnostic arthroscopy (29860) with a surgical hip arthroscopy.

Reporting 29916 for a labral reconstruction, which has no dedicated code and is reported as 29999.

Submitting a request on imaging morphology alone without concordant examination findings.

Omitting joint space and arthritis grade from the request.

Adopting FAI diagnosis codes from secondary coding content without verification — circulating sources on this topic contain outright errors.

Pearls and Pitfalls

Pearls	Pitfalls
Encode the parenthetical matrix as a hard rule.	Treating it as an edit with a modifier bypass.
State principal intent in the operative plan.	Reporting both 29915 and 29916.
Quote joint space and arthritis grade.	Asserting "no significant arthritis" unsupported.
Document the injection response.	Leaving the pain generator ambiguous.
Set an internal FAI diagnosis coding convention.	Coder-by-coder variation across one surgeon's cases.
Flag unlisted-code procedures pre-service.	Discovering the gap at claim submission.

Frequently Asked Questions

Q1. Which codes report femoroacetabular impingement surgery? 29914 (femoroplasty, treatment of cam lesion), 29915 (acetabuloplasty, treatment of pincer lesion), and 29916 (labral repair). These three were added specifically for FAI.

Q2. Can 29915 and 29916 be reported together? No. CPT instructs that 29916 may not be reported in conjunction with 29915. Where both an acetabuloplasty and a labral repair are performed, report one or the other based on the principal intent of the operation.

Q3. Will modifier 59 allow me to report both? No. This is a CPT parenthetical instruction, not an NCCI edit with a bypass indicator. The combination is incorrect regardless of documentation or modifier.

Q4. What is the most common valid FAI combination? 29914 with 29916 — femoroplasty plus labral repair.

Q5. Can debridement or synovectomy be reported with the FAI codes? No. CPT instructs that 29916 may not be reported with 29862 or 29863, and that 29914 and 29915 may not be reported with 29862 or 29863.

Q6. Is capsular closure separately reportable? No. Capsular closure is included in these hip arthroscopy procedures and should not be reported separately. Acetabular chondroplasty is likewise inclusive.

Q7. What is the difference between 29862 and 29916? 29862 covers debridement, abrasion arthroplasty, and/or resection of the labrum. 29916 covers labral repair — suturing and reattaching the labrum. They describe different procedures and are not interchangeable.

Q8. How is labral reconstruction coded? There is no dedicated code. Labral reconstruction, as distinct from repair, is reported with 29999 (unlisted procedure, arthroscopy) with the operative report and a comparison code.

Q9. How are open hip preservation procedures coded? 27299 (unlisted procedure, pelvis or hip joint). Periacetabular osteotomy, open osteochondroplasty, and open labral repair have no dedicated codes; published guidance suggests referencing established osteotomy codes or 29914 and 29916 as comparisons.

Q10. Can diagnostic hip arthroscopy be billed with a surgical hip arthroscopy? No. 29860 carries a "separate procedure" designation and is not reported alongside a surgical hip arthroscopy of the same hip.

Q11. What is the ICD-10 code for femoroacetabular impingement? There is no single dedicated ICD-10-CM code for FAI. Coding practice combines codes from several families, including M24.85- (other specific joint derangements of hip, NEC), M24.15- (other articular cartilage disorders, hip), and M25.85- (other specified joint disorders, hip), with the traumatic S73.19- family where applicable. Verify against primary sources and AHA Coding Clinic.

Q12. Why does published coding guidance on FAI conflict so much? Because no dedicated code exists, and much of the circulating content is unreliable. In preparing this guide we encountered widely distributed sources citing a rotator cuff repair code for a hip labral tear and a recurrent-dislocation code for FAI. Verify before adopting.

Q13. What imaging is expected? Radiographs establishing joint space, arthritis grade, cam or pincer morphology, and acetabular coverage, plus MRI or MR arthrography characterizing labral and chondral pathology.

Q14. Why is joint space so important? Outcomes of hip arthroscopy deteriorate substantially in the presence of established osteoarthritis. Payer criteria commonly set thresholds on joint space and arthritis grade, and this is the most predictable denial in the procedure.

Q15. Is imaging morphology alone sufficient to justify surgery? No. Cam morphology is common in asymptomatic hips. Criteria require concordant symptoms and examination findings reproducing the pain, not morphology in isolation.

Q16. Why does an intra-articular injection matter? Hip, groin, and lumbar pathology overlap constantly. A documented injection response localizes the pain generator to the hip joint while also satisfying a conservative-care element.

Q17. Is a conservative-care trial required? Generally yes, including hip-specific physical therapy and activity modification with dates and outcomes. Septic arthritis, mechanical block from a loose body, and acute traumatic injury are recognized exceptions.

Q18. How are extra-articular hip procedures handled? Gluteal tendon repair, ischiofemoral impingement, and subspine impingement procedures frequently lack recognized codes and may be reviewed on separate criteria. TurningPoint's 2026 updates addressed both intra-articular and extra-articular hip surgery presentations. Identify these pre-service.

Q19. Which arthroscopic hip procedures have no dedicated code? Published professional coding guidance names iliopsoas tendon release, gluteus repair, trochanteric bursectomy, piriformis release, quadratus femoris release, and arthroscopic fixation of a bone fragment with screws. Labral reconstruction, ischiofemoral impingement, and subspine impingement procedures also lack dedicated codes. All follow an unlisted-code pathway.

Q20. Which Evolent/NIA guideline applies? NIA_CG_314 (Hip Arthroscopy), which groups 29914, 29915, and 29916 as FAI Hip Surgery and 29860, 29861, 29862, and 29863 as Hip Surgery — Other, with a UM matrix defining allowable billed groupings.

Q21. Which eviCore guideline governs? CMM-314 (Hip Surgery — Arthroscopic and Open Procedures). Hip arthroplasty runs separately under CMM-313. Note that CMM-314 was revised with no clinically impactful changes in the February 2026 cycle, while CMM-313 was revised with coverage-limiting changes effective 03/07/2026.

Q22. Does traditional Medicare require prior authorization? No. There is no NCD or dedicated LCD, and hip arthroscopy is not in the OPD prior-authorization program. Medicare Advantage plans generally do require prior authorization.

Q23. What are the most common avoidable denials? Established arthritis beyond the criteria threshold, morphology without concordant symptoms, undated conservative care, and requesting code combinations that CPT prohibits.

Q24. Where does detailed reimbursement analysis belong? Fee schedules, payment rates, NCCI/MUE tables, and revenue-cycle modeling belong in the GoHealthcare Revenue Cycle Knowledge Center, not in this operational guide.

Key Takeaways

CPT® parentheticals — not just NCCI edits — govern this family and apply to every payer.

29915 and 29916 are mutually exclusive; select by principal intent and document it.

29862 and 29863 are prohibited with 29914, 29915, and 29916.

Capsular closure and acetabular chondroplasty are inclusive and never separately reportable.

29914 with 29916 is the workhorse valid combination.

Labral reconstruction, open preservation procedures, and peritrochanteric work lack dedicated codes.

Joint space and arthritis grade are the threshold criteria; concordance of symptoms with morphology is the second gate.

ICD-10-CM has no dedicated FAI code, and much circulating coding content on this topic is erroneous.

Future Outlook

Pressure will continue for dedicated codes covering labral reconstruction, open hip preservation, and peritrochanteric procedures, all of which currently rely on unlisted codes.

A dedicated ICD-10-CM code for femoroacetabular impingement would resolve substantial coding variation and remains a plausible future addition.

Payer criteria will continue to concentrate on joint space and arthritis thresholds as longer-term outcome data accumulates.

Hip preservation is consolidating into specialized centers, which will sharpen the distinction between arthroscopic and osteotomy pathways.

Capsular management and post-less positioning will remain technique variables outside the code set.

Extra-articular hip endoscopy will continue to expand ahead of both the code set and payer criteria.

Document History

Version	Date	Summary
1.0	July 2026	Initial publication under GoHealthcare Clinical Procedure Guide Standard v1.0, opening the Orthopedic Surgery — Hip batch. Two-pass code audit applied at authoring under the standing rule that official long descriptors and primary sources are verified rather than summaries. CPT® descriptors and parenthetical prohibitions verified against CPT® Assistant and published specialty-society coding guidance. ICD-10-CM families verified against CMS code files; because ICD-10-CM contains no dedicated femoroacetabular impingement code, diagnosis coding is presented as unsettled rather than resolved, with an explicit caution that circulating secondary coding content on this topic was found to contain outright errors including a rotator cuff repair code cited for a hip labral tear. Payer content reflects eviCore CMM-314 and CMM-313, Carelon Joint Surgery, and TurningPoint 2026 updates.
