Overview
Basivertebral nerve ablation is an implant-free radiofrequency treatment for chronic vertebrogenic low back pain associated with Type 1 or Type 2 Modic changes at L3-S1. The central operational risk is its narrow coverage profile: the record must align the pain pattern, MRI findings, failed conservative care, treated levels, frequency limits, and Medicare KX attestation before scheduling and billing.
GoHealthcare operational objective
Align the clinical record, payer policy, authorization, scheduled service, coding, and claim before the procedure occurs. This reduces avoidable delays, peer-to-peer escalation, denials, and post-payment exposure.

Evidence at a Glance
Intraosseous basivertebral nerve ablation (BVNA) is an image-guided, implant-free, minimally invasive procedure that uses radiofrequency energy to thermally destroy the basivertebral nerve (BVN) within the vertebral body, interrupting transmission of chronic vertebrogenic low back pain. Unlike vertebroplasty and kyphoplasty, which stabilize a fracture, BVNA treats a distinct pain generator: degenerated vertebral endplates evidenced by Type 1 or Type 2 Modic changes on MRI. The best-known system is the Intracept(R) Procedure; the device market now also includes Stryker OptaBlate(R) BVN and Merit Medical ViaVerte(R).
| Domain | Summary Position (verify per payer / date of service) |
|---|---|
| Medicare NCD | No National Coverage Determination for BVNA (Medicare has no NCD for non-facet joint interventions). |
| Medicare LCD | Noridian twin LCDs L39642 (Jurisdiction JE) and L39644 (Jurisdiction JF), both effective 01/28/2024, with companion Billing and Coding Articles A59466 and A59468. A 03/05/2026 revision applies; NGS has a proposed policy in development (DA60324). Criteria are highly specific and largely uniform. |
| Commercial coverage | Increasingly covered as medically necessary with criteria that mirror the Medicare LCD (BCBS plans, and Medicare Advantage plans adopting the Noridian LCDs). Some commercial plans still treat out-of-criteria BVNA as investigational; verify the specific policy and edition. |
| Evidence level | Supported by a sham-controlled RCT (SMART; Fischgrund, Eur Spine J 2018) with 2- and 5-year durability, and a standard-care-controlled RCT (INTRACEPT; Khalil/Smuck/Koreckij, Spine J 2019). LCD reviewers characterized the evidence as moderate-quality and found BVNA effective versus sham and superior to continued standard care. |
| Image guidance | Fluoroscopic (77003) and CT (77012) guidance are inherent and bundled into 64628/64629 (not separately reportable). |
| Prior authorization | Commonly required by commercial and Medicare Advantage plans; frequently delegated to eviCore, Carelon, or TurningPoint. Traditional Medicare does not prior-authorize but enforces strict LCD criteria and requires the KX modifier to attest compliance. |
| Conservative therapy | A genuine, documented failure of at least 6 months of non-surgical management (generally at least 3 modalities) is required - a real prerequisite, unlike the acute-fracture augmentation pathway. |
| Key imaging | MRI demonstrating Type 1 or Type 2 Modic changes at the vertebral endplates between L3 and S1 is the single decisive coverage element. |
| Coding snapshot | 64628 (first 2 vertebral bodies, lumbar or sacral) and +64629 (each additional vertebral body). Image guidance bundled. Medicare requires the KX modifier; modifier 52 applies if only one body/one endplate is treated. |
| Frequency limits (Medicare) | L3-S1 only; once per named vertebral body per lifetime; no more than 4 vertebral bodies per beneficiary lifetime; no more than 2 levels per session; may not be combined with facet or epidural intervention in the same session. |
Clinical Foundation
Procedure Overview
Chronic low back pain (CLBP) has many potential sources. Vertebrogenic pain is a specific, increasingly recognized subtype originating from damaged vertebral endplates rather than from the disc, facet joints, or nerve roots. The basivertebral nerve travels within the vertebral body and carries nociceptive signals from the endplates; when the endplates degenerate - a process visualized as Type 1 or Type 2 Modic changes on MRI - the result can be deep, midline, axial low back pain that is characteristically worse with sitting, bending, and axial loading. BVNA is an implant-free, minimally invasive, typically outpatient procedure in which access instruments create a path to the basivertebral nerve trunk and radiofrequency energy is applied to thermally ablate it. Because no hardware is left behind, there is no device-related MRI conditionality concern, and the vertebral body remains available for future
imaging. The procedure targets the L3 through S1 vertebral bodies, where the treatable BVN anatomy and the supporting evidence are concentrated. This guide is written for the teams that must consistently obtain authorization and clean reimbursement: physicians and advanced practice providers who document, prior authorization and utilization management staff who submit and defend requests, revenue cycle and coding professionals, and ASC / hospital outpatient department leaders. BVNA carries unusually specific coverage criteria and strict lifetime frequency limits, so documentation precision and coding discipline - including the KX modifier on Medicare claims - are decisive.

Relevant Anatomy
Only anatomy relevant to selection, medical necessity, and documentation is summarized. The vertebral body is the anterior weight-bearing element of the vertebra; its superior and inferior surfaces are the endplates that interface with the intervertebral discs.
- Vertebral endplates are the pain-relevant structures. Endplate degeneration and the associated marrow changes (Modic changes) are the substrate of vertebrogenic pain.
- Basivertebral nerve (BVN) enters the posterior vertebral body through the basivertebral foramen and branches toward the endplates; its main trunk within the vertebral body is the therapeutic ablation target.
- L3 through S1 vertebral bodies are the covered treatment region; the evidence base and the coverage criteria are confined to these levels.
- Adjacent neural structures (nerve roots, spinal canal) are relevant to procedural safety and to excluding radicular or stenotic pain as the dominant, non-vertebrogenic pain source.
Clinical Foundation
Clinical Indications
BVNA is indicated for chronic vertebrogenic low back pain in appropriately selected, skeletally mature patients whose imaging and clinical picture point to the vertebral endplate as the pain generator. The recognized indication profile is narrow and specific:
- Chronic low back pain of at least 6 months' duration, with axial low back pain as the dominant symptom.
- Failure to improve despite documented non-surgical management of at least 6 months (generally at least 3 modalities).
- MRI demonstrating Type 1 or Type 2 Modic changes at the vertebral endplates between L3 and S1, correlating with the clinical presentation.
- Absence of another dominant pain source (radiculopathy, symptomatic stenosis, deformity, fracture, tumor, or infection) that would better explain the symptoms.
Clinical Foundation
Patient Selection
Selection is unusually criteria-driven for BVNA because both the evidence and the coverage policies define a narrow eligible population. Documentation should affirmatively establish each element.
- Skeletally mature adult (18 years or older).
- Chronic (6 months or longer) axial-dominant low back pain refractory to at least 6 months of conservative care.
- MRI Type 1 or Type 2 Modic changes at L3-S1 endplates correlating with the clinical level.
- Vertebrogenic pain pattern on history and examination (axial, midline, worse with loading/sitting).
- Exclusion of competing dominant pain generators (radicular, stenotic, deformity, fracture, tumor, infection) by history, examination, and imaging.
- Physical and psychological ability to tolerate and benefit from the procedure.
Clinical Foundation
Contraindications and Precautions
The BVNA contraindication list is both clinical and, importantly, a coverage-exclusion list; several of these conditions render the procedure non-covered under the Medicare LCDs.
- Skeletal immaturity (under 18 years of age) - non-covered.
- Dominant radicular pain, symptomatic spinal stenosis, or neurogenic claudication - the pain source is not vertebrogenic; non-covered.
- Metabolic bone disease or osteoporosis, metastatic tumor, or other vertebral pathology (fracture, infection, deformity, prior surgical change at the level) that could cause the symptoms or complicate the procedure - generally non-covered/precluded.
- Active local or systemic infection, uncorrectable coagulopathy, or inability to undergo the procedure safely.
- Imaging suggesting an alternative etiology for the low back pain on MRI, flexion/extension radiographs, or CT.
Coverage and Medical Necessity
Medical Necessity
Medical necessity for BVNA rests on a tight convergence of a vertebrogenic pain pattern, a failed conservative-care trial of adequate duration, and MRI Modic changes at L3-S1 - with affirmative exclusion of competing pain generators. Because the eligible population is narrow, the record must speak to each element explicitly.
Elements that consistently establish medical necessity
- Chronic (6 months or longer) axial-dominant low back pain with a documented vertebrogenic pattern.
- Failure of at least 6 months of conservative care, with the specific modalities and outcomes listed.
- MRI Type 1 or Type 2 Modic changes at L3-S1 endplates correlating with the treated level.
- Affirmative exclusion of radicular, stenotic, deformity, fracture, tumor, and infectious etiologies.
- Skeletal maturity and the physical/psychological ability to benefit.
- A level-specific medical-necessity statement, and (for Medicare) attestation supporting the KX modifier and the lifetime/session frequency limits.
Coverage and Medical Necessity
Conservative Treatment Requirements
In contrast to acute-fracture augmentation, BVNA requires a genuine, well-documented conservative care trial. Most policies require failure to improve after at least 6 months of non-surgical management, generally spanning at least three modalities. The record should specify what was tried, for how long, and the response.
- Activity modification and avoidance of aggravating activities.
- Physical therapy, a structured/home exercise program, and low-impact conditioning.
- Pharmacotherapy appropriate to the presentation.
- Interventional or adjunctive measures where indicated (for example, epidural or facet injection therapy) and their outcomes.
- Other supportive measures (heat/cold, cognitive/behavioral support) as applicable.
Coverage and Medical Necessity
Diagnostic Prerequisites and Treatment Sequencing
MRI is the linchpin of BVNA coverage. The decisive finding is Type 1 or Type 2 Modic change at the vertebral endplates between L3 and S1. Imaging must also exclude alternative pathology.
Understanding Modic changes
- Type 1 (inflammatory/edematous): endplate/marrow signal that is hypointense on T1-weighted images and hyperintense on T2-weighted images, reflecting edema and vascularized fibrous tissue.
- Type 2 (fatty): replacement of normal marrow by fat, appearing hyperintense on T1-weighted images (and typically iso- to hyperintense on T2), reflecting a more chronic, stable change.
- Both Type 1 and Type 2 are covered indications for BVNA; the change must involve the endplates between L3 and S1 and correlate with the treated level.
Supporting and exclusionary imaging
- MRI to confirm Modic changes and to exclude tumor, infection, fracture, or canal compromise.
- Flexion/extension radiographs and/or CT where needed to exclude instability, deformity, or an alternative etiology.
- Documentation that the imaging findings correlate with the clinical presentation at the treated level(s).
Medicare Policy
CMS National Coverage Determinations and National Guidance
CMS has no procedure-specific National Coverage Determination for intraosseous basivertebral nerve ablation. Medicare coverage is therefore controlled by the applicable Medicare Administrative Contractor, the effective Local Coverage Determination, and its companion Billing and Coding Article for the beneficiary's jurisdiction and date of service.
National coverage rule
No procedure-specific NCD does not mean automatic coverage or automatic noncoverage. The applicable MAC policy, benefit category, documentation, and reasonable-and-necessary standard remain controlling.
Medicare Policy
Medicare LCDs, Billing and Coding Articles, and MAC Guidance
There is no National Coverage Determination for BVNA. Coverage is administered by Medicare Administrative Contractors through Local Coverage Determinations and their companion Billing and Coding Articles. Noridian maintains twin LCDs - L39642 (Jurisdiction JE) and L39644 (Jurisdiction JF), both effective 01/28/2024 - with companion articles A59466 and A59468; a revision applies as of 03/05/2026, and NGS has a proposed policy in development (DA60324). The criteria below synthesize the common Noridian positions. Do not reproduce policy language verbatim; read the LCD that applies to the patient's MAC jurisdiction and date of service.
Coverage criteria (synthesized)
- Skeletally mature patient with chronic low back pain of at least 6 months, with lower back pain as the dominant symptom.
- Failure to adequately improve despite documented non-surgical management of at least 6 months (generally at least 3 modalities).
- MRI Type 1 or Type 2 Modic changes at the endplates between L3 and S1.
- Absence of additional vertebral pathology (fracture, tumor, infection, deformity, trauma, post-surgical change) that could cause the symptoms or complicate the outcome.
- Physical and psychological assessment of the patient's ability to tolerate and benefit from the procedure.
Frequency limits and non-coverage (Medicare)
- Treatment is limited to vertebral bodies L3-S1; each named vertebral body is covered once per lifetime, with no more than 4 individual vertebral bodies treated per beneficiary per lifetime.
- No more than 2 vertebral levels may be treated in a single session.
- BVNA may not be combined with any other paravertebral injection or intervention (facet or epidural) in the same session.
- Prior BVNA of a named vertebral body precludes coverage of that same body again.
- Non-covered for skeletal immaturity (under 18) and for the contraindicated conditions above (including osteoporosis/metabolic bone disease, metastatic tumor, neurogenic claudication, and radicular symptoms) absent a documented explanation of precautionary measures.
- The KX modifier must be appended to the covered CPT code to attest that all LCD requirements are met.

Clinical Evidence
Evidence-Based Clinical and Specialty-Society Guidelines
The evidence base includes a sham-controlled randomized trial and a standard-care-controlled randomized trial, with published durability follow-up. The source guide characterizes the evidence as moderate quality for carefully selected adults with chronic vertebrogenic pain and Type 1 or Type 2 Modic changes. Clinical evidence supports patient selection; it does not replace the controlling payer policy.
Clinical evidence is not payer policy
Use trials, systematic reviews, and specialty-society statements to support patient selection and peer-to-peer discussion. Coverage still depends on the applicable benefit plan, payer policy, MAC jurisdiction, and effective date.

Prior Authorization
Prior Authorization Requirements
A complete BVNA authorization package should identify the delegated reviewer, quote the MRI Modic type and endplate level, document at least six months of failed non-surgical management, exclude a dominant radicular or stenotic pain source, identify the requested vertebral bodies and CPT structure, and confirm session and lifetime capacity. After approval, the authorization number, approved levels, setting, and validity window must match the scheduled service and claim.
Authorization-to-claim integrity
Confirm that the approved code, level, units, site of service, servicing provider, authorization period, and planned procedure match the service that will be performed and billed.
Documentation
Documentation Requirements
Use this as a pre-submission and pre-claim gate. Every item present converts most BVNA requests into first-pass approvals and supports the KX attestation on Medicare claims.
- Chronic axial-dominant low back pain of at least 6 months documented
- Vertebrogenic pain pattern (axial, midline, worse with sitting/loading) described
- Failed conservative care: at least 6 months and at least 3 modalities, with outcomes
- MRI report language identifying Type 1 or Type 2 Modic changes at the endplate level
- Treated level(s) confined to L3-S1 and correlated with imaging
- Competing pain generators (radicular, stenotic, deformity, fracture, tumor, infection) excluded
- Skeletal maturity (18 or older) confirmed
- Physical and psychological ability to benefit assessed
- Lifetime treated-body count and session-level count within limits (<= 4 lifetime, <= 2 per session)
- No prior ablation of the same named vertebral body
- Level-specific medical-necessity statement present
- KX modifier support documented (Medicare); modifier 52 noted if single-body ablation
- Authorization number, approved levels, setting (ASC/HOPD), and validity window on file
Documentation
Documentation Pearls
Drawn from GoHealthcare's experience supporting musculoskeletal specialty practices, these operational patterns most reliably improve approval rates and reduce rework for BVNA.
- Quote the Modic finding verbatim. The MRI report language identifying Type 1 or Type 2 Modic changes at the endplate level is the single most decisive element; paraphrasing it loosely is the most common cause of an otherwise-strong pend.
- Enumerate the conservative-care trial. State the duration (at least 6 months) and list the specific modalities with outcomes; a vague history is the second most common denial.
- Rule out the radicular/stenotic mimic. Affirmatively documenting that pain is axial and vertebrogenic (not radicular or claudicatory) forecloses the most frequent clinical objection.
- Run the lifetime-count check. Track treated bodies across time so a request never exceeds the 4-body lifetime cap or retreats a previously ablated body.
Pearls
- A quoted Modic finding plus an enumerated 6-month conservative-care trial resolves most BVNA pends.
- Affirmatively excluding radicular/stenotic pain establishes the vertebrogenic source reviewers require.
- A lifetime ledger prevents the frequency-cap and retreatment denials that are otherwise easy to miss.
Pitfalls
- Unspecified diagnosis coding (M54.50) that undercuts medical necessity.
- Non-billable differential codes (M48.06) instead of the specific stenosis codes.
- Reflexive KX application without the underlying documentation - a compliance exposure.
Coding
CPT and HCPCS Coding
This overview is operational, not a reimbursement-methodology treatment. Fee schedules, NCCI edit tables, MUE values, and payment rates belong to the GoHealthcare Revenue Cycle Knowledge Center. The coding fundamentals below drive clean BVNA claims.
- Report 64628 for the first two vertebral bodies (a motion segment) and one unit of +64629 for each additional vertebral body.
- Image guidance (fluoroscopy 77003; CT 77012) is included and is not separately reportable.
- Medicare requires the KX modifier on the covered code to attest that all LCD requirements are met.
- If only a single endplate exhibits Modic changes and only one vertebral body is ablated, report 64628 with modifier 52 (reduced services) and document what was reduced.
- Observe MUE limits (commonly 1 unit for 64628 and 2 units for 64629) and the LCD session limit of no more than 2 levels.
- Place of service is typically ASC (24) or hospital outpatient (19/22); the RF probe and access instruments are packaged into the facility payment (BVNA is a device-intensive procedure under OPPS).
- M54.51 (vertebrogenic low back pain) is the diagnosis that supports the service.
| CPT(R) | Descriptor (abbreviated) | Coding Notes |
|---|---|---|
| 64628 | Thermal destruction of intraosseous basivertebral nerve, including all imaging guidance; first 2 vertebral bodies, lumbar or sacral | Primary code; reported once for the first two treated bodies (a motion segment). Effective 01/01/2022 (replaced Category III 0656T). MUE commonly 1. |
| CPT(R) | Descriptor (abbreviated) | Coding Notes |
|---|---|---|
| +64629 | Same; each additional vertebral body, lumbar or sacral (list separately in addition to primary) | Add-on for each additional body; must accompany 64628 and cannot be reported alone. MUE commonly 2. Do not append modifier 51. |
| 77003 / 77012 | Fluoroscopic / CT guidance | Bundled into 64628/64629 - not separately reportable. |
Historical note. Category III codes 0656T/0657T were used before 01/01/2022 and are obsolete for current dates of service.
No distinct HCPCS Level II code is required to report the physician (professional) service for BVNA; the CPT codes above capture the work. Device-related considerations arise in the facility setting:
- The radiofrequency probe, generator, and access instruments are packaged into the facility payment (OPPS APC for HOPD; the ASC payment for ASC) rather than separately billed; BVNA is treated as a device-intensive procedure under OPPS.
- Because packaging rules and any pass-through status change annually, verify device coding against the current CMS OPPS/ASC files rather than carrying forward prior-year assumptions.
Diagnosis Coding
ICD-10-CM Crosswalk
BVNA is supported by a single principal diagnosis, with several codes serving as differentials that must be excluded (and that, if dominant, render BVNA non-covered). Code to the highest documented specificity. Verify against the current MAC article's covered-diagnosis list.
| ICD-10-CM | Description | Role in BVNA |
|---|---|---|
| M54.51 | Vertebrogenic low back pain | Principal covered diagnosis; effective 10/01/2021 (part of the M54.5 split). Requires MRI Modic Type 1 or 2 support; alone it does not establish necessity - the record must document the criteria. |
| G89.29 | Other chronic pain | May be reported secondarily to characterize chronicity when supported by documentation. |
| M54.50 / M54.59 | Low back pain, unspecified / Other low back pain | Non-specific; do not substitute for M54.51 when a vertebrogenic source is documented. |
| M54.16 | Radiculopathy, lumbar region | Differential to exclude; if radicular pain is dominant, BVNA is not indicated/covered. |
| M48.061 / M48.062 | Spinal stenosis, lumbar region without / with neurogenic claudication | Differential to exclude; note 5th/6th-digit specificity (M48.06 is not billable). Symptomatic stenosis/neurogenic claudication is a non-covered indication. |
| M51.36 | Other intervertebral disc degeneration, lumbar region | Differential; discogenic pathology is a distinct entity from endplate-driven vertebrogenic pain. |
| M54.30 / M54.31 / M54.32 | Sciatica, unspecified / right / left side | Differential to exclude; sciatica indicates a non-vertebrogenic, radicular pattern. |
Billing Integrity
Billing Integrity: Modifiers, Units, NCCI, MUE, and Place of Service
| Modifier | Use | Notes |
|---|---|---|
| KX (Medicare) | Required attestation | Append to the covered code to attest that all LCD requirements (Modic changes, conservative-care failure, level, and lifetime/session limits) are met and documented. |
| 52 (reduced services) | Single-body / single-endplate ablation | Append to 64628 when only one vertebral body (one endplate) is treated; document what was reduced. |
| 51 (multiple procedures) | Do not append to +64629 | Add-on codes are exempt from multiple-procedure reduction and from modifier 51. |
| 59 / X{EPSU} | Rarely applicable | Do not use to bypass session or bundling rules; BVNA may not be combined with facet/epidural interventions in the same session. |
| 22 (increased procedural services) | Situational | Only with documentation substantiating significantly increased work; expect manual review. |
This overview is operational, not a reimbursement-methodology treatment. Fee schedules, NCCI edit tables, MUE values, and payment rates belong to the GoHealthcare Revenue Cycle Knowledge Center. The coding fundamentals below drive clean BVNA claims.
- Report 64628 for the first two vertebral bodies (a motion segment) and one unit of +64629 for each additional vertebral body.
- Image guidance (fluoroscopy 77003; CT 77012) is included and is not separately reportable.

- Place of service is typically ASC (24) or hospital outpatient (19/22); the RF probe and access instruments are packaged into the facility payment (BVNA is a device-intensive procedure under OPPS).
- M54.51 (vertebrogenic low back pain) is the diagnosis that supports the service.
Reimbursement
Reimbursement Considerations
Report the professional service with 64628 for the first two treated lumbar or sacral vertebral bodies and +64629 for each additional body when supported. Imaging guidance is included. In the facility setting, the radiofrequency probe, access instruments, and related device costs are generally packaged into the applicable ASC or hospital outpatient payment. Medicare claims require the KX modifier only when the record supports every applicable LCD criterion. Verify current OPPS, ASC, MUE, NCCI, and payer-contract rules before billing.
Authorization does not guarantee payment
Payment remains subject to eligibility, benefit design, coding accuracy, medical necessity, contract terms, claim edits, site of service, and the payer policy in effect on the date of service.
Denial Management
Denial Prevention
- Adopt a structured BVNA intake form capturing Modic type/level, conservative-care duration and modalities, vertebrogenic pattern, and lifetime-count check before submission.
- Require the MRI report (not just the order) and quote the Modic language in the clinical note.
- Code M54.51 when the record supports a vertebrogenic source; reserve M54.50 for truly unspecified pain.
- Maintain a per-patient lifetime ledger of treated vertebral bodies to prevent cap breaches and retreatment.
- Gate the KX modifier behind a completed documentation checklist.
- Confirm the planned device system is recognized by the payer's current policy edition, especially for newer entrants.
Denial Management
Common Denial Reasons
| Denial Rationale | Root Cause | Prevention |
|---|---|---|
| No documented Modic changes | MRI report does not state Type 1 or Type 2 Modic changes at the treated level | Quote the MRI language identifying Modic type and endplate level (L3-S1). |

Appeals
Appeals, Reconsideration, and Peer-to-Peer
BVNA denials are almost always missing-criteria denials. Effective appeals supply the specific element the policy requires rather than re-arguing the therapy.
- Lead with the Modic finding: quote the MRI report identifying Type 1 or Type 2 Modic changes at the specific L3-S1 level.
- Document the conservative-care trial explicitly: at least 6 months, at least 3 modalities, with outcomes.
- Affirmatively exclude radicular/stenotic pain to establish a vertebrogenic source.
- Confirm the level and the lifetime/session counts are within limits.
- Attach the specific LCD or policy criterion satisfied and map the record to each element.
- Prepare the physician for a peer-to-peer focused on the Modic finding, the conservative-care duration, and the vertebrogenic pattern.
Operations
Operational Workflow
This workflow runs from evaluation through scheduling and post-service coding. Traditional Medicare omits pre-service authorization but requires the same substantiation plus the KX modifier on the claim.
- 1. Evaluation and imaging: establish the vertebrogenic pain pattern, obtain MRI documenting Type 1 or Type 2 Modic changes at L3-S1, and exclude competing pain generators.
- 2. Conservative-care verification: confirm and document at least 6 months of failed non-surgical management across the required modalities.
- 3. Benefit and vendor check: identify the plan, the adjudicating vendor (eviCore, Carelon, or TurningPoint), and the applicable policy edition; confirm remaining lifetime/session capacity.
- 4. Clinical assembly: compile the MRI report language (Modic type and level), the conservative-care history, the vertebrogenic pattern, and the level-specific medical-necessity statement.
- 5. Submission: submit with the planned CPT/level detail (64628 and any +64629 levels) and M54.51 as the linked diagnosis.
- 6. Clinical review / peer-to-peer: if pended, supply the missing element (most often the Modic finding or the conservative-care duration); prepare the physician for a focused peer-to-peer.
- 7. Determination and scheduling: record the authorization number, approved level(s), and validity window; schedule within the authorized period and setting (ASC vs HOPD).
- 8. Post-service: code one primary plus add-on levels, append the KX modifier on Medicare claims, and ensure the record supports the lifetime/session limits.
Reviewer Lens
Payer Perspective
Payer Perspective
A reviewer is likely to test four points first: documented Type 1 or Type 2 Modic change at L3-S1, at least six months of failed non-surgical management, a vertebrogenic rather than radicular or stenotic pain pattern, and compliance with level, session, and lifetime limits. Missing one of these elements commonly results in a pend or denial even when the patient may otherwise be clinically appropriate.
Clinical Pearls
Clinical Pearls
Pearls
- A quoted Modic finding plus an enumerated 6-month conservative-care trial resolves most BVNA pends.
- Affirmatively excluding radicular/stenotic pain establishes the vertebrogenic source reviewers require.
- A lifetime ledger prevents the frequency-cap and retreatment denials that are otherwise easy to miss.
Pitfalls
- Unspecified diagnosis coding (M54.50) that undercuts medical necessity.
- Non-billable differential codes (M48.06) instead of the specific stenosis codes.
- Reflexive KX application without the underlying documentation - a compliance exposure.

GoHealthcare Insights
GoHealthcare Insights
Drawn from GoHealthcare's experience supporting musculoskeletal specialty practices, these operational patterns most reliably improve approval rates and reduce rework for BVNA.
- Quote the Modic finding verbatim. The MRI report language identifying Type 1 or Type 2 Modic changes at the endplate level is the single most decisive element; paraphrasing it loosely is the most common cause of an otherwise-strong pend.
- Enumerate the conservative-care trial. State the duration (at least 6 months) and list the specific modalities with outcomes; a vague history is the second most common denial.
- Rule out the radicular/stenotic mimic. Affirmatively documenting that pain is axial and vertebrogenic (not radicular or claudicatory) forecloses the most frequent clinical objection.
- Run the lifetime-count check. Track treated bodies across time so a request never exceeds the 4-body lifetime cap or retreats a previously ablated body.
What experienced PA teams do differently
- They lead the request with the quoted Modic finding and the endplate level.
- They enumerate the 6-month, 3-modality conservative-care trial with outcomes.
- They affirmatively exclude radicular and stenotic pain to establish a vertebrogenic source.
- They maintain a running lifetime-count ledger so no request exceeds 4 bodies or retreats a body.
- They gate the KX modifier behind a completed documentation checklist.
FAQ
Frequently Asked Questions
What condition does BVNA treat?
Chronic vertebrogenic low back pain - pain originating from degenerated vertebral endplates, evidenced by Type 1 or Type 2 Modic changes on MRI. It does not treat fractures, disc herniation, or facet pain.
What are Modic changes and why do they matter?
Modic changes are MRI signal changes at the vertebral endplates/marrow. Type 1 is inflammatory/edematous and Type 2 is fatty. Type 1 or Type 2 changes at L3-S1 are the decisive coverage criterion for BVNA.
Which CPT codes are used?
64628 for the first two vertebral bodies (a motion segment) and +64629 for each additional vertebral body. Image guidance is bundled.
When did the current codes take effect?
64628 and 64629 became effective January 1, 2022, replacing Category III codes 0656T and 0657T.
What is the KX modifier and when is it used?
For Medicare, the KX modifier is appended to the covered code to attest that all LCD requirements (Modic changes, conservative-care failure, level, and frequency limits) are met and documented.
How many levels can be treated in one session?
No more than two vertebral levels per session under the Medicare LCDs.
What is the lifetime limit?
Treatment is limited to L3-S1, once per named vertebral body, with no more than four vertebral bodies per beneficiary per lifetime; a previously ablated body cannot be retreated.
What levels are covered?
Only the L3 through S1 vertebral bodies.
How much conservative care is required?
Generally at least 6 months of failed non-surgical management, typically spanning at least three modalities, documented with outcomes.
What ICD-10 code supports BVNA?
M54.51 (vertebrogenic low back pain), effective October 1, 2021. It requires MRI Modic support and does not, by itself, establish medical necessity.
Can BVNA be combined with a facet or epidural procedure the same day?
No. The LCDs specify BVNA may not be combined with any other paravertebral injection or intervention (facet or epidural) in the same session.
Is image guidance billed separately?
No. Fluoroscopic (77003) and CT (77012) guidance are bundled into 64628/64629.
What if only one vertebral body (one endplate) is treated?
Report 64628 with modifier 52 (reduced services) and document what was reduced.
Is BVNA covered for radicular or stenotic pain?
No. Dominant radicular pain, symptomatic stenosis, and neurogenic claudication are non-covered; the pain must be vertebrogenic.
Is BVNA covered for patients under 18?
No. Skeletal immaturity (under 18) is a non-covered condition.
Does BVNA leave an implant or affect future MRI?
No. BVNA is implant-free; there is no device-related MRI conditionality, and the treated vertebra remains available for future imaging.
Which device systems are available?
The Intracept Procedure (Boston Scientific, formerly Relievant) is the established system; Stryker OptaBlate BVN (FDA cleared May 2025) and Merit Medical ViaVerte (distributed by Medtronic) are newer entrants. Coverage is generally procedure-based.
Who manages commercial prior authorization?
Frequently eviCore (under CMM-208), Carelon, or TurningPoint, depending on the plan.
Does traditional Medicare require prior authorization?
Not for the professional service, but the LCD criteria are enforced at adjudication and on audit, and the KX modifier attestation is required.
What is the strongest evidence for BVNA?
The sham-controlled SMART RCT (Fischgrund, Eur Spine J 2018) with 2- and 5-year durability, and the standard-care-controlled INTRACEPT RCT (Spine J 2019).
What is the single best way to avoid a peer-to-peer?
Quote the Modic finding and enumerate the 6-month conservative-care trial in the first paragraph of the request, and confirm the level and lifetime/session counts.
Case Study
GoHealthcare Case Study
Educational scenario. No actual patient or organization is depicted.
Clinical scenario
A pain practice requests BVNA at L4 and L5 for an adult with two years of deep, midline, axial low back pain worse with sitting and forward flexion. MRI reports Type 2 Modic changes at the L4-L5 endplates. The patient has completed physical therapy, a home exercise program, pharmacotherapy, and a prior epidural injection over more than a year.
Documentation challenges
The initial request stated 'chronic low back pain' with a diagnosis of M54.50, did not quote the Modic finding, and summarized conservative care as 'failed multiple treatments' without duration or a modality list.
Prior authorization barriers
The delegated vendor pended the request for absent Modic documentation, an unspecified diagnosis, and an inadequately documented conservative-care trial, and offered a peer-to-peer.
Payer considerations
The policy required MRI Type 1 or Type 2 Modic changes at L3-S1, at least 6 months of failed conservative care, exclusion of radicular/stenotic pain, and treatment confined to two levels within lifetime limits.
Operational workflow & resolution strategy
The MSO's PA team resubmitted with the MRI report language quoting Type 2 Modic changes at L4-L5, the diagnosis corrected to M54.51, an enumerated conservative-care trial (PT, home exercise, pharmacotherapy, and epidural injection over 14 months with outcomes), and an explicit statement excluding radicular and stenotic pain. The lifetime ledger confirmed no prior ablation and only two levels this session.
Outcome
The request was approved without a peer-to-peer. The claim coded as 64628 for L4-L5 with the KX modifier appended and M54.51 linked.
Lessons learned
- The clinical facts already met criteria; the diagnosis code and documentation packaging were the gap.
- Correcting M54.50 to M54.51 and quoting the Modic finding resolved the core objections.
- The enumerated conservative-care trial and the lifetime-count check supported the KX attestation.
