The Prior Authorization Environment in 2026
Prior authorization is the operational discipline that most determines whether an MSK specialty ASC converts clinical volume into collected revenue. It is also the domain where the environment changed most between 2024 and 2026. Traditional Medicare, which historically imposed almost no prospective authorization on ASC services, now applies prior authorization or prepayment review through two separate initiatives. Medicare Advantage and Medicaid managed care plans are now bound to federal decision timeframes and denial-reason transparency. Commercial plans have simultaneously reduced authorization volume through gold carding while tightening the criteria applied to the procedures that remain.
1.1 The Five Authorization Environments an MSK ASC Operates In
| Environment | Prospective authorization posture | What the ASC must control |
|---|---|---|
| Traditional Medicare — general | No general prior authorization for ASC surgical services. Coverage is enforced retrospectively through NCD and LCD criteria, medical review, and audit. | Documentation that satisfies the applicable LCD or NCD at the time of service, because there is no prospective approval to rely on later |
| Traditional Medicare — ASC Prior Authorization Demonstration | Prior authorization, or prepayment review if bypassed, for five service categories in ten states | Whether the planned service is in a demonstration category; submission to the MAC; UTN capture and placement on the facility claim |
| Traditional Medicare — WISeR Model | Prior authorization or, if not requested, prepayment review for a defined list of select items and services in six states | Whether each scheduled service is on the current WISeR list; submission through the correct participant portal; UTN capture and date-span tracking |
| Medicare Advantage and Medicaid managed care | Prior authorization is standard. Under CMS-0057-F, decisions are due within 72 hours (expedited) and seven calendar days (standard), with specific denial reasons required. | Submission completeness on the first attempt, because a shorter clock is only an advantage to the party whose packet is already complete |
| Commercial and workers' compensation | Highly variable. Frequently delegated to a specialty benefit manager with its own MSK criteria set; increasingly modified by gold-carding programs and state timeline statutes. | Knowing which vendor's criteria govern which plan, at the plan and product level — not the payer brand level; and which state law applies |

The CMS ASC Prior Authorization Demonstration
This is a distinct program from the WISeR Model and is frequently confused with it. It is a five-year Medicare fee-for-service demonstration applying prior authorization to five service categories furnished in ambulatory surgical centers in ten states. It extends to the ASC setting the national prior authorization program that has applied to the same service categories in hospital outpatient departments since the CY 2020 OPPS/ASC final rule (CMS-1717-FC). CMS cited data showing that utilization of these services in the ASC setting increased as the OPD program pushed volume out of the hospital.
| Program | Prior Authorization Demonstration for Certain Ambulatory Surgical Center Services — a five-year Medicare fee-for-service demonstration |
|---|---|
| Service categories | Blepharoplasty and related eyelid and brow procedures; botulinum toxin injections; panniculectomy and excision of excess skin and subcutaneous tissue; rhinoplasty and related services; vein ablation and related services |
| Demonstration states | Phase 1 — California, Florida, Georgia, Maryland, New York, Pennsylvania, and Tennessee. Phase 2 — Arizona, Ohio, and Texas. |
| Phase 1 dates | Prior authorization requests accepted beginning January 5, 2026, for dates of service on or after January 19, 2026 |
| Phase 2 dates | Prior authorization requests accepted beginning February 2, 2026, for dates of service on or after February 16, 2026 |
| Submission channel | To the ASC's Medicare Administrative Contractor — portal, fax, mail, or electronic submission of medical documentation, per MAC instructions |
| If bypassed | Participation is described as optional, but applicable ASC claims submitted without a prior authorization request are subject to prepayment medical review |
| Affirmation output | A unique tracking number that must be reported on the facility claim. Professional claims associated with a denied ASC claim are at risk. |
| Documentation standard | CMS has stated that medical necessity documentation requirements are unchanged — what changes is when the documentation is reviewed |
Why an MSK Center Should Care
This demonstration is not musculoskeletal in its service categories, but it is highly relevant to multispecialty MSK centers and to any center performing vein ablation, panniculectomy, or botulinum toxin injections alongside its orthopedic and pain caseload. The operational risk is that a center in a demonstration state builds an authorization workflow around its MSK volume and never screens the handful of monthly cases that fall into a demonstration category — which then route silently into prepayment review.

The WISeR Model
The Wasteful and Inappropriate Service Reduction (WISeR) Model is a CMS Innovation Center model that launched January 1, 2026 and is scheduled to run through December 31, 2031. It applies to Original Medicare fee-for-service only — not Medicare Advantage — in six states across four Medicare Administrative Contractor jurisdictions: New Jersey, Ohio, Oklahoma, Texas, Arizona, and Washington. Model participants are technology vendors performing technology-assisted medical necessity review alongside human clinical review; CMS has stated that coverage and payment policy are unchanged and that appeal rights are preserved.
For musculoskeletal centers this model is central rather than peripheral. The select items and services list is heavily weighted toward interventional pain and spine procedures commonly performed in ASCs, and the model explicitly reaches the ambulatory surgical center place of service.
| Model period | January 1, 2026 through December 31, 2031 |
|---|---|
| Scope | Original Medicare fee-for-service; six states; select items and services identified in the CMS WISeR Provider and Supplier Operational Guide |
| Sites of service reached | Hospital outpatient, ambulatory surgical center (POS 24), physician office (POS 11), and the home (POS 12), as specified for each service |
| Provider choice | Submit a prior authorization request, or proceed and have the claim routed to prepayment medical review. There is no practical opt-out for listed services. |
|---|---|
| Documentation window | Providers that do not submit a prior authorization request have 45 days from the documentation request to respond under the operational guide |
| Non-affirmation | Unlimited resubmissions permitted; peer-to-peer review available; standard Medicare appeal rights preserved |
| Unique tracking number | An affirmed decision generates a UTN that must appear on the claim. Affirmations carry a defined validity window — approximately 120 days under the operational guide. |
| Exemption pathway | CMS and participants implemented a process beginning in July 2026 to exempt providers demonstrating consistent compliance with Medicare coverage, coding, and payment rules. Exemption is granted at the individual NPI level, not at the facility or organizational level. |
WISeR Operational Risks
Two WISeR failure modes are specific to the ASC and are both avoidable. First, the affirmation belongs to the service, but the claim belongs to multiple parties: if the primary service is non-affirmed, associated services — facility, anesthesia, implanted devices — are exposed along with it. Second, the affirmation has an expiration. A case rescheduled beyond the validity window requires a new request, and centers that treat the UTN as permanent discover the problem only at remittance.
GoHealthcare's standing recommendation is that the WISeR participant-to-state assignment table and the select items and services list be maintained as a separately versioned internal one-pager rather than embedded in durable documents. Both are revised by operational guide version and have changed during the model period.
Three States, Two Programs
Arizona, Ohio, and Texas appear in both the ASC Prior Authorization Demonstration and the WISeR Model. Centers in those three states operate under two distinct Medicare prior authorization regimes with different service lists, different submission channels, and different review entities. Building a single screening step that checks both lists is the practical control.

Federal Prior Authorization Reform — CMS-0057-F
The CMS Interoperability and Prior Authorization Final Rule (CMS-0057-F), released January 17, 2024, restructured prior authorization for Medicare Advantage organizations, state Medicaid and CHIP fee-for-service programs and managed care entities, and qualified health plan issuers on the federally facilitated exchanges. Its provisions arrive in two waves, and knowing which wave a given requirement belongs to prevents a great deal of misplaced expectation.
| Provision | Compliance timing | Practical effect for an ASC |
|---|---|---|
| Decision timeframes — 72 hours expedited, seven calendar days standard | Effective January 1, 2026 | Faster answers, but only for complete submissions. An incomplete packet still consumes the clock and returns a request for information. |
| Specific denial reasons required | Effective January 1, 2026 | Denials become actionable. The stated reason should drive the reconsideration strategy rather than a generic resubmission. |
| Public reporting of prior authorization metrics | Beginning 2026 | Payer-level approval, denial, and turnaround data becomes usable in contracting and escalation conversations. |
| Provision | Compliance timing | Practical effect for an ASC |
|---|---|---|
| Prior Authorization API — requirement determination, documentation surfacing, electronic submission, electronic decision | Generally by January 1, 2027 | The end state is automated requirement discovery and submission from the EHR. Until then, portal and fax workflows remain the operational reality. |
| Patient Access, Provider Access, and Payer-to-Payer APIs | Generally by January 1, 2027 | Continuity of authorization history across plan changes; fewer repeat conservative-care documentation requests |
Scope Limits
Drug authorizations are outside the scope of the CMS-0057-F provisions. The rule also does not apply uniformly to every payer an ASC encounters — commercial plans that are not Medicare Advantage, Medicaid managed care, CHIP, or FFE qualified health plans are governed by state law and contract, not by this rule. The federal rule does not preempt state law, so both layers apply simultaneously. Workers' compensation and auto liability are separate regimes entirely.

ASC Specialty Hub
Commercial Utilization Management for MSK Procedures
Most commercial MSK authorization decisions are not made by the payer whose card the patient carries. They are made by a delegated utilization management vendor applying its own criteria set, on its own revision cycle, through its own portal. The practical consequence is that "we know how this payer thinks" is the wrong unit of knowledge. The right unit is: which vendor's criteria set governs this specific plan and product, at this specific date of service.
| Utilization management entity | What MSK teams should track |
|---|---|
| eviCore healthcare | Musculoskeletal, spine, interventional pain, and joint surgery guideline series, each revised on a versioned cycle with stated effective dates. Guideline tightening events matter more than the guideline text, because criteria satisfied last quarter may not be satisfied this quarter. |
| Carelon Medical Benefits Management | MSK and spine clinical appropriateness guidelines with defined conservative care and imaging expectations. Carelon-derived content carries use restrictions requiring review before commercial republication. |
| Cohere Health | Increasingly used for MSK episodes with an emphasis on episode-level and intelligent authorization rather than single-service review; approvals may be structured across an episode of care. |
| Evolent (including legacy specialty benefit management lines) | MSK and spine surgical review with conservative care documentation emphasis. |
| TurningPoint Healthcare Solutions | Orthopedic and spine surgical quality and utilization programs, frequently delegated by regional and Medicaid plans, with device and implant scrutiny. |
| NaviNet and payer portals | Not criteria sets, but the submission and status channel for many regional plans; portal-specific attachment limits and field conventions are a recurring source of avoidable rework. |
Across vendors and across MSK procedure families, the criteria architecture is remarkably consistent even when thresholds differ. Nearly every MSK authorization decision turns on the same six evidentiary pillars.
| Pillar | What reviewers are actually looking for |
|---|---|
| Diagnosis specificity | A billable, specific ICD-10-CM code that matches the clinical narrative and the procedure requested — not a non-billable parent code and not a symptom code standing in for a diagnosis |
| Duration and severity | Symptom duration stated in weeks or months with a start reference; pain severity with a validated scale; severity internally consistent across the note, the imaging order, and the request |
| Functional impairment | Objective, specific functional limitation — named activities, distances, durations, occupational impact — ideally with a standardized instrument score rather than a narrative adjective |
| Conservative care | Named modalities with dates, duration, and outcome. "Failed conservative therapy" without dates is the single most common reason an otherwise approvable MSK request is denied. |
| Imaging correlation | Current, appropriate imaging whose findings correlate with the symptomatic level, side, and distribution described in the examination |
| Procedure-specific criteria | Diagnostic block response thresholds and intervals, psychological evaluation for implantable therapies, trial response for neuromodulation, injection frequency limits, and similar gates |

ASC Specialty Hub
The ASC Prior Authorization Workflow
The workflow below is the reference model GoHealthcare implements in MSK specialty centers. Its defining feature is that authorization work begins at the clinical decision, not at the scheduling request — and that the authorization is re-verified after it is granted, because a granted authorization that does not match the planned case is worse than no authorization at all.
- Clinical decision and intent capture. The surgeon's plan is captured with the specificity the payer will require: procedure, laterality, spinal level or joint, planned adjuncts, anticipated implant, and intended place of service.
- Coverage determination. Identify the governing rule set — NCD, LCD, ASC demonstration category, WISeR list, MA plan policy, delegated vendor guideline, or workers' compensation schedule — for this patient, this plan, this product, and this date of service.
- Requirement discovery. Determine whether authorization is required, whether a gold-card or model exemption applies, which portal governs, what attachment format is accepted, and what the decision clock will be.
- Clinical documentation assembly. Build the packet against the six evidentiary pillars. Where a required element is missing from the record, obtain it before submission rather than submitting and hoping.
- Medical necessity statement. Compose a concise statement in the payer's own criteria vocabulary that maps each requirement to a specific, page-referenced location in the attached record.
- Submission. Submit electronically wherever available, with a complete attachment set, correct place of service, correct code set, and correct units on the first attempt.
- Status pursuit against the clock. Track to the applicable decision deadline. Where a federal or state timeframe applies, hold the payer to it and document the timeline.
- Authorization integrity verification. On receipt, verify the approval against the planned case, element by element: codes, laterality, level, units, place of service, rendering and facility identifiers, and effective date span. This step prevents more denials than any other.
- Peer-to-peer or reconsideration when adverse. Read the specific denial reason, correct the actual deficiency, and prepare the physician with the exact criterion in dispute rather than a general clinical summary.
- Scheduling release. Release the case only when authorization integrity is confirmed and the remaining scheduling gate items are closed.
- Change control. Any change to date, laterality, level, approach, implant, or surgeon triggers re-verification. Rescheduling past the valid date span is a re-authorization event, not an administrative update.
- Post-service reconciliation. Compare the operative report to the authorization before the claim drops. Where the case exceeded the approved scope, initiate the payer's retrospective pathway immediately rather than after a denial.
The Highest-Yield Control in the Workflow
The verification step at item eight is where GoHealthcare consistently finds the largest single recovery opportunity in MSK centers. Teams celebrate the approval and file it. An approval for a single level when two were planned, for the wrong side, for a hospital place of service, or expiring before the scheduled date is a denial that has already happened and has simply not yet been transmitted. Verification takes minutes; the denial takes months.

ASC Specialty Hub
Common Denial Reasons and What Each Actually Means
| Denial reason as stated | What it usually means operationally | Prevention |
|---|---|---|
| No authorization on file | The authorization exists but under a different facility identifier, tax identification number, or member identifier — or was obtained for the professional only | Verify facility-level authorization separately from professional authorization at credentialing and at every request |
| Service not authorized for this place of service | Approval was issued for an inpatient or hospital outpatient setting | Explicitly state POS 24 on the request and confirm it on the approval |
| Procedure exceeds authorized scope | Additional levels, laterality, or adjunct procedures were performed beyond the approval | Authorize the full anticipated scope; use the payer's retrospective pathway immediately when scope expands intraoperatively |
| Not medically necessary — conservative therapy | Conservative care was performed but documented without dates, duration, or outcome | Structured conservative care capture with modality, start and end dates, and response |
| Not medically necessary — imaging | Imaging is absent, stale, or does not correlate with the symptomatic level or side | Correlate imaging findings to examination findings explicitly in the note |
| Diagnosis not covered / invalid diagnosis | A non-billable parent ICD-10-CM code was submitted, or the diagnosis is not on the covered list | Code to the highest level of specificity; screen every request against the payer's covered diagnosis list |
| Experimental or investigational | The procedure or device is outside the payer's coverage position for this indication | Confirm the coverage position before scheduling; where genuinely contested, prepare the evidentiary argument in advance |
| Frequency or quantity limit exceeded | The service exceeds a per-year or per-episode limit, often counting services performed elsewhere | Query the patient's full treatment history across sites before requesting |
| Bundled / included in another service | A component code was billed separately against an edit | Quarterly edit review at the code-pair level for the center's actual case mix |
| Non-covered ASC service | The procedure is not on the applicable covered procedures list for this payer | Verify list status by payer and by date of service before posting |
| Missing unique tracking number | A demonstration or model affirmation was obtained but the UTN was not reported on the claim | Make UTN capture and claim placement a required field, not a note |

ASC Specialty Hub
Appeal Strategy and Avoiding Unnecessary Peer-to-Peer
A peer-to-peer review is not a victory condition. It is a cost — measured in surgeon time, scheduling delay, and patient anxiety — that a complete initial submission usually avoids. GoHealthcare's position is that peer-to-peer volume is a quality metric for the authorization team, not a workload metric for the physician.
- Appeal the stated reason, not the denial. Since January 1, 2026, impacted payers must give a specific reason. Address that reason first and directly; a generic clinical narrative that ignores the cited criterion rarely reverses.
- Map criteria to evidence. The strongest appeal is a table: the payer's criterion in one column, the specific record location satisfying it in the other. Reviewers approve what they can find.
- Cure defects rather than restate. If the deficiency was undated conservative care, obtain the dates. Resubmitting the same packet with stronger adjectives produces the same outcome more slowly.
- Preserve deadlines. Track internal reconsideration, external review, and — for Medicare — redetermination and reconsideration levels, each with its own clock and submission requirements.
- Use the procedural arguments available under state law. Where a state requires a licensed physician decision-maker for adverse medical necessity determinations, or a same-specialty reviewer, or a specific decision timeframe, a documented procedural failure is an independent basis for challenge. Capture reviewer name, credential, and decision timestamp on every adverse determination.
- Prepare the physician narrowly. Give the surgeon the single criterion in dispute, the specific record evidence, and the specific ask. A five-minute focused call outperforms a twenty-minute general one.
- Escalate patterns, not cases. When the same criterion is misapplied repeatedly, the remedy is a provider relations or medical director escalation with documented examples, not another individual appeal.
- Document everything. Reference numbers, representative names, timestamps, portal confirmations, and screenshots. Where a payer misses a decision timeframe, the documented timeline is the leverage.

GoHealthcare Prior Authorization Insight
This section contains operational knowledge that does not appear in payer policies or clinical guidelines, drawn from GoHealthcare's work supporting musculoskeletal specialty practices, ASCs, and hospital outpatient departments across multiple markets and payer environments.
What Reviewers Actually Do With a Packet
Authorization reviewers work against criteria checklists under production expectations. They are not reading the record the way a colleague would. They are looking for specific, findable evidence of specific, enumerated requirements. A clinically excellent note that buries the required elements in narrative prose will lose to a clinically ordinary note that surfaces them in a structured, labeled format. This is not a statement about clinical quality. It is a statement about how the decision is actually made.
- Findability beats eloquence. Label the elements the criteria name, in the vocabulary the criteria use, with page or section references in the cover statement.
- Front-load the disqualifiers. If the criteria require a diagnostic block response threshold, state the threshold result in the first paragraph, not the fifth.
- Anticipate the automated screen. Many first-pass reviews are algorithmic. Structured, discrete data — specific ICD-10-CM codes, numeric pain scores, dated conservative care — clears automated screening; narrative does not.
- Attach what is referenced. A statement that imaging demonstrates a finding, without the report attached, converts an approval into an information request and restarts the clock.
- Do not over-attach. A two-hundred-page dump signals that the submitter does not know which elements matter. Attach the record that proves the criteria, indexed.
The Four Failures That Cost MSK Centers the Most
| Failure | Why it happens | The control that fixes it |
|---|---|---|
| Authorization scope narrower than the case performed | The request was built from the scheduling entry rather than the surgeon's actual plan | Capture intent at the clinical decision with laterality, level, adjuncts, and anticipated implant; request the full anticipated scope |
| Site-of-service mismatch | The authorization was obtained by a practice-side team accustomed to hospital scheduling | Explicitly state POS 24 in the request and verify it on the approval; make it a required field in the gate |
| Undated conservative care | The clinician documented care that occurred but without the metadata the criteria require | Structured capture at the point of care — not reconstruction by the authorization team weeks later |
| Expired authorization after reschedule | The case moved and no one treated the move as an authorization event | Reschedule triggers automatic re-verification of the date span; build it into the scheduling system, not the checklist |
Internal Quality Assurance for the Authorization Function
- Pre-submission audit of a defined sample against the six evidentiary pillars, scored and trended by specialist
- Post-approval integrity audit — 100 percent verification that the approval matches the planned case, not a sample
- Denial root-cause categorization assigned to the owning department, reviewed weekly, with the top three causes given a named owner and a due date
- Peer-to-peer post-mortem: what was missing from the initial submission that made the call necessary
- Payer behavior log capturing criteria changes, portal changes, turnaround deviations, and reviewer patterns — reviewed monthly
- Physician-specific feedback loop delivering documentation gaps back to the clinician in a form usable at the point of care
- Quarterly criteria refresh confirming the guideline version in use for each delegated vendor and each major plan
- Monthly screen of the scheduled case list against the current ASC demonstration categories and WISeR select items and services list, where applicable

GoHealthcare Case Study
The following case study is original and educational. It does not describe any actual patient, physician, facility, or organization, and any resemblance to a specific entity is coincidental. Payer names are described generically.
Clinical Scenario
A three-operating-room musculoskeletal ASC in a WISeR-participating state performs a mixed schedule of interventional pain, spine, and orthopedic sports medicine cases. Over two quarters, the administrator observes that net collections per case have declined approximately eleven percent while case volume has grown, and that same-day cancellations have doubled. Denial volume has increased but no single denial reason dominates — which is why the problem went unaddressed for two quarters.
Documentation and Authorization Barriers
- Conservative treatment was documented narratively — "failed conservative management" — without modality, dates, duration, or response.
- Operative reports for multi-level procedures described the case as a single narrative, forcing coders to infer which levels and which distinct procedures were performed.
- Authorization requests were generated from the scheduling entry, which captured the procedure name but not laterality, level count, or anticipated adjuncts.
- Two of the center's highest-volume commercial plans had moved to a delegated specialty benefit manager whose criteria set had tightened at a version release; the authorization team was still working from the prior version's expectations.
- Several traditional Medicare cases involving listed services were scheduled without a WISeR prior authorization request, defaulting to prepayment review.
- Rescheduled cases were treated as administrative updates, not authorization events. Several proceeded on expired approvals.
Operational Workflow and Payer Considerations
Authorization sat inside the surgical scheduling function and was staffed to transaction volume. There was no post-approval verification step. Coding received operative reports two to five days after the case, by which time any authorization scope problem was unfixable. Denials were worked individually by aging rather than categorized by root cause, which is why no single reason appeared dominant — the same three upstream failures were producing six different denial codes. The delegated vendor's tightened guideline had introduced a stricter documented duration requirement for conservative care and an imaging correlation expectation the center's notes did not consistently satisfy. Neither change was announced to the practice; both were discoverable in the vendor's published guideline versioning.
Resolution Strategy
- Separated the authorization function from scheduling, with a defined pre-service clinical validation role and a written scheduling gate.
- Implemented intent capture at the clinical decision: laterality, level, adjuncts, anticipated implant, and place of service recorded by the surgeon's team at the time the case was decided.
- Added 100 percent post-approval integrity verification comparing every element of the approval to the planned case before schedule release.
- Built structured conservative care capture into the clinic workflow with modality, dates, duration, and response as discrete fields.
- Established a quarterly criteria refresh confirming the governing guideline version for each delegated vendor and each major plan.
- Created a Medicare screening step at scheduling that checked each planned service against the current WISeR select items and services list, with UTN capture and date-span tracking.
- Made rescheduling an automatic authorization re-verification trigger inside the scheduling system rather than a checklist item.
- Instituted operative-report-to-authorization reconciliation before claim submission, with immediate initiation of the payer's retrospective pathway for scope expansion.
- Converted denial management from aging-based to root-cause-based, with the top three causes assigned a named owner and a due date each week.
- Set a standing agenda item at the governing body for authorization and denial performance.
Within two quarters, first-pass authorization approvals rose materially, peer-to-peer volume fell by more than half, same-day cancellations returned to baseline, and net collections per case recovered and exceeded the prior baseline. The recovery came almost entirely from prevention rather than appeal: the appeals team's workload declined rather than increased.
- A diffuse denial pattern usually has a concentrated cause. Six denial codes were expressing three upstream failures. Aging-based denial work structurally conceals this; root-cause categorization reveals it in a week.
- Authorization is a clinical data problem before it is an administrative one. The fix lived in the clinic note and the surgeon's intent capture, not in the authorization queue.
- Criteria change silently. A vendor guideline version release is not announced to the practice. Quarterly refresh is a control, not an administrative nicety.
- Rescheduling is an authorization event. Systems, not checklists, should enforce this.
- Verification outperforms appeal by an order of magnitude. The highest-return intervention in the entire remediation was a verification step measured in minutes per case.

Key Takeaways
- Traditional Medicare now has two distinct prior authorization layers reaching ASCs — the ASC Prior Authorization Demonstration in ten states and the WISeR Model in six. Arizona, Ohio, and Texas are in both.
- CMS-0057-F shortened the clock without changing the criteria. Faster decisions advantage only the party whose submission was already complete.
- The authorization is the elements, not the number. Post-approval integrity verification is the single highest-yield control in the ASC revenue cycle.
- Undated conservative care is the most common cause of an avoidable MSK denial.
- Peer-to-peer volume is a metric about your submissions, not about the payer.
- Delegated vendor criteria change by version release without notice to the practice. Quarterly refresh is a control.
- State law provides procedural appeal grounds — decision timeframes, same-specialty review, human decision-maker requirements — that are often faster than the clinical argument. See Page 13.
