Monitor payer policy activity
Outpatient cognitive rehabilitation coverage and the medical policy stance on coma stimulation for UnitedHealthcare Community Plan members in Pennsylvania. It governs prior authorization and medical necessity considerations for outpatient services in that state.
Supporting information sections (Description of Services, Clinical Evidence, and References) were updated to reflect current literature.
Updated reference link to the Pennsylvania Code § 55.1101.31(f) and revised definitions for Cognitive Rehabilitation and Coma Stimulation.
Coverage Criteria
inv-01: Cognitive Rehabilitation — Covered with criteria
Covered when ALL of the following are met (per referenced InterQual outpatient rehabilitation criteria):
Policy defers to InterQual for specific patient-level criteria and duration; this policy applies to outpatient services only.
inv-02: Coma Stimulation — Not Medically Necessary
Not covered:
Controlled trials are limited and heterogeneous; systematic reviews and meta-analyses do not demonstrate consistent, reproducible clinical benefit.
This policy applies to outpatient Cognitive Rehabilitation services only. Coverage determinations, medical necessity review, and prior authorization described in this policy are limited to outpatient settings; inpatient, residential, or other site-of-service programs may be governed by separate UnitedHealthcare policies or contractual provisions.
The American Academy of Neurology (AAN) practice guideline (reaffirmed 2021) does not endorse specific stimulation treatments for patients with a prolonged disorder of consciousness and states there are no established therapies for children with a prolonged disorder of consciousness; families should be counseled regarding the limitations of existing evidence for unsupported interventions.
Coma Stimulation (also termed coma arousal, coma responsiveness, multisensory stimulation, or coma care programs) refers to the application of structured multisensory inputs intended to promote activation and recovery of consciousness. Current evidence is limited and heterogeneous, and such programs are considered unproven and not medically necessary for any Disorder of Consciousness due to insufficient evidence of consistent, reproducible clinical benefit.

Provider Actions & Billing Notes
Prior authorization and medical necessity summary
This Pennsylvania-only policy requires prior authorization review (PARP) and applies InterQual LOC: Outpatient Rehabilitation & Chiropractic medical necessity criteria for outpatient cognitive rehabilitation; coma stimulation is explicitly considered not medically necessary. Providers must request prior authorization when required by the member's plan and ensure documented medical necessity aligns with the referenced InterQual criteria for outpatient cognitive rehabilitation.
- Policy applies only to Pennsylvania and PARP exceptions are evaluated per Pennsylvania Code § 55.1101.31(f).
- Reference InterQual LOC: Outpatient Rehabilitation & Chiropractic for patient-level medical necessity criteria.
Check prior authorization per member plan
Check the member's specific plan, federal/state/contractual requirements, and any UnitedHealthcare tools (including InterQual) for plan-level prior authorization requirements before delivering services.
- Use UnitedHealthcare Medical Policy and third‑party tools (e.g., InterQual) to determine prior authorization needs.
- Verify whether the member's plan requires PARP submission or other authorization workflows.
PARP case‑by‑case evaluation and geographic applicability
Requests for services that do not meet criteria set in the Prior Authorization Review Panel (PARP) will be evaluated on a case‑by‑case basis; services outside Pennsylvania are not covered under this policy.
- If a request falls outside PARP criteria, expect individualized review and potential denial.
- Do not rely on this policy for members outside Pennsylvania—coverage not governed by this policy.
Verify applicable federal/state/contractual benefits
Verify and document that the member's federal, state, or contractual benefit plan permits the requested service; in the event of conflict, plan-specific requirements govern and may result in denial if the service is not covered by those terms.
- Before relying on this policy, check and record applicable federal, state, or contractual benefit plan terms.
- If plan terms differ from standard UnitedHealthcare policy, follow the plan terms.
Coding reference and documentation note
Use the listed procedure codes for reference when documenting services: CPT 97129 (initial 15 minutes) and 97130 (each additional 15 minutes) for cognitive rehabilitation, and HCPCS S9056 for coma stimulation per diem; inclusion of codes does not guarantee coverage or payment.
- Listing of codes is for reference only and does not imply coverage or reimbursement.
- Benefit coverage is determined by federal, state, or contractual requirements and applicable laws.
Verify plan-specific coverage and document checks
Prior to providing services, verify plan‑specific coverage and document that applicable federal, state, or contractual requirements for the member's benefit plan were checked.
- Document verification of the member's plan terms and any required authorizations.
- Record use of InterQual or other tools relied upon to establish medical necessity.
PARP exceptions — submit for individual evaluation
Submit requests that fall outside standard PARP criteria as exception requests to PARP; these will be evaluated individually in accordance with Pennsylvania Code § 55.1101.31(f).
- Include clinical justification and any supporting InterQual findings when requesting a PARP exception.
- Be prepared for case‑by‑case review and potential denial if evidence does not support medical necessity.
Benefit verification and contractual requirements govern coverage
Confirm benefit verification and contractual requirements govern coverage decisions; in conflicts between this policy and a member's plan, follow the federal, state, or contractual benefit plan terms.
- Coverage decisions must reference the member's plan; document any discrepancies and the plan provision relied upon.
- UnitedHealthcare policies and third‑party tools are aids but do not supersede contractual or legal plan terms.
Background
Cognitive impairment after brain injury can affect memory, attention, executive function, language, and visuoperceptual abilities. The aim of Cognitive Rehabilitation is to restore or compensate for these deficits through targeted, functionally oriented therapeutic activities — using restorative (skill retraining) and compensatory (strategy and aid) approaches — when outpatient medical necessity criteria are met.

OpenPayer is powered by Trek Health's payer performance platform. Trek continuously ingests, validates, and normalizes Transparency in Coverage data alongside payer policies and other commercial payer data to create a structured payer intelligence foundation. OpenPayer uses this foundation to deliver personalized search results, dynamically generated policy pages, and tailored policy monitoring based on each user's payers, specialties, billing codes, and areas of interest. The same intelligence powers broader payer performance workflows, including reimbursement benchmarking, contract evaluation, payer negotiations, and financial decision-making.
