Rehab Cognitive denied as not medically necessary by UnitedHealthcare?

UnitedHealthcare's specific coverage criteria for rehab cognitive are defined in its own published medical/coverage policy and the FDA-approved prescribing label. A successful appeal documents that your medical records satisfy each criterion those sources list — confirmed diagnosis, any required prior treatments (with dates and outcomes), and clinical severity. If the exact criteria weren't included with your denial, request them in writing; your appeal then maps each requirement to the matching fact in your chart.

## Why UnitedHealthcare Denies Cognitive Rehabilitation as Not Medically Necessary

UnitedHealthcare (UHC) applies a structured medical-necessity review before approving cognitive rehabilitation services. Denials in this category most often occur when the submitted documentation does not clearly establish a qualifying neurological or acquired brain injury diagnosis, fails to demonstrate measurable functional deficits, or does not articulate why skilled rehabilitative services — rather than maintenance care or self-directed activity — are clinically required. UHC's coverage policy for cognitive rehabilitation typically requires evidence that the patient can reasonably be expected to make meaningful functional gains within a defined treatment window, so a plan of care that lacks specific, measurable goals is a common trigger for denial.

## Your Right to Appeal

Federal law gives you a layered appeal framework:

• Internal appeal: Submit a written first-level appeal within 180 days of the denial notice. UHC must respond within 30 days for prospective requests (60 days for post-service claims).
• External review (ACA §2719): If the internal appeal fails, you may request independent external review — typically within four months of the final internal denial. An accredited Independent Review Organization (IRO) that has no connection to UHC makes a binding decision, usually within 45 days (or as few as 72 hours for expedited/urgent cases).
• ERISA §503 (employer-sponsored plans): If your coverage is through an employer self-funded plan, you retain the right to a full-and-fair review and, ultimately, to pursue federal court action if the plan acts arbitrarily.

## Documentation to Gather

1. Diagnosis confirmation — neurologist, neuropsychologist, or treating physician records establishing the underlying condition (TBI, stroke, anoxic injury, post-COVID cognitive impairment, etc.) with ICD code. 2. Neuropsychological or standardized cognitive assessment — objective test results showing specific functional deficits in attention, memory, processing speed, or executive function. 3. Functional impact statement — documentation of how deficits limit activities of daily living, work, or safety. 4. Prior treatment history — dates and outcomes of any prior therapies or interventions already attempted. 5. Individualized plan of care — a therapist-authored document with measurable short- and long-term goals, treatment frequency, and expected duration. 6. Medical-necessity letter — a signed letter from the prescribing or referring clinician explicitly tying the patient's deficits to the proposed services and explaining why skilled care (not maintenance) is required.

## Mapping Your Case to UHC's Criteria

Request a copy of UHC's current published Coverage Determination Guideline for cognitive rehabilitation. For each criterion listed in that policy, note the exact chart entry that satisfies it. Present this as a table in your appeal: criterion on the left, supporting documentation reference on the right. Reviewers make faster favorable decisions when the mapping is explicit rather than implied.
