Cimt denied as not medically necessary by Cigna?

Cigna's specific coverage criteria for cimt 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 Cigna Denies CIMT as Not Medically Necessary — and Why You Can Appeal

Constraint-Induced Movement Therapy (CIMT) is an intensive, protocol-driven rehabilitation approach for upper-limb motor impairment, most commonly following stroke. When Cigna issues a medical-necessity denial, it is asserting that the clinical documentation submitted does not establish that CIMT is required for this patient — as opposed to elective, experimental, or merely convenient. This is one of the most common and most successfully overturned denial categories in rehabilitation care.

Medical-necessity denials for CIMT typically arise because the initial prior-authorization submission lacked sufficient functional assessment detail, did not address the specific criteria in Cigna's coverage policy, or did not explain why conventional occupational therapy was insufficient. A well-documented appeal that maps clinical evidence to each coverage criterion has a strong track record of reversal.

## Federal Appeal Rights

• Internal appeal (ERISA §503 / ACA): File within 180 days of denial. Cigna must respond within 60 days (30 days for pre-service).
• External review (ACA §2719): If the internal appeal is upheld, request independent external review within approximately 4 months. The external reviewer applies generally accepted clinical standards, not Cigna's internal criteria alone.
• Expedited review: Request within 72 hours if the condition is urgent or if delay would materially harm the patient's recovery trajectory.

## What to Gather

1. Functional deficit documentation: Standardized clinical measures of upper-limb function documented in the chart — the objective basis for the medical-necessity determination. The specific measures should align with those referenced in Cigna's coverage policy. 2. Diagnosis and etiology: Physician records confirming the underlying diagnosis, onset date, and neurological status. 3. Prior therapy outcomes: Records showing what conventional rehabilitation was tried, for how long, with what result — establishing that CIMT is clinically indicated as the next step. 4. Prescriber medical-necessity letter: A detailed letter from the treating physiatrist, neurologist, or occupational therapist stating: the clinical indication; why CIMT is medically necessary (not merely preferable); the expected functional outcome; and the consequence of non-treatment. 5. Cigna's published CIMT coverage policy: Identify each medical-necessity criterion. Build your appeal to address every one explicitly. 6. Rehabilitation potential: Documentation that the patient has sufficient motor function and cognitive capacity to benefit from intensive CIMT — a common coverage threshold.

## Criteria-Mapping Structure

| Cigna Medical-Necessity Criterion | Supporting Chart Documentation | |---|---| | Confirmed diagnosis and clinical indication | Physician notes, imaging, neurological exam | | Objective functional deficit in affected limb | Standardized assessment scores from chart | | Adequate rehabilitation potential | Therapist or physiatrist evaluation | | Prior conventional therapy tried/insufficient | Treatment records with dates and outcomes | | CIMT is appropriate for this stage post-onset | Prescriber letter addressing timing per guidelines |

The appeal letter should be structured as a point-by-point response to every criterion in the denial letter, supported by the corresponding chart documentation.
