Multidisciplinary Evaluation denied as non-formulary by Humana?

Humana's specific coverage criteria for multidisciplinary evaluation 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 Humana Denies a Multidisciplinary Evaluation as Non-Formulary — and What to Do

A non-formulary denial applied to a clinical service — rather than a drug — typically means the service is either excluded from the plan's covered-services schedule or requires a coverage exception before it is payable. For a multidisciplinary evaluation, this most often reflects a plan-design limitation or a benefits-administration error, because multidisciplinary evaluations are frequently covered under specialty visit or diagnostic evaluation benefits rather than a distinct formulary line.

## Why This Denial Is Worth Appealing

If the multidisciplinary evaluation is being billed under a procedure code that Humana's system does not map to a covered benefit category, the fix may be as simple as a coding clarification or a benefits-interpretation appeal. If Humana's plan genuinely excludes this service, the appeal should challenge whether the exclusion is consistent with the ACA's essential health benefits requirements (for non-grandfathered plans) and whether it creates a disparity under federal parity law for mental health or substance use disorder components of the evaluation.

## Your Federal Appeal Rights

• Internal appeal (ERISA §503 / ACA §2719): Request the specific plan exclusion or formulary provision Humana is relying on. You have the right to a full-and-fair review with access to the criteria used.
• External review (ACA §2719): After the internal appeal is exhausted or denied, request IRO review within approximately four months of the original denial. Expedited review is available when delay creates serious health risk.

## Appeal Timeline

1. Request the exact plan language Humana is relying on for the non-formulary determination, and confirm the procedure code(s) submitted. 2. Have the ordering provider or billing team verify whether an alternative billing pathway exists under covered specialty or diagnostic benefits. 3. Submit the internal appeal with the documentation below. 4. If denied, file for external IRO review within the statutory window.

## Documentation to Gather

• Benefits verification: A copy of the applicable Summary of Benefits and Coverage (SBC) and plan document confirming what specialty or diagnostic evaluation benefits are included.
• Procedure code documentation: Confirmation from the ordering provider of the procedure code(s) used and a written description of the service components.
• Medical-necessity letter: The ordering provider's letter explaining the clinical rationale, to support a coverage-exception request running alongside the benefits-interpretation appeal.
• ACA or parity argument: If applicable, a written statement that the service falls within essential health benefits or that excluding it creates a parity disparity.

## Criteria-Mapping Structure

Request Humana's coverage-exception criteria for services not on the covered-service schedule. Map each requirement to the chart facts and provider attestations supporting coverage. Submit alongside the benefits-interpretation argument as co-primary exhibits.
