TMS denied as not FDA-approved for this use by Humana?

Humana's specific coverage criteria for tms 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 Denied TMS as "Not FDA-Approved" — and Why That Denial Is Likely Wrong

Transcranial magnetic stimulation (TMS) carries FDA clearance for major depressive disorder (MDD) that has not responded adequately to antidepressant medication, and the agency has cleared additional indications since the original clearance. When Humana issues a "not FDA-approved" or "not FDA-cleared" denial for TMS, it most often reflects one of three documentation gaps: the ordering clinician did not specify the exact TMS device and cleared indication in the request; the claim was coded in a way that obscured the cleared indication; or Humana's reviewer applied a blanket "experimental" policy rather than checking current FDA clearance status.

## The Federal Appeal Framework

You have layered federal protections. Under ACA §2719 and its implementing regulations, non-grandfathered individual and small-group plans must follow an internal appeal process and then offer independent external review — the external-review window is generally available for roughly four months after the internal denial, though your plan documents control the exact deadline. Under ERISA §503, employer-sponsored plans must provide a full-and-fair review with written reasoning. Request the Summary Plan Description and Adverse Benefit Determination letter immediately; both are required to be provided to you.

An expedited appeal is available if your psychiatrist certifies that the standard timeline would seriously jeopardize your health or ability to function.

## What to Gather

• FDA clearance documentation. Your prescribing psychiatrist or the TMS device manufacturer can supply the FDA 510(k) clearance letter for the specific device to be used. Attach it directly to your appeal.
• Diagnosis confirmation. A formal psychiatric diagnosis from your chart, consistent with the cleared indication.
• Prior treatment history. Dated records of every antidepressant medication trial — name, duration, dose range, and documented reason for discontinuation or inadequate response. This establishes the "treatment-resistant" profile the clearance contemplates.
• Prescriber medical-necessity letter. A signed letter from your psychiatrist explaining why TMS is appropriate for your specific case, citing the cleared indication and your response history.
• Humana's own coverage policy. Request Humana's current Medical Coverage Policy for TMS by name. Read each coverage criterion; your appeal should map your chart facts to every requirement listed.

## Criteria-Mapping Structure

Build a table for your appeal letter with three columns: (1) Humana's stated requirement, (2) the FDA clearance language or your chart fact that satisfies it, and (3) the supporting document and page number. Every requirement in the denial letter and in Humana's published policy should have a corresponding answer. Unexplained gaps are the most common reason appeals fail.

## Next Step

File the internal appeal in writing within Humana's stated deadline (check your denial letter). Attach the FDA clearance letter, the criteria-mapping table, and your prescriber's letter. If the internal appeal is denied, invoke external review in writing before the roughly four-month window closes.
