CPAP APAP denied for missing prior authorization by Humana?

Humana's specific coverage criteria for cpap apap 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 Your CPAP/APAP for "Prior Authorization Required" — and How to Appeal

A prior authorization (PA) denial means the device was furnished or ordered before Humana approved it, or the PA process was not completed correctly. This is one of the most common — and most reversible — CPAP/APAP denials. Humana requires PA for DME including CPAP and APAP to confirm that coverage criteria are met before the device is dispensed.

## Why This Denial Is Appealable

PA denials can be overturned in two ways: (1) retroactive authorization, where you show that all coverage criteria were met at the time of service even though the PA step was skipped; or (2) prospective authorization for ongoing use. Courts and regulators have repeatedly held that a procedural failure — not obtaining PA — does not automatically mean the service was not medically necessary.

## Federal Appeal Framework

• ERISA §503 (employer plans): Full-and-fair internal review with a written criteria-based decision.
• ACA §2719 / External Review: After your final internal denial, you have approximately four months to file with an independent IRO. Check the denial letter for the precise deadline.
• Expedited review: Available if you are currently using the device and interruption would cause serious harm — document the clinical urgency explicitly.

## Concrete Appeal Steps and Timeline

1. Check whether a PA was submitted but denied on technical grounds, or whether it was never submitted. If a PA was never filed, ask your prescriber to file one immediately and request retroactive review. 2. Obtain Humana's current CPAP/APAP prior authorization criteria from the Humana provider portal or by calling the number on your Explanation of Benefits (EOB). 3. Submit your Level 1 internal appeal with all supporting documentation by the deadline on your denial letter (commonly 180 days from denial). 4. If denied at Level 1, file a Level 2 internal appeal (if available) and then external review within four months of final denial.

## Documentation to Gather

• Sleep study results: The original polysomnogram or home sleep apnea test, with the interpreting physician's signature and OSA diagnosis.
• Prescriber order: A written order from a licensed provider specifying the device type, clinical indication, and date of order.
• PA submission records: Any reference numbers, fax confirmations, or portal submissions showing a PA was attempted.
• Medical-necessity letter: Your prescribing physician's letter confirming the OSA diagnosis, the clinical rationale for CPAP or APAP specifically, and the date treatment became necessary.
• Timeline documentation: Dates of diagnosis, sleep study, prescriber order, device dispensing, and any PA requests — present these in chronological order.

## Criteria-Mapping Structure

Obtain Humana's PA criteria document. List each requirement in a table. In the column beside each requirement, cite the specific page and exhibit in your appeal packet that satisfies it. This structure shows the reviewer exactly where to look, reducing the chance of a summary denial. End with a clear statement that all criteria were met as of the service date and that denial on procedural grounds alone is not a valid basis for withholding a medically necessary device.
