CPAP APAP denied as duplicate or overlapping therapy 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 Issues a Duplicate-Therapy Denial for CPAP/APAP

Humana's duplicate-therapy denial for PAP equipment usually means the plan's records show that a CPAP or APAP device was previously authorized or dispensed within the same benefit period, and the new claim or request appears to be for the same type of equipment. Common root causes include: an active authorization that has not been closed out, a prior device that was not formally discontinued in Humana's system, a billing error where the same claim was submitted twice, or a situation where a new device is needed but the clinical rationale for replacement has not been communicated.

This denial is administrative in nature and is generally resolvable — either by correcting the billing record or by documenting the clinical reason a new device is needed while a prior authorization remains on file.

## Federal Appeal Rights

• ERISA §503 (self-funded employer plans): full-and-fair internal review with written denial reasons.
• ACA §2719 (fully insured plans): independent external review by an accredited IRO after internal exhaustion.
• External-review window: approximately four months from the denial notice — verify the exact deadline on your letter.
• Expedited review: available if the standard timeline would seriously jeopardize your health.

## Concrete Appeal Process

1. Obtain the denial notice and confirm whether Humana is citing an active prior authorization, a prior paid claim, or a duplicate claim submission. 2. Contact your DME supplier to verify that no duplicate claim was submitted in error. 3. If a prior authorization is still active, request Humana's records showing the prior auth details and compare them to your current need. 4. Document the clinical or factual distinction between the prior authorization and the current request. 5. File the internal appeal with corrected billing documentation or clinical justification for a second device within the same period. 6. If denied internally, escalate to external review.

## Documentation to Gather

• Prior authorization history: records from Humana or your DME supplier showing when the previous device was authorized and dispensed.
• Device status documentation: evidence that the prior device is no longer in service — equipment return receipt, repair assessment showing the device is irreparable, or prescriber note documenting device discontinuation.
• Clinical justification for new device: if the new request is for a different device type (e.g., upgrading from CPAP to APAP for clinical reasons), the prescriber's explanation of the clinical distinction.
• Corrected claim (if billing error): a statement from the DME supplier confirming the duplicate was a submission error and providing a corrected claim.
• Prescriber letter: addressing why the current request is not duplicative of any prior authorization.

## Criteria-Mapping Structure

Differentiate the current request from the prior authorization:

| Basis for Duplicate Finding | Rebuttal Evidence | |---|---| | Prior authorization still active | Documentation that prior device is discontinued or returned | | Same device type claimed twice | Clinical rationale for new device (failure, upgrade, loss) | | Duplicate claim submission | Corrected claim from DME supplier | | Overlap in authorization period | Timeline showing gap between prior and current need |

If Humana's records are simply outdated, a direct call to the provider services line to close the prior authorization — documented in writing — can sometimes resolve the denial before a formal appeal is needed. Always follow up any phone resolution with a written confirmation request.
