CPAP APAP denied for failing step 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 Denied Your CPAP/APAP Under "Step Therapy" — and How to Appeal

Step therapy (also called "fail-first") denials for CPAP/APAP are unusual because these devices are generally the first-line, guideline-supported treatment for obstructive sleep apnea — they are not typically positioned as a second-step therapy. When Humana invokes step therapy in the CPAP/APAP context, it usually means the plan is requiring documentation that conservative or positional interventions were tried first, or that a standard CPAP was trialed before an APAP was approved, or that the clinical pathway for OSA diagnosis was not followed in the documented order (sleep study before device dispensing).

## Why This Denial Is Appealable

Step-therapy protocols must be clinically appropriate and evidence-based. For OSA, the applicable professional society guidelines — including those from the American Academy of Sleep Medicine (AASM) — support CPAP or APAP as primary therapy, not a second-line option. If Humana's step requirement is not consistent with current clinical guidelines, that is a valid ground for appeal. Many states also have step-therapy override laws; check whether yours applies to your plan type.

## Federal Appeal Framework

• ERISA §503: Employer-sponsored plan members have the right to a full-and-fair review. The appeal must be decided by someone who was not involved in the original denial and who has relevant clinical expertise.
• ACA §2719 / External Review: After exhausting internal appeals, you may request independent external review within approximately four months of the final denial notice. Verify the exact window on your denial letter.
• Expedited review: If you have an urgent medical need (e.g., documented severe OSA affecting your ability to function or work), request expedited review.
• State step-therapy override laws: Many states require insurers to grant step-therapy exceptions when the required first step is contraindicated, previously failed, or clinically inappropriate. Confirm your plan type (fully-insured vs. self-funded ERISA) to know which state laws apply.

## Concrete Appeal Steps and Timeline

1. Obtain Humana's step-therapy or coverage criteria for CPAP/APAP — identify exactly which "step" is claimed to be missing. 2. Gather evidence showing that the required prior step was either completed, clinically contraindicated, or not required by current clinical guidelines. 3. Have your prescriber draft a step-therapy exception letter that references the relevant guideline organization (e.g., AASM) without stating specific numbers, and explains why the ordered device is the clinically appropriate treatment. 4. File the Level 1 internal appeal within the deadline on the denial letter (typically 180 days from denial). 5. If denied, escalate to Level 2 internal review (if offered) and then external review within four months of final denial.

## Documentation to Gather

• Diagnosis documentation: Sleep study confirming OSA and any prior diagnostic workup.
• Treatment history: Dates and outcomes of any prior interventions (positional therapy, weight-loss counseling, oral appliance evaluation) — even if brief, document them.
• Prescriber medical-necessity letter: Explains why CPAP/APAP is the appropriate first-line device for this patient and why any required prior step either was completed or is clinically inappropriate.
• Guideline reference: A general reference to the applicable professional society recommendation (e.g., AASM) supporting CPAP/APAP as primary therapy, without quoting specific statistics.

## Criteria-Mapping Structure

List each step-therapy criterion from Humana's policy. For each step, either (a) cite the chart record showing that step was completed, or (b) cite the prescriber's explanation of why that step is not clinically applicable. An IRO reviewer will look for this structure to confirm that the step protocol was addressed item by item.
