Humana denied your CPAP and equipment? What to do next

Why Humana denies CPAP and medical equipment

Humana is among the top three Medicare Advantage carriers and also operates Tricare and a smaller commercial book. Medicare Advantage prior auth is the highest-volume denial category.

For CPAP and medical equipment specifically: CPAP and BiPAP machines, oxygen, power wheelchairs, hospital beds, and other durable medical equipment are denied for missing documentation, unmet usage requirements, or supplier problems. The rules are specific and the fix is usually paperwork.

The law that controls this appeal

Medicare covers CPAP for obstructive sleep apnea under National Coverage Determination 240.4 after a qualifying sleep study, with continued coverage after the first 90 days only if adherence is documented (use of at least 4 hours a night on 70 percent of nights in a consecutive 30-day period) and the physician documents benefit. Other equipment follows Medicare's DME rules (42 CFR 410.38) and supplier standards. Medicare Advantage plans must follow Medicare coverage rules (42 CFR 422.101(b)). Commercial plans apply their own equipment policies, which must be disclosed on request.

What Humana denies for CPAP and medical equipment

The CPAP and medical equipment services most often denied:

CPAP or BiPAP after a home sleep test
Continued CPAP rental after the 90-day compliance period
Power wheelchairs and scooters
Home oxygen
Hospital beds, lifts, and continuous glucose monitors

Why CPAP and medical equipment claims get denied

A typical Humana CPAP and medical equipment denial almost always cites one of these reasons. Each one maps to a specific rebuttal in the appeal:

Sleep study does not show the apnea index the policy requires
Compliance data from the device does not meet the usage threshold
Face-to-face visit or written order missing or undated
Supplier not enrolled or item not on the plan's approved list
Plan says a less costly item meets the need

The Humana appeal process

Appeal levels: Medicare Advantage federal 5-level ladder. Commercial: internal then external review.

Carrier timing: Medicare Advantage: 60 days between each level. Commercial: 180 days from denial for internal; generally at least 4 months (120 days) for federal external review (varies by plan and state).

CPAP and equipment timing: Internal appeal: at least 180 days to file for commercial and employer plans; pre-service decisions within 30 days (29 CFR 2560.503-1). Medicare Advantage: 65 days to request reconsideration (42 CFR 422.582). Traditional Medicare: 120 days to request redetermination of a claim (42 CFR 405.942).

What we know about Humana: Humana cases benefit most from level-2 (Maximus) escalation. We don't stop at level 1.

Common Humana denial patterns for CPAP and medical equipment

Five-level Medicare appeal process. Humana Medicare Advantage denials enter the federal appeal ladder: plan reconsideration → IRE (Maximus) → ALJ → Medicare Appeals Council → federal court. Federal data show Medicare Advantage plans overturn a large share of denials once they are appealed, yet very few members appeal; reversal odds stay meaningful through the IRE and ALJ levels.
DME (durable medical equipment) denials. Humana DME denials often cite missing home-evaluation documentation. Re-filing with the home-evaluation packet attached is the most common reversal path.
Skilled nursing and post-acute care. Humana has been the subject of CMS audits on early termination of skilled nursing coverage. Appeals citing CMS coverage manual standards have a documented success record.

How to win your Humana CPAP and medical equipment appeal

Strategy for CPAP and medical equipment: Get the sleep study report, the physician's order, and the device compliance download. Match each to the policy's requirements. If compliance fell short because of mask fit or side effects, have the physician document the intervention and request a new compliance period. For mobility equipment, the face-to-face evaluation must describe the functional limitation in the home. Ask the plan for its equipment policy and the reviewer's credentials.

Filed against Humana, that strategy rides on this procedural spine:

Procedural-rights anchor. Every Humana denial triggers ERISA § 503 or 45 C.F.R. § 147.136 procedural rights. The cover letter invokes these in the opening paragraph to lock the timeline and force criteria disclosure.
Criteria-disclosure demand. Humana frequently denies on "not medically necessary" without disclosing the clinical criteria applied. Once disclosed, those criteria become the rebuttal map.
Controlling-standard citation. Medicare covers CPAP for obstructive sleep apnea under National Coverage Determination 240.4 after a qualifying sleep study, with continued coverage after the first 90 days only if adherence is documented (use of at least 4 hours a night on 70 percent of nights in a consecutive 30-day period) and the physician documents benefit. Other equipment follows Medicare's DME rules (42 CFR 410.38) and supplier standards. Medicare Advantage plans must follow Medicare coverage rules (42 CFR 422.101(b)). Commercial plans apply their own equipment policies, which must be disclosed on request.
Treating-provider attestation. A letter from the treating physician addressing each criterion in Humana's own policy language. This is the single strongest evidentiary element.
Requested action. A specific demand to reverse the CPAP and medical equipment denial and approve the service, not a general "please reconsider."

What a CPAP and medical equipment appeal can recover

Typical recovery for CPAP and medical equipment cases runs Equipment is billed as a purchase or a monthly rental; a denied device or a denied rental period is commonly hundreds to a few thousand dollars at billed charges, and higher for power mobility and oxygen.. The exact figure depends on the specific service and your plan's contracted rates.

Humana CPAP and medical equipment appeals: frequently asked questions

Humana stopped paying for my CPAP after 90 days. Why?

Continued coverage typically depends on documented adherence during the first 90 days plus a physician note that the device is helping. If usage fell short, the physician can document the reason and the fix, and the plan can be asked for a new compliance period.

My home sleep test showed apnea but Humana denied the machine. What is missing?

Usually the index threshold in the policy, the physician's face-to-face note, or a written order with the required elements. Request the policy and compare it to your report.

Does Humana have to follow Medicare's equipment rules?

Medicare Advantage plans may not use coverage criteria more restrictive than traditional Medicare's. Commercial plans set their own, which you can request in writing.

The supplier says the claim was denied, not the doctor. Who appeals Humana?

Either can, and the patient's member appeal carries the patient's own rights, including external or independent review. Ask the supplier for the denial and the claim details.
