Medicare denied your CPAP and equipment? What to do next

Why Medicare (Original + Advantage) denies CPAP and medical equipment

Medicare is a federal program with two delivery modes, Original (fee-for-service Part A/B + Part D drug plans) and Advantage (private MA-C plans). Each has its own appeal ladder, and rights are stronger than most beneficiaries realize.

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 Medicare (Original + Advantage) 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 Medicare (Original + Advantage) 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 Medicare (Original + Advantage) appeal process

Appeal levels: 5 federal levels. Each has its own deadline and a minimum dollar threshold for the higher levels (ALJ requires $200+ in 2026).

Carrier timing: 120 days from denial for level 1 (Original) or 60 days for Medicare Advantage. Each subsequent level: 60 days.

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).

Common Medicare (Original + Advantage) denial patterns for CPAP and medical equipment

Original Medicare: 5-level appeal. Redetermination by MAC → reconsideration by QIC → ALJ hearing → Medicare Appeals Council → federal district court. The QIC and ALJ levels reverse a substantial share of denials when properly briefed.
Medicare Advantage: identical 5-level ladder. MA plans must follow the same federal appeal structure as Original Medicare. Plan-level reconsideration → Independent Review Entity (Maximus) → ALJ → Council → federal court.
Part D drug coverage denials. Part D appeals follow a separate but parallel ladder. Tiering exceptions and formulary exceptions are filed before a coverage determination challenge.

How to win your Medicare (Original + Advantage) 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 Medicare (Original + Advantage), that strategy rides on this procedural spine:

Procedural-rights anchor. Every Medicare (Original + Advantage) 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. Medicare (Original + Advantage) 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 Medicare (Original + Advantage)'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.

Medicare (Original + Advantage) CPAP and medical equipment appeals: frequently asked questions

Medicare (Original + Advantage) 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 Medicare (Original + Advantage) 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 Medicare (Original + Advantage) 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 Medicare (Original + Advantage)?

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.
