Ambetter denied your CPAP and equipment? What to do next

Why Centene / Ambetter denies CPAP and medical equipment

Centene operates one of the largest Medicaid footprints in the U.S. and sells ACA marketplace coverage under the Ambetter brand. Marketplace plans drew elevated regulator and journalist scrutiny in 2024 for higher-than-average denial rates on in-network claims, and Centene-managed Medicaid lines vary plan-by-plan by state.

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 Centene / Ambetter 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 Centene / Ambetter 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 Centene / Ambetter appeal process

Appeal levels: Marketplace: internal appeal then federal external review (IRO). Medicaid: plan appeal then state fair hearing. Medicare Advantage: federal 5-level ladder.

Carrier timing: 180 days from denial for marketplace internal appeals; 4 months / 120 days for federal external review. Medicaid fair-hearing deadlines vary by state, often as short as 90-120 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).

What we know about Centene / Ambetter: We confirm the specific Centene subsidiary (Ambetter, Sunshine Health, Wellcare, etc.) before filing, because procedural rules and the supervising regulator change with the line of business.

Common Centene / Ambetter denial patterns for CPAP and medical equipment

ACA marketplace in-network denials. Ambetter marketplace plans have been documented denying in-network medical claims at rates above the marketplace average. Federal ACA rules guarantee internal appeal plus external review via an Independent Review Organization (IRO), both are no-cost to the member.
Narrow networks driving care-access denials. Ambetter HMO products often run narrower networks than the local competition. Network-adequacy challenges (state DOI complaints citing inadequate specialist access) can convert an out-of-network denial into in-network coverage.
Medicaid managed care fair hearings. Centene-managed Medicaid plans (Sunshine Health, Buckeye, Peach State, etc.) operate under each state's Medicaid rules. After plan-level appeal, members have the right to a state fair hearing, a binding administrative process with strong reversal history.

How to win your Centene / Ambetter 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 Centene / Ambetter, that strategy rides on this procedural spine:

Procedural-rights anchor. Every Centene / Ambetter 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. Centene / Ambetter 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 Centene / Ambetter'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.

Centene / Ambetter CPAP and medical equipment appeals: frequently asked questions

Centene / Ambetter 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 Centene / Ambetter 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 Centene / Ambetter 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 Centene / Ambetter?

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.
