Medicare Advantage Denials & Appeals

This is one of the most common — and most successfully appealed — denials in Medicare Advantage. Federal investigators have found that when patients appeal denied inpatient rehabilitation facility (IRF) admissions, plans overturn their own decision in a large share of cases, sometimes the majority, at some plans.

The first step is requesting the denial in writing if you haven't already — you need the specific stated reason before you can build an effective appeal. Ask your physician to document both the current functional needs and the risks of stepping down to a lower level of care instead of inpatient rehab.

Skilled nursing facility denials and early discharge notices are common after a hospital stay, especially for rehabilitation following surgery, a fall, or an illness. If the facility or your plan says coverage is ending, you should receive a written Notice of Medicare Non-Coverage (NOMNC) explaining your right to an expedited appeal — this appeal can often be filed the same day, with a decision typically within 24-72 hours.

Don't let care end while you're deciding whether to appeal — request the expedited review immediately if you disagree with the discharge date.

A rushed hospital discharge is one of the most time-sensitive situations in Medicare Advantage. You have the right to request a fast (expedited) appeal through the Quality Improvement Organization (QIO) for your state, and the hospital cannot bill you for the extra days while that appeal is pending, as long as you file before the deadline on your discharge notice.

Ask the discharge planner or charge nurse for your Important Message from Medicare (IM) or equivalent notice — it has the phone number and deadline for the fast appeal.

Prior authorization denials happen before a service is delivered, and they're one of the most frequently overturned decision types when appealed. Federal audits have repeatedly found that a meaningful share of denied prior authorization requests actually met Medicare's own coverage criteria and should not have been denied in the first place.

Ask your plan for the specific denial reason in writing, and ask your doctor's office to request a peer-to-peer review with the plan's medical director — this can resolve some denials without a formal written appeal at all.

Imaging denials are often tied to prior authorization or "not medically necessary" determinations. Your doctor's office typically has the clearest path to resolving this quickly, since they can supply the clinical documentation the plan is asking for, or request a peer-to-peer conversation with the plan's reviewing physician.

If the denial letter cites a specific medical policy or guideline, ask your doctor's office to address that guideline directly in any resubmission or appeal.

Medication denials usually come with a specific reason — step therapy requirements, a preferred alternative on the plan's formulary, or a request for prior authorization. Your prescribing doctor can often request a formulary exception, explaining why the specific medication is medically necessary compared to plan alternatives.

If you need the medication urgently, ask about an expedited coverage determination, which plans must generally decide on a faster timeline than a standard request.

Home health denials often relate to whether the plan considers you "homebound" under Medicare's definition, or whether the requested services are considered skilled care. Ask the home health agency for the specific denial reason, and ask your physician to document why skilled services (not just personal care) are medically necessary in your specific situation.

Start by checking your mail and any online plan portal for a written denial letter — Medicare Advantage plans are required to provide one when they deny a claim or request. If you haven't received one within a few days of being told about the denial, call the number on your plan ID card and ask them to send the written denial notice.

Once you have it in hand, it will state the specific reason and your appeal rights and deadline.

Medicare Advantage (sometimes called "managed Medicare" or "Medicare Part C") is administered by private insurance companies under contract with Medicare, and each plan makes its own coverage and prior authorization decisions — which is why denial and appeal processes can look different from Original Medicare (Parts A and B), which is administered directly by the federal government.

Medicare Advantage plans are required to offer an appeal process with defined deadlines, similar in spirit to Original Medicare's process but run through the plan itself, with escalation rights to an independent reviewer if the plan upholds its own denial.

Standard Medicare Advantage appeal deadlines are typically 60 days from the date of the denial notice, though expedited situations (like a discharge dispute) can be much shorter. If you've missed a standard deadline, you can still ask your plan whether they'll accept a late appeal for good cause (for example, if you never actually received the denial notice) — plans have discretion to allow this in some circumstances.

A free SHIP (State Health Insurance Assistance Program) counselor can help you understand your options if you're past a deadline.

An expedited appeal is available when waiting for a standard decision could seriously jeopardize your health, ability to regain maximum function, or ability to function overall. This applies especially to hospital discharge disputes and ongoing care denials (like SNF or IRF stays). Ask your plan directly for an expedited appeal, and ask your doctor to support the request in writing if possible — doctor support can strengthen the case for urgency.

Expedited appeals generally must be decided much faster than standard appeals, often within 72 hours.
