Medicare Appeals and Coverage Decisions

Medicare Appeals: What Decisions Can You Appeal?

Direct answer

You can generally appeal a Medicare coverage or payment decision you disagree with. This includes decisions by Original Medicare, a Medicare Advantage or other Medicare health plan, or a Medicare drug plan. Appealable decisions may involve denied services, supplies, items, prescriptions, payment requests, reduced payments, or decisions to stop covering care you believe should continue.

What Medicare decisions are appealable?

A Medicare appeal is used when you disagree with a decision about whether Medicare or your plan will cover or pay for something. Depending on your coverage, you may be able to appeal decisions involving:

  • A service, supply, item, or prescription drug that Medicare or your plan says is not covered.
  • A request for payment that Medicare or your plan denies.
  • A decision to pay less than you believe Medicare or the plan should pay.
  • A decision to stop providing or paying for all or part of care you believe you still need.
  • Certain Medicare drug plan decisions, including coverage determinations and some drug management program decisions.

Can you appeal Original Medicare decisions?

Yes. In Original Medicare, appeal rights usually begin after Medicare makes a coverage or payment decision on a claim. The decision is listed on your Medicare Summary Notice, often called an MSN.

You can appeal items or services listed on the MSN if you believe Medicare should have covered them or paid more. Medicare.gov says you must file by the deadline shown on the MSN, although you may still be able to file late if you can show good cause.

Can you appeal Medicare Advantage plan decisions?

Yes. In a Medicare Advantage Plan, coverage decisions are called organization determinations. These decisions can address whether a service, drug, or supply is covered and what the plan will pay.

If the plan gives an unfavorable initial decision, you or your representative can usually ask the plan to reconsider. Medicare.gov refers to this first level of appeal as a Health Plan Reconsideration. The plan’s written decision should explain how to appeal and the deadline for doing so.

Can you appeal Medicare drug plan decisions?

Yes. In a Medicare drug plan, an initial drug coverage decision is called a coverage determination. If you disagree with that decision, you, your representative, or your prescriber can ask for a redetermination.

Examples may include a plan refusing to cover a drug, denying an exception request, deciding that prior authorization or another utilization management rule has not been met, or denying payment for a covered drug. If an exception is requested, the prescriber generally must explain the medical reason for the exception.

Can you appeal if Medicare-covered care is ending too soon?

Yes, in certain situations you may have the right to a fast appeal if you believe Medicare-covered services are ending too soon. This can apply to settings such as a hospital, skilled nursing facility, home health agency, hospice, or comprehensive outpatient rehabilitation facility, depending on the notice you receive and your coverage.

Fast appeal rules are time-sensitive. The notice you receive should explain who to contact and by when. If you continue services after the coverage end date, you may be responsible for costs unless the appeal decision is in your favor.

What is not handled as a Medicare appeal?

Not every Medicare problem is an appeal. If your concern is about the quality of care, customer service, waiting times, disrespectful treatment, or another service problem, Medicare generally treats that as a complaint or grievance, not a coverage appeal.

Also, an Advance Beneficiary Notice, or ABN, is not by itself an official Medicare denial. If a claim is later submitted and Medicare denies payment, that denial may give you appeal rights.

Our Process

From First Meeting to Medicare Enrollment

We begin by helping you understand how Medicare works and how the different pieces fit together. We walk through Original Medicare, Parts A and B, Medicare Advantage, Medicare Supplement insurance, and Part D prescription drug coverage, including how formularies, drug tiers, and plan rules can affect your costs.

We also explain dental, vision, and hearing coverage, along with other products that may help fill gaps in your healthcare plan. Depending on your needs, that may include short-term in-home healthcare coverage, hospital indemnity insurance, or coverage designed to provide additional financial support following a cancer diagnosis, heart attack, or stroke.

Once you understand the landscape, we move into the planning stage. That is when we review your doctors, hospitals, prescription drugs, current coverage, and other personal details so we can begin evaluating the Medicare plan options that fit your situation.

Discovery Meeting
We collect information about your doctors, hospitals, prescription drugs, current coverage, and other important details, then discuss your unique situation and priorities. Start your secure Medicare profile.
Create Your Strategy
We review the information gathered during discovery and develop a Medicare claiming and coverage strategy tailored to your circumstances.
Plan Enrollment
Once you are comfortable with the strategy, we help coordinate the appropriate enrollment steps and timing.
Annual Reviews
Medicare plans, costs, formularies, provider networks, and personal circumstances can change. We conduct annual reviews to help determine whether your current coverage still fits.
