Start with the notice
Every denial comes in writing and says how to appeal and by when. Original Medicare denials appear on the Medicare Summary Notice, mailed every four months if you had services and available sooner in your Medicare.gov account. Medicare Advantage and Part D plans send their own written notice. In July 2026, 3,051,948 of Florida's 5,344,538 people with Medicare were in Medicare Advantage, so for most Floridians the first appeal goes to the plan.
How to file the first appeal
- Read why it was denied. A missing prior authorization, a coding error or a "not medically necessary" finding each needs a different answer.
- Get your doctor's support. Ask for a letter or records explaining why you need the service or drug.
- File by the deadline. Original Medicare: a redetermination request within 120 days, sent to the contractor named on the notice. Medicare Advantage: a reconsideration within 65 days. Part D: a redetermination within 65 days.
- Keep copies. Note who you spoke with and when.
- Read the decision. If you lose, the letter tells you how to go to the next level.
The five levels
| Level | Original Medicare | Medicare Advantage | Part D |
|---|---|---|---|
| 1 | Redetermination by the claims contractor | Reconsideration by the plan | Redetermination by the plan |
| 2 | Qualified Independent Contractor (within 180 days) | Independent Review Entity (sent automatically) | Independent Review Entity (you ask, within 60 days) |
| 3 to 5 | Office of Medicare Hearings and Appeals, the Medicare Appeals Council, then federal court; levels 3 and 5 need a minimum amount in dispute that Medicare sets each year | ||
Florida points
- Medicare and Medicaid together: some Florida D-SNPs, including the FIDE plans that also carry Medicaid long-term care, are "applicable integrated plans" under federal rules. They use one combined process: you have 60 days to ask the plan for an integrated reconsideration, which it decides within 30 days, or 72 hours if fast. In other plans, Medicare and Medicaid are appealed separately. See D-SNPs in Florida.
- Florida Medicaid denials: if you're in a Medicaid plan, finish the plan's appeal first, then ask AHCA for a Medicaid fair hearing through its Medicaid Helpline, 1-877-254-1055. Eligibility problems go to DCF.
- Medigap: a Medigap policy generally pays its share only after Medicare approves an Original Medicare claim, so appeal to Medicare first. Problems with the Medigap insurer itself go to DFS.
- Questions about the process: call 1-800-MEDICARE (1-800-633-4227, TTY 1-877-486-2048).

Frequently asked questions
Can my doctor appeal for me?
Yes. For a Medicare Advantage service denial or a Part D drug denial, your doctor or prescriber can request the appeal for you. For anyone else, such as a family member, name them on Medicare's Appointment of Representative form (CMS-1696).
What if waiting could harm my health?
Ask for a fast (expedited) appeal. A Medicare Advantage or Part D plan must then decide within 72 hours if it agrees, or your doctor says, that waiting could seriously jeopardize your health.
Can Florida's Department of Financial Services help with a Medicare denial?
Not with a Medicare Advantage or Part D decision: DFS says CMS has jurisdiction over Medicare plans. DFS does take complaints about Medigap insurers and insurance agents, by phone at 1-877-693-5236 or through its Consumer Assistance Portal.
Who do I call for a hospital discharge?
That's a different, faster appeal. Call Acentra Health, the Medicare quality improvement organization serving Florida, at 1-888-317-0751 (TTY 711), no later than your planned discharge day.
