A parent generally has 65 days from the date on the Medicare Advantage denial notice to file a Level 1 reconsideration, according to CMS. The underlying regulation sets the deadline at 60 calendar days after receipt of the notice, and because receipt is presumed 5 days after the notice date, CMS states the deadline operationally as 65 days from the notice date. Both framings are correct; the consumer-facing shorthand is 65 days from the notice date.

How Long Does a Parent Have to Appeal a Medicare Advantage Denial? (2026)
By Chuck Brodsky, Co-Founder, MediNav — Updated July 2026 — 6 min read
Quick answer
If a Medicare Advantage plan has denied your parent's care, the clock starts the moment that notice is dated. Missing the window can end an appeal before it begins, so the single most important thing a caregiver can do is note the notice date and count forward.
The deadline, stated two ways
The federal rule at 42 CFR 422.582(b) gives a parent 60 calendar days after receiving the denial notice to request a Level 1 reconsideration. Medicare presumes the notice is received 5 days after its date unless there is evidence otherwise. Adding that 5-day mail presumption to the 60-day window is why CMS describes the deadline as 65 days from the notice date. Use the notice date on the letter, count 65 days, and treat that as the deadline.
Standard versus expedited appeals
Not every appeal runs on the same decision timeline. For a standard pre-service request, the plan must decide within 30 days. If waiting could seriously jeopardize your parent's health, you can request an expedited appeal, and the plan must decide within 72 hours. Payment appeals — where the service already happened and the dispute is about paying for it — are decided within 60 days, and standard Part B drug appeals within 7 days. The filing deadline is the same 65-day window; these figures are how long the plan then has to respond.
Do not talk yourself out of the 60-day rule
You may see both "60 days" and "65 days" cited, and it can look like a contradiction. It is not. The 60 days is the regulatory text, measured from receipt; the 65 days folds in the 5-day mail presumption and is measured from the notice date. If you file within 65 days of the date printed on the notice, you are within the deadline. When in doubt, file earlier.
If the deadline has already passed
A late appeal can still be accepted if your parent shows good cause for missing the deadline — for example, a serious illness or not receiving the notice. Good cause is decided case by case, so if the window has closed, file anyway with a short explanation of why it was late rather than assuming the appeal is lost.
How a caregiver should handle the clock
The moment a denial arrives, write the notice date and the 65-day deadline on the letter and in your calendar. Request the denial rationale in writing, ask the ordering physician for a letter of medical necessity, and file the Level 1 reconsideration through the plan. The appeals hub walks through each step.

Frequently asked questions
What if my parent's denial notice is already a few weeks old?
Count 65 days from the date printed on the notice. If you are still within that window, file the Level 1 reconsideration now. If it has passed, you can still file with a good-cause explanation for the delay — good cause is evaluated case by case, so do not assume the appeal is lost.
Is the deadline 60 days or 65 days?
Both are correct. The regulation gives 60 calendar days from receipt of the notice; Medicare presumes receipt 5 days after the notice date, so the deadline is 65 days from the notice date. Filing within 65 days of the printed date keeps your parent within the window.
How fast must the plan decide?
For a standard pre-service appeal, within 30 days. For an expedited appeal, when your parent's health could be seriously harmed by waiting, within 72 hours. Payment appeals are decided within 60 days and standard Part B drug appeals within 7 days.
When should I request an expedited appeal?
When waiting for a standard decision could seriously jeopardize your parent's health or ability to regain function. In that case the plan must decide within 72 hours. A physician's supporting statement strengthens the request for expedited handling.
Does the filing deadline change for a payment appeal?
No. The filing window is the same 65 days from the notice date. What differs is the plan's decision timeline: payment appeals are decided within 60 days, compared with 30 days for a standard pre-service appeal.
Where do I file the appeal?
With your parent's Medicare Advantage plan — the denial notice explains how and includes the address or portal. The appeals hub provides a step-by-step walkthrough, including what documents to gather before filing the Level 1 reconsideration.
