Medicare Appeal Deadline Calculator

The Medicare appeals process is built as a strict ladder: five distinct levels, each with its own filing deadline, and each level only reachable after receiving an unfavorable decision at the level before it. Missing any single deadline along the way doesn't just delay that step — with very limited exceptions for documented good cause, it forfeits the right to continue the appeal at all, which makes understanding exactly how much time you have at each step one of the most consequential pieces of Medicare paperwork most beneficiaries will ever deal with.

Level 1, redetermination, gives the most generous initial window: 120 days from the date on the original denial notice to file. This is a review by the same Medicare Administrative Contractor that made the initial decision, essentially asking them to reconsider — and it typically takes up to 60 days for a decision once filed. If that redetermination comes back unfavorable, Level 2 (reconsideration) hands the case to an independent Qualified Independent Contractor, with a notably longer 180-day filing window — the only point in the entire five-level process where the deadline extends rather than tightens.

From there, the deadlines compress and stay compressed: Level 3 (a hearing before an Administrative Law Judge), Level 4 (review by the Medicare Appeals Council), and Level 5 (federal district court) each give just 60 days to file from the prior level's decision. Levels 3 and 5 add a second, separate requirement beyond the deadline — a minimum dollar amount actually in dispute ($200 for Level 3, $1,960 for Level 5 in 2026) — meaning a case can be timely filed and still not qualify for that level if the dollar amount at stake falls under the threshold.

What makes this process genuinely difficult to navigate isn't any single deadline in isolation — 60 or 120 days is a workable window on its own — it's that each successive appeal typically requires more substantial documentation than the last, at exactly the point where the clock is often tightest. Gathering medical records, provider statements, or billing documentation for a Level 3 hearing within 60 days is a meaningfully bigger task than the more procedural Level 1 redetermination request, which is exactly why starting to prepare immediately upon receiving each decision — rather than waiting to see how much time is left — matters more at each successive level, not less.

The strictness of these deadlines is deliberate, not incidental: Medicare's appeals system processes an enormous volume of cases, and firm, non-negotiable timelines are part of how that volume stays manageable for everyone in the system. That's cold comfort to an individual beneficiary navigating a denial, but it's exactly why treating every deadline as truly final — and filing well before it, not on it — is the single most important habit in the entire appeals process.
