Medicare appeals run through five levels: redetermination, reconsideration, an ALJ hearing, the Appeals Council, and federal court. Most practices abandon after redetermination — the level with the lowest overturn rate — leaving the more favorable levels entirely unused.
Medicare provides five levels of appeal. Most practices use one, and it is the least favorable one.
The levels
- Redetermination — reviewed by the same contractor that denied the claim.
- Reconsideration — reviewed by an independent contractor, a different organization.
- Administrative Law Judge hearing — an actual hearing, with a minimum amount in controversy.
- Medicare Appeals Council review.
- Federal district court review, above a higher threshold.
Why stopping at level one is the wrong place
Level one is decided by the organization that made the original decision. Reversal requires them to conclude their own determination was wrong. That is not a hostile process, but it is structurally the least likely place to prevail.
Level two moves to an independent reviewer with no stake in the original decision. It is a genuinely different reading, and it is where a well-documented appeal has the most room to succeed.
What stops practices
Effort, mostly. Each level has its own deadline and format, and without a defined process every appeal is reinvented. The amount-in-controversy threshold at level three also rules out individual small claims — though claims can sometimes be aggregated to meet it, which is the part most practices do not know.
A workable policy
- Appeal to level two by default when the denial is contestable and the balance justifies it.
- Track deadlines per level. They differ, and missing one ends the matter permanently.
- Group similar denials. One argument built once can serve many claims and can help clear the threshold for higher levels.
None of this makes an outcome certain — the decision is the adjudicator's. It just stops the practice from conceding at the point where conceding is least justified.
Aggregate to reach the threshold
Individual claims frequently fall below the amount in controversy required at the ALJ level, and claims can be combined to meet it.
That turns a set of individually uneconomic appeals into one worth pursuing, and it is the mechanism most practices are unaware of.
Calendar every deadline at the moment of decision
Each level starts a new clock from the prior determination. An appeal abandoned by accident because a deadline passed is indistinguishable from one abandoned on the merits.
Record the next deadline the day each decision arrives.
Decide the escalation policy in advance
Deciding case by case whether to go beyond redetermination means almost never going. A standing rule — denials above a threshold in defined categories proceed automatically — is what actually gets claims to the levels where they win.
What each level actually is
Redetermination is reviewed by the same contractor that denied the claim, which is part of why overturn rates there are modest. Reconsideration goes to a Qualified Independent Contractor — a genuinely different reviewer. The ALJ level is a hearing before an Administrative Law Judge, where you can present the case rather than submit a file.
Beyond that, the Medicare Appeals Council reviews the ALJ decision, and federal court is the final route.
Prepare differently at each stage
Redetermination is largely a paper exercise and rewards a tight, specific submission. Reconsideration is the point to add anything the first reviewer did not have. The ALJ hearing is the only level where a person hears the argument, which changes what preparation is worth doing.
Submitting the same package at every level is the most common approach and the least effective one.
Backlogs are real
The ALJ level has historically carried substantial waiting times. That does not make it not worth pursuing, but it does mean the cash is distant and the claim needs tracking for far longer than a normal denial.
Decide up front whether you are prepared to wait, because abandoning at that stage wastes everything spent getting there.
Common questions
- What are the five levels of Medicare appeal?
- Redetermination by the contractor, reconsideration by a Qualified Independent Contractor, an Administrative Law Judge hearing, Medicare Appeals Council review, and judicial review in federal court.
- Which Medicare appeal level has the best odds?
- The ALJ level has historically been considerably more favorable than redetermination, which is exactly the level most practices never reach.
- How long do I have to file a Medicare appeal?
- Each level has its own deadline running from the prior decision. Missing one ends the appeal regardless of the merits.
- Is there a minimum amount to reach an ALJ hearing?
- Yes, there is an amount in controversy threshold at the ALJ level, and claims can be aggregated to meet it.
- Why do practices stop after redetermination?
- Because it is the level they know, and a denial there feels final. The subsequent levels are less familiar, slower, and where the outcomes improve.
