How long does the full appeal process take?

Level 1 is 7 days. Level 2 is another 7. Level 3 (ALJ) can take 3-12 months. If your health is at immediate risk, request the EXPEDITED track at every level — standard timelines compress to 72 hours. Don’t accept slow walks when you’re actively losing health ground.

Can I get a bridge supply while I appeal?

Yes, in two ways. First, many manufacturers run bridge programs during appeal periods — ask the drug maker directly. Second, some plans have transition-supply rules for new enrollees. Ask your pharmacist to run the claim with an "exception" — it sometimes produces a temporary fill.

What if my doctor won’t write the appeal letter?

Push back politely — medical-necessity letters are part of standard insurance work. If they still refuse, consider switching to a prescriber who specializes in your condition; specialists tend to be better about this documentation. Patient advocacy groups (HealthWell, PAN) sometimes also provide letter templates you can hand to your prescriber.

Are commercial-plan appeals the same?

Similar structure but different timelines and final review bodies — commercial appeals go through state Department of Insurance or, for ERISA-covered employer plans, federal court. Still 3-5 levels typically. Check your plan’s Summary of Benefits for the specific appeal process.

The 5-level appeal: winning a Medicare Part D denial

If you’re on Medicare and your Part D plan denies prior authorization for a drug, you have five levels of appeal. Most patients stop at level 1. Of those who push to level 3 (Administrative Law Judge), around 60% win reversals, according to CMS data — so persistence genuinely pays off.

Here’s the step-by-step playbook.

Level 1: Redetermination (by the plan)

This is a re-review by your Part D plan — the same company that denied you. You have 60 days from the denial notice to request it.

How to ask: call the member-services number on your card, or mail/fax a written request.
Who writes: you, your prescriber, or an authorized representative.
Plan must respond: 7 days (standard) or 72 hours (expedited — use this if waiting risks serious health harm).
Documentation to include: the denial letter, your prescriber’s medical justification, relevant medical records. The stronger the clinical letter, the better.

If denied again, you move to level 2.

Level 2: Independent Review Entity (IRE)

Now an outside contractor reviews — not the plan. Send your request to MAXIMUS Federal Services (the current CMS-contracted IRE) within 60 days of your level-1 denial.

Timeline: 7 days standard, 72 hours expedited.
Strengthen your case: add new clinical evidence if any — lab values, trial-and-failure documentation for step therapy, specialist consult notes.

Level 3: Administrative Law Judge (ALJ)

This is where win rates climb to around 60%. You need at least $190 in amount-in-controversy (2026 threshold — roughly 2 months of the drug’s retail cost). You have 60 days to request an ALJ hearing after level 2.

Format: usually a phone or video hearing. You or your representative can speak, and your prescriber can join to testify.
Timeline: months. The ALJ backlog was a known issue but has improved.
Why win rates jump: ALJs apply medical-necessity standards more case-by-case. A well-documented appeal with specialist backing usually succeeds.

Level 4: Medicare Appeals Council

Rarely needed if you won at level 3. If the plan appeals the ALJ decision, the Medicare Appeals Council reviews.

Level 5: Federal district court

Only if the amount is large (over $1,900 in 2026) and the issue involves a legal question. Uncommon for drug appeals.

The clinical letter is the whole ballgame

Denials are almost always overturned by a strong letter of medical necessity from your prescriber. A good letter states:

Your specific diagnosis (with ICD-10 codes)
Drugs tried previously and why they failed (for step therapy)
Why the requested drug is clinically indicated per guidelines
What happens if you don’t get it (disease progression, hospitalization risk)
Peer-reviewed evidence or clinical guidelines supporting the choice

Ask your prescriber’s office specifically for a Letter of Medical Necessity for Medicare Part D appeal, Level [N]. Most clinic offices have templates.
