Part D Appeal for Denied Drug: The 5-Level Medicare Appeals Process
When the Pharmacy Says No
Your parent's plan denied coverage for a prescribed medication. Maybe the drug requires prior authorization the doctor hasn't submitted yet. Maybe the plan says a cheaper alternative must be tried first. Maybe the drug isn't on the formulary at all. Whatever the reason, the denial triggers a structured federal appeals process.
Here are the five levels, from fastest to most formal.
Level 1: Coverage Determination Request
Who decides: The plan sponsor (your parent's insurance company) Deadline to file: Submit promptly; if denied, the redetermination request is due within 65 calendar days of the initial denial notice Decision timeline: 72 hours standard, 24 hours expedited
This is your first formal request. Submit Form CMS-10146 or a detailed written request to the plan's pharmacy coverage department. The prescribing doctor must submit a clinical statement explaining why the denied drug is medically necessary and why covered alternatives won't work.
For expedited review, the doctor must certify that waiting 72 hours would seriously jeopardize the patient's life, health, or ability to regain function. If the patient needs the medication immediately — common after hospital discharge — always request expedited.
Level 2: Redetermination
Who decides: The same plan sponsor, different reviewer Deadline to file: Within 65 calendar days of the initial denial notice Decision timeline: 7 days standard, 72 hours expedited
If Level 1 is denied, file a written redetermination request. Submit additional clinical documentation — a specialist's letter, lab results, records of adverse reactions to alternatives. The plan assigns a different reviewer who must consider any new evidence.

Level 3: Independent Review Entity (IRE) Reconsideration
Who decides: C2C Innovative Solutions (the federally contracted independent reviewer) Deadline to file: Within 60 days of the Level 2 denial Decision timeline: 7 days standard, 72 hours expedited
This is where the appeal leaves the insurance company entirely. The IRE is independent of the plan.
If the plan upholds its Level 2 denial, request reconsideration by the IRE within 60 days using the submission instructions in the denial notice, and keep the IRE case number.
Level 4: Administrative Law Judge (ALJ) Hearing
Who decides: An Administrative Law Judge within the Office of Medicare Hearings and Appeals (OMHA) Deadline to file: Within 60 days of the IRE denial Minimum amount in controversy: $200 for 2026 Decision timeline: 90 days standard, 10 days expedited
File Form OMHA-100 to request a hearing. The $200 threshold means the disputed coverage must be worth at least that amount — most denied medications exceed this easily. The hearing can be conducted by phone or video; in-person hearings are also available.
This is a quasi-judicial proceeding. The ALJ reviews the full administrative record and can consider new evidence. If you have strong clinical documentation that wasn't available at earlier levels — a new specialist opinion, updated clinical guidelines supporting the drug — present it here.
Level 5: Medicare Appeals Council
Who decides: The Medicare Appeals Council within the Departmental Appeals Board (HHS) Deadline to file: Within 60 days of the ALJ decision
This is the final administrative appeal. The Council reviews the ALJ's decision for legal errors. Few cases reach this level, and the Council can decline to hear the case if it finds no error in the ALJ's analysis. Beyond this, the only recourse is federal district court — which requires the claim to meet a separate monetary threshold.
Practical Tips for Caregivers
Don't stop at Level 1. A Level 1 denial is not final; use the next appeal deadlines if the coverage should be reconsidered.
Document everything with dates. Keep copies of every submission, every denial letter, every physician statement. Note the date and time of every phone call, including the representative's name.
Use the Appointment of Representative form. If you're handling appeals on your parent's behalf, submit Form CMS-1696 to each entity — the plan, the IRE, OMHA. Without it, they may refuse to discuss the case with you.
Request expedited review when clinically warranted. Don't default to standard timelines if the medication gap creates medical risk. The doctor's certification is the trigger.
