8.3 Coverage Determinations, Exceptions & Appeals
Key Takeaways
- A coverage determination is the plan's initial decision on a drug claim; standard decisions are due within 72 hours, expedited decisions within 24 hours.
- Formulary and tiering exception requests require the prescribing physician's supporting statement before the plan can decide.
- The five Part D appeal levels are: redetermination (plan), reconsideration (Independent Review Entity), ALJ hearing (OMHA), Medicare Appeals Council review, and federal judicial review.
- 2026 amount-in-controversy thresholds are $200 to reach an ALJ hearing (Level 3) and $1,960 to reach federal court (Level 5) — no dollar threshold applies at Levels 2 or 4.
- Only the beneficiary, the prescribing physician, or a formally appointed representative (CMS Form 1696) may file a coverage determination, exception, or appeal — agents refer clients to plan member services rather than filing on their behalf.
Why Coverage Determinations and Appeals Matter on the Exam
Module 3 tests more than plan mechanics — it tests whether an agent understands a beneficiary's due-process rights when a drug claim is denied, and just as importantly, where the agent's role ends. AHIP exam questions on this topic typically present a denial scenario and ask which appeal level or timeframe applies, or ask who is legally allowed to file the request. Getting the sequence of the five appeal levels backward, or confusing standard with expedited timeframes, is the single most common wrong answer pattern here.
The Starting Point: Coverage Determinations and Exceptions
A coverage determination is the first decision a Part D plan makes about a beneficiary's drug benefits — whether a specific drug is covered, whether a prior authorization requirement is met, what tier a drug is billed at, or whether an exception should be granted. Every appeal in the process traces back to an initial coverage determination.
Two special types of coverage determination requests are exceptions:
- Formulary exception — a request that the plan cover a drug that is not on its formulary at all.
- Tiering exception — a request that a formulary drug be covered at a lower-cost tier than the plan normally assigns it.
Exception requests require the prescribing physician to submit a supporting statement explaining why the formulary alternatives would not be as effective or would cause adverse effects. Once the plan receives that statement, it must decide within the same timeframes as any other coverage determination.
Standard vs. Expedited Timeframes
| Request Type | Standard Decision | Expedited Decision |
|---|---|---|
| Coverage determination | 72 hours | 24 hours |
| Exception request (after receiving physician's supporting statement) | 72 hours | 24 hours |
| Redetermination (Level 1) | 7 calendar days | 72 hours |
| Reconsideration by IRE (Level 2) | 7 calendar days (14 days for payment-only requests) | 72 hours |
Expedited review applies whenever waiting for the standard timeframe could seriously jeopardize the beneficiary's life, health, or ability to regain maximum function — the same "health, life, or function at risk" standard used across all Medicare appeal levels.
The Five Levels of Appeal
| Level | Name | Decision-Maker | Filing Deadline | AIC Threshold (2026) |
|---|---|---|---|---|
| 1 | Redetermination | The Part D plan sponsor itself | 65 days from the denial notice | None |
| 2 | Reconsideration | Independent Review Entity (IRE), a CMS contractor | 65 days from the Level 1 decision | None |
| 3 | ALJ Hearing | Administrative Law Judge, Office of Medicare Hearings and Appeals (OMHA) | 60 days from the Level 2 decision | $200 |
| 4 | Medicare Appeals Council review | Departmental Appeals Board | 60 days from the ALJ decision | None |
| 5 | Judicial review | U.S. federal district court | 60 days from the Council decision | $1,960 |
Note the pattern the exam likes to test: the plan itself only gets one bite at the apple (Level 1). From Level 2 onward, every decision-maker is independent of the plan — first a CMS contractor (the IRE), then the federal court system. Also note that an amount-in-controversy (AIC) dollar threshold is required to advance to Level 3 and Level 5, but not to reach Level 2 or Level 4 — a detail exam writers frequently flip.
Who Can File
A coverage determination, exception, or appeal may be requested by:
- The beneficiary directly
- The beneficiary's prescribing physician (for coverage determinations and exceptions specifically)
- An appointed representative — someone the beneficiary formally designates using CMS Form 1696 (Appointment of Representative), which is required before anyone other than the beneficiary or prescriber (a family member, for instance) can file or receive information on the beneficiary's behalf
Agents are not automatically authorized to file appeals for clients. If a client asks an agent for help, the agent's correct, compliant role is to explain the process and direct the client to the plan's member services number or website — not to submit the appeal as though acting as a representative without the proper CMS-1696 authorization on file.
Worked Scenario
Mr. Chen's pharmacy tells him his cholesterol medication needs prior authorization, and his Part D plan denies the initial coverage determination. His doctor believes waiting the standard 72 hours could put Mr. Chen's health at serious risk, so the doctor requests an expedited decision — Mr. Chen gets an answer within 24 hours. If the plan still denies it, Mr. Chen (or his doctor) has 65 days to request a redetermination (Level 1) directly with the plan. If the plan upholds its own denial again, the next stop is the independent IRE (Level 2) — not back to the plan, and not straight to a judge.
Key Exam Traps
- Level 1 (redetermination) is decided by the plan itself; only Level 2 and beyond involve an entity independent of the plan.
- An AIC dollar threshold gates Level 3 (ALJ) and Level 5 (federal court) — it does not gate Level 2 (IRE) or Level 4 (Appeals Council).
- Exception requests cannot proceed without the prescriber's supporting statement — a beneficiary cannot request a formulary or tiering exception on their own without physician documentation.
