Plain-language definition
A Medicare Part D coverage determination is the drug plan's formal initial decision about a prescription-drug request. It creates the written decision and appeal rights that apply when the result is unfavorable.
What a coverage determination can decide
- Whether the plan will cover or pay for a requested Part D drug.
- Whether to grant a formulary or tiering exception.
- The amount the enrollee must pay for the drug.
- Whether a quantity limit, step-therapy rule, prior authorization, or other utilization requirement has been satisfied or should be waived.
- Whether to reimburse a covered drug already purchased.
Who can request one
The enrollee, the enrollee's prescriber, or an authorized representative may request a standard or expedited determination from the plan. A request for a drug not yet received may generally be made by telephone or in writing. A payment request generally must be written unless the plan accepts it orally.
Different from a redetermination
The coverage determination is the plan's initial formal decision. A redetermination is the level 1 appeal asking the same Part D plan to review an unfavorable coverage determination. The same word “redetermination” is also used in Original Medicare claims, but that is a different process handled by a Medicare Administrative Contractor.
Different from a grievance
A grievance usually concerns service, communication, delay, conduct, or another complaint that is not a coverage or payment decision. When the dispute is whether the plan should cover or pay for a drug, the coverage-determination and appeal process is normally the relevant route.
Practical example
A plan says a prescribed drug is not on its formulary and denies the requested exception after reviewing the prescriber's supporting statement. That denial is an unfavorable coverage determination. The enrollee, representative, or prescriber may then request a level 1 redetermination under the instructions in the notice.
