Part D Coverage Determination Process

An initial coverage decision about your Part D drugs is called a Coverage Determination.

Use this process to ask us to make a Part D drug Coverage Decision.

Here are examples of coverage decisions you can ask us to make about your Part D drugs:

1. You can ask whether a drug is covered for you and whether you satisfy any applicable coverage rules. (For example, when your drug is on the Plan’s List of Covered Drugs but we require you to get approval from us before we will cover it for you.)

2. You can ask us to pay for a prescription drug you already bought.

3. You can ask us for an exception. (If a drug is not covered in the way you would like it to be covered, you can ask the Plan to make an “exception”.)

Requests for exceptions are a type of coverage determination. Here are examples of exception requests:

  • Asking for coverage of a drug that is not on the drug list
  • Asking to pay a lower cost-sharing amount for a covered non-preferred drug
  • Asking us to remove the extra rules and restrictions on the Plan’s coverage for a drug such as:
    • Being required to use the generic version of a drug instead of the brand name drug
    • Getting plan approval in advance before we will agree to cover a drug for you
    • Quantity Limits
Important Information to Know About Asking for Exceptions
When you ask for an exception, your doctor or other prescriber will need to explain the medical reasons why you need the exception approved. Your doctor or other prescriber must give us a written statement that explains the medical reasons for requesting an exception. For a faster decision, include this medical information from your doctor or other prescriber when you ask for the exception
