Understanding Medicare Formulary Exceptions — And How to Get One
When you’re enrolled in a Medicare Part D or Medicare Advantage plan with prescription drug coverage, your plan covers medications according to the plan’s formulary; the list of drugs the plan agrees to cover. What happens if the prescribed medication isn’t on that list, or it’s coverage has restrictions? That’s when understanding Medicare formulary exceptions becomes very important.
A formulary exception is a special request made by a plan enrollee with supporting information from their doctor or directly from their doctor for a plan to cover a drug that’s not included in the plan’s formulary, or to waive certain restrictions, like prior authorization or step therapy.
When You Might Need a Formulary Exception
You might need to request an exception if:
- Your medication isn’t on your plan’s formulary.
- Your plan requires step therapy, meaning you must first try a different (and usually less expensive) drug before the one your doctor prescribed.
- There’s a quantity limit, and your doctor believes you need more than what’s allowed.
- Your plan makes a formulary change mid-year, and the drug you rely on is no longer covered.
If your doctor determines that no covered drug will work as well for your condition, or that other alternatives could cause adverse effects, you can request an exception.

How to Request a Formulary Exception
Here’s the process step-by-step:
- Talk to your doctor first. Your prescribing doctor must support your exception request and provide medical justification explaining why the specific drug is necessary.
- Submit the request form. You (or your doctor) will complete your plan’s Coverage Determination Form. Most plans provide this form online or through their customer service department.
- Wait for the plan’s decision.
- The plan must make a decision within 72 hours for standard requests.
- If your doctor believes you need the medication sooner due to your health, you can ask for an expedited (fast-track) review, which requires a decision within 24 hours.
- If denied, you can appeal. You have the right to appeal the decision through multiple levels if necessary. Your doctor can help provide additional medical documentation to strengthen your case.
Tips for a Successful Exception Request
- Provide clear medical justification. The more detailed your doctor’s explanation, the better.
- Submit supporting evidence. Include prior medical history, records of failed alternative treatments, or side effect reports.
- Act early. If you know your plan doesn’t cover a medication, start the exception process before you run out of your current supply.
Formulary exceptions can seem complicated, but they exist to ensure you have access to the medications you truly need. Working closely with your doctor and following your plan’s process carefully can make all the difference.
