Medicare Drug List Formulary

See if your prescriptions are covered by your Medicare plan.

What is a formulary?

formulary, or comprehensive drug list, is a list of commonly prescribed drugs that are covered by your plan. Cigna doctors and pharmacists pick these drugs for their effectiveness, safety, ease of use, and cost. Drug lists can change from year to year.

Lists of Covered Drugs

Below are the lists of covered drugs in our Cigna Medicare Advantage Plans (Part C) and Medicare Prescription Drug Plans (Part D). If your medication appears on the drug list, then it is a covered medication under that plan. Your medication might have certain requirements, such as prior authorization, quantity limits, or step therapy. You can use the list to check for other medications that treat your condition.

Complete Drug List Formulary

Each Medicare Part D Prescription Drug Plan must follow the rules set forth by Medicare for covering Part D drugs and be approved by Medicare each year. Medicare Part D Prescription Drug Plans must include at least 2 drugs in every drug category. In addition, each Medicare Part D Prescription Drug Plan must:

  • Make sure you have convenient access to retail pharmacies
  • Have a process to request exceptions to the drug list
  • Provide useful information to you, such as how drug lists and medication management programs work, information on saving money with generic drugs, and grievance and appeal processes

Not all prescription drugs are included on the drug list. In some cases, the law prohibits Medicare coverage of certain types of drugs. In other cases, we have decided not to include a particular drug on our drug list because we may have an alternative drug that can be taken.


All Cigna Medicare Part D Prescription Drug Plans cover various brand-name drugs and generic drugs. Generic drugs have the same active ingredients as brand name drugs. Generic drugs usually cost less than brand-name drugs and are rated by the Food and Drug Administration (FDA) to be as safe and effective as brand-name drugs.

Formulary Changes

During a plan year, Cigna may make certain changes to our list of covered drugs. Most changes throughout the year will have a positive impact on customers such as adding new drugs to our drug list, removing restrictions, or moving a medication to a lower cost-sharing tier.

Plans are limited in their ability to make changes during the year that will have a negative impact on customers. A negative change would be removing a medication, moving it to a higher cost-sharing tier, or adding a new requirement. If there are negative changes, in most cases we will post a notice on this site before the change becomes effective. If you are taking the medication with the change you will generally be notified on your Explanation of Benefits (EOB) statement. We also may make a change when a new generic becomes available.

From year to year our drug list may change. It is important that you check the drug list included in your Annual Notice of Changes (ANOC), or the 2022 Cigna Medicare Drug and Pharmacy Search Tool to confirm the coverage of your medications for the next year.
