Medicare Drug List Formulary
HealthSpring’s formulary is a comprehensive list of drugs that are covered by your Medicare Advantage (MA) or Part D Prescription Drug (PDP) plan. Our doctors and pharmacists select these drugs for their effectiveness, safety, ease of use and cost.

Covered Drug Lists
Review the drug lists below to see if your medication is covered depending on your plan. If your medication appears on the drug list, then it is a covered medication under that plan. Your medication might have certain requirements if they meet prior authorization criteria or step therapy criteria. You can use the list to check for other medications that treat your condition.

HealthSpring Medicare Part D Drug Lists
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 two 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.
Generics
All 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.

Medicare Drug Formulary Changes
During a plan year, HealthSpring 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 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.
It is important that you check your plan’s drug list PDF on this page or the 2026 Medicare Prescription Pricing and Comparison Tool to confirm the coverage of your medications.
Transitioning to a New Plan
