Tufts Medicare Preferred HMO
Group Retiree 2020 Formulary (List of Covered Drugs)

A formulary is an entire list of Part D drugs covered by Tufts Medicare Preferred HMO.


Note to existing members: This formulary has changed since last year. Please use our search tool to make sure that it still contains the drugs you take.  While the formulary may change throughout the year, in general, if you are taking a drug on our formulary that was covered at the beginning of the year, we will not discontinue or reduce coverage of the drug during the year.  If we remove a drug from our formulary, add any restrictions, or move a drug to a higher cost-sharing tier, we must notify affected members of the change at least 60 days before the change becomes effective.

All drugs that require Prior Authorization

All drugs that require Step Therapy Prior Authorization

Tufts Health Plan Medicare Preferred covers both brand name drugs and generic drugs. A generic drug is approved by the FDA as having the same active ingredient as the brand name drug. Generally, generic drugs cost less than brand name drugs.
