In order for a new drug to be listed in the Medicare Plan Finder it must first be added to the CMS Formulary Reference File (FRF). The last FRF was created in July so drugs that have come onto the market since then will not be listed in the Medicare Plan Finder until early 2018. However, prescription drug plans may still be covering your new drug. You can call the plans directly, or check their websites for more up-to-date information.
