HMSA Medicare Advantage Coverage Determination Request


A coverage determination or coverage decision is HMSA’s initial decision about whether we’ll provide coverage for a Part D prescription drug, allow an exception request, or lower a drug tier.

You, your prescriber, or your authorized representative can ask us to make a coverage determination verbally or in writing. If your health requires a quick response, you must ask us to make a “fast coverage decision.” A “fast coverage decision” is also called an “expedited coverage determination.” When we give you our decision, we’ll use the “standard” deadlines unless we’ve agreed to use the “fast” deadlines. A standard coverage decision means we’ll give you an answer within 72 hours after we receive your doctor’s statement. A fast decision means we’ll answer within 24 hours.


To request a coverage determination, contact CVS Caremark. CVS Caremark is HMSA’s pharmacy benefit manager. For information about the process or the status of a request, contact CVS Caremark.
