A prescription that costs $10 or $20 today may not cost the same amount when your Medicare drug coverage resets in January. Medicare Part D plans organize covered medications into tiers, and generally, drugs placed on higher tiers cost patients more. That makes a Medicare drug tier change easy to overlook but potentially expensive, particularly for retirees who take several medications every month. The good news is that a tier change doesn’t automatically mean you’re stuck paying whatever the new price turns out to be. Before Medicare Open Enrollment begins October 15, pull out your medication list and run these numbers.
