How Much Does Medicare Pay For Cymbalta When The Cost Is $260? 
Cymbalta will have different costs with each Part D RX plan or the Rx plans built inherently into Medicare Advantage Plans -LRB- Part C plans -RRB- . Each plan has a formulary which tiers the drugs and then ties each tier to a copay . You will not find Cymbalta in a lower copay tier with most carriers as they will all have it listed as a tier 3 or tier 4 medication . There are some plans that have lower copays associated with tier 3 however . Most companies charge a $ 45 to $ 50 copay for a one month supply of a tier 3 drug . There are some plans that have a $ 18 to $ 25 copay for tier three which could save you some money . The last thing to keep in mind is regardless of the copay amount , a drug like Cymbalta is going to push you into the Part D coverage gap `` donut hole '' much faster than a lower cost generic would do .
