Whether you had a Medicare advantage plan or a stand alone prescription drug plan, it’s important to understand that every September you should receive a statement of benefits which goes over your plans formulary ( list of covered medicines ) as well as co pays and co insurance for your current health plan or PDP.
The point is plans change from year to year. You need to understand this. You don’t want to find this out late in the year when you can’t make a change. This can cost you significant dollars.
