The key to comparing Medicare Part D plans is evaluating the drug formulary. It doesn't matter if you have a Medicare Advantage plan that includes drugs or you are evaluating a separate Part D plan, you must compare the drugs on the formulary.
Medicare.gov has a drug formulary finder which is beneficial.
I believe Medicare.gov is the most efficient way to compare plans. BTW - you should compare your plan every year during the Annual Enrollment Period, as plan's formularies change and your medication may have changed - so always shop every year during the Annual Enrollment Period. Oct 15th - Dec 7th. (Plan will be effective Jan 1 of the following year)
It may turn out - you are on the least out of pocket cost plan for you for the coming year as well - but better to always check.
If you are on a Supplement and a RX plan - you compare the RX plans, if you are on a Medicare Advantage plan you compare the Advantage plans. (Because your RX is included within each Medicare Advantage plan - typically).
Hope that clarifies!
The best way to compare Medicare Part D drug plans is to use the plan finder at Medicare.gov. You start by entering your zip code, then your county (if the zip covers more than one county). Next, make the appropriate selections for how you get your Medicare and if you receive assistance. Enter the name and dosage of each drug, select a pharmacy and review the results.
