) Member ID number, (2
) Rx BIN, (3
) PCN, and (4
) Group ID (or Rx Group) number are the four numbers that uniquely identify you and your Medicare Part D prescription drug plan - and these four numbers are usually found on your Medicare Part D Member ID card and most of you Medicare plan correspondence or printed information (such as your plan's Welcome letter and Evidence of Coverage document).
These four numbers are also needed to fill your prescriptions using your Medicare Part D prescription drug plan.
What does a BIN, PCN, and Rx Group number look like?
Here is an example, of these three numbers for an older WellCare Medicare Part D prescription drug plan:
GROUP (or RxGroup): 788257
particular example, these three numbers are the same for all WellCare
Medicare Part D prescription drug plans (in this case, the WellCare Classic and WellCare
Signature Part D plans) in all states across the country.
However, the BIN, PCN, and RxGroup number can vary between Medicare plans and may change year-to-year.
