Part D – PDP (Prescription Drug Plans)  
Base Premium $33.06 per month.  This base premium is used only for determining certain means based monthly premium adjustments and for computing late enrollment surcharges.  Each drug prescription insurance company establishes their own monthly premium which includes establishing formularies (their list of drugs covered). The rate scales up to $70.70 plus your plan premium per month when income tops $165,000 (single filing status), and scales up to $77.10 plus your plan premium when your income exceeds $750,000 (joint filing status). 
Late enrollment penalties  
Part A 10% surcharge paid for a period equal to twice the number of years  you were entitled to Part A but chose not to enroll.
Part B 10% surcharge for as long as you have Medicare. The penalty increases by 10% for each full 12-month period you were entitled to Part B but chose not to enroll.
Part D The late enrollment penalty is calculated by multiplying 1% of the National base premium (see above) times the number of full, uncovered  months that you were eligible but didn’t join a Medicare drug plan.
