The beneficiary is entitled to Medicare Part B and paid the standard Part B premium.
In 02/11, the beneficiary enrolled in a Medicare Part D plan and paid the plan’s monthly
premium amount. In COM 12/11, SSA determines that the beneficiary should have been
paying IRMAA level three. Equitable relief applies to the Part B premium since the
Part B arrearage of $2,214.00 ($184.50 for each month of 01/11-12/11) is greater than
five times the current standard premium including the current IRMAA-B (5 x ($115.40
+$184.50) = $1,499.50). Since there is also an IRMAA-D arrearage of $551.10 ($50.10
for each month of 02/11-12/11), the IRMAA-D arrearage is added to the Part B arrearage
as amounts due to be collected from the title II payment.
