In 2023, the base cost of Part B is $164.90 – but it can be more based on your income. The acronym for this cost adjustment is IRMAA (Income Related Monthly Adjustment Amount).
NOTE #1 – If you have a Medicare Supplement with a separate prescription drug plan, there is also an increase in the cost of Part D (Prescription Drug Coverage). This increase will be added to the cost of your drug plan. However…
If you have a Medicare Advantage Plan, the drug coverage is included in the plan. So even if your plan cost $0, you will still have to pay the Part D IRMAA charge if you’re in a higher income bracket.
NOTE #2 – Your income from 2 years ago is generally the figure used to determine IRMAA. If you were earning more income 2 years ago than you are now, and you want to appeal the IRMAA amount, click here for the appeal form.
