IRMAA 2023 presents a complex landscape for higher income earners navigating Medicare costs. The Income-Related Monthly Adjustment Amount is no small matter, especially with changes in Part B and Part D coverage premiums.
The interplay between your Modified Adjusted Gross Income (MAGI), Social Security benefits, and IRMAA can seem like an intricate puzzle. Understanding how IRMAA is calculated is the first step to managing costs.
| Individual MAGI | Couple MAGI | Part B Premium | Part D Premium |
|---|---|---|---|
| < $97,000 | < $194,000 | $164.90 | Premium (varies) |
| $97,000 - $123,000 | $194,000 - $246,000 | $230.80 | + $12.20 |
| $123,000 - $153,000 | $246,000 - $306,000 | $329.70 | + $31.50 |
| $153,000 - $183,000 | $306,000 - $366,000 | $428.60 | + $50.70 |
| $183,000 - $500,000 | $366,000 - $750,000 | $527.50 | + $70.00 |
