Premiums for Medicare Part B (which covers some doctor’s bills, home health care, and medical equipment) are pricey at $164.90 a month, about $1,979 a year. But 7% of people with Part B get hit with a special Medicare monthly surcharge that can boost those premiums dramatically.
That surcharge is known as an Income-Related Monthly Adjustment Amount, aka IRMAA. In 2023, it can more than triple Part B premiums to as much as $560.50 a month or $6,732 for the year.
