IRMAA (Income-Related Monthly Adjustment Amount)

Individuals and married couples with an income over a certain limit must pay a higher premium for Part B and an extra amount for Part D coverage in addition to their Part D plan premium. This additional amount is called income-related monthly adjustment amount. Less than 5 percent of people with Medicare are affected, so most people will not pay a higher premium. Visit the Medicare Parts A & B Income Related Adjustment Amounts page for information about income limits.
