If you must pay an income-related monthly adjustment amount, your total Medicare Part B premium will be the sum of:
The Medicare Part B standard monthly premium, determined using the rules in 42 CFR 408.20; plus
Any applicable increase in the Medicare Part B standard monthly premium as described in 42 CFR 408.22; plus
Your income-related monthly adjustment amount.
The nonstandard Medicare Part B premium amount described in 42 CFR 408.20 does not apply to individuals who must pay an income-related monthly adjustment amount. Such individuals must pay the full Medicare Part B standard monthly premium plus any applicable penalties for late enrollment or reenrollment plus the income-related adjustment.
