In what has become an annual ritual, the Centers for Medicare & Medicaid Services (CMS) have announced the 2025 premiums, deductibles, and coinsurance amounts for the Medicare Part A and Part B programs, and the 2025 Medicare Part D income-related monthly adjustment amounts.
Rates are based on annual income from two years prior, which means that you income in 2023 will determine the rates you pay for 2025.
