Terms of use

General information only. This site explains Medicare premium rules in plain language. It is not tax, legal, medical, or financial advice, and using it creates no advisor–client relationship. For decisions about your own premiums, rely on the notice Social Security sends you and on Medicare.gov.

Projections. Until CMS publishes the official figures for a year, the numbers shown are projections and statutory calculations, labeled as such on every page. The official CMS figures control if there is ever a difference.

No affiliation. This site is independent and is not affiliated with, endorsed by, or connected to CMS, the U.S. Department of Health & Human Services, Medicare.gov, or the Social Security Administration. "Medicare", "Part B" and "Part D" are used descriptively.

Accuracy. We work from primary sources and correct confirmed errors promptly (see Contact), but we do not warrant that any figure is free of error, and you use the site at your own discretion.
