How this calculator works:

This tool uses your date of birth to estimate the 7-month Initial Enrollment Period (IEP) when most people can first sign up for Medicare.

For most people who enroll in Part B at 65:

- This 7-month window is also their Initial Coverage Election Period (ICEP) for Medicare Advantage plans.

- In many cases, it is also when they can first sign up for a Medicare Part D prescription drug plan.

If you delay signing up for Part B past age 65, or if you qualify for Medicare earlier due to disability, your actual enrollment windows may be different.

Medicare Enrollment Window Calculator

Enter your date of birth to see your 7-month Initial Enrollment Period (IEP). For most people, this same window is also the Initial Coverage Election Period (ICEP) for Medicare Advantage.

This calculator uses only your date of birth to estimate your 7-month Initial Enrollment Period (IEP) and, for most people, your Initial Coverage Election Period (ICEP) for Medicare Advantage. Results are estimates only. Enrollment rules can be different if you delay Part B, qualify for disability, or have other special circumstances. Please confirm your dates with Medicare (Medicare.gov) or Social Security (SSA.gov).
