Enrollment Deadlines and How to Avoid Costly Penalties
Timing your Medicare enrollment correctly protects you from coverage gaps and lifelong financial penalties. Missing your designated sign-up window can prove very costly.
Key Enrollment Periods
Your Initial Enrollment Period (IEP) lasts seven months. It begins three months before your 65th birthday month, covers your birth month, and ends three months after.
The Annual Open Enrollment Period runs every year from October 15 to December 7. Any plan changes you make during this window take effect on January 1.
If you are enrolled in Medicare Advantage, the Medicare Advantage Open Enrollment Period runs from January 1 to March 31. You can switch Advantage plans or return to Original Medicare.
Understanding Late Enrollment Penalties
If you miss your Initial Enrollment Period without creditable employer coverage, you face a 10% Part B penalty for each full 12-month period you delayed.
This Part B penalty is added to your monthly premium for the rest of your life.
Part D also charges a permanent late enrollment penalty if you go without creditable drug coverage for 63 consecutive days or more after becoming eligible.
You can safely delay Part B and Part D if you or your spouse actively work and receive qualifying health insurance from an employer with 20 or more workers.
