Some of the most common Medicare mistakes include:

- Missing enrollment deadlines

- Not signing up for Part D drug coverage when first eligible

- Choosing a plan without checking doctor networks

- Not reviewing prescription drug formularies

Avoiding these mistakes can help prevent penalties, coverage gaps, and unexpected healthcare costs.

Missing your Initial Enrollment Period can result in:

- Delayed coverage

- Late enrollment penalties

- Limited enrollment windows

Late enrollment penalties can apply if you delay certain parts of Medicare without qualifying coverage.

Examples include:

- Part B penalty: Higher monthly premium for as long as you have Medicare

- Part D penalty: Permanent increase in prescription drug premiums

These penalties are designed to encourage people to enroll when first eligible.
