    • Frequently Asked Questions

    You can enroll in Medicare during your Initial Enrollment Period (IEP), which starts 3 months before your 65th birthday, includes your birthday month, and ends 3 months after. There are also Special Enrollment Periods if you qualify.
    Part A covers hospital stays, Part B covers doctor visits and outpatient care, Part C (Medicare Advantage) is an alternative to Original Medicare, and Part D covers prescription drugs.
    IRMAA stands for Income-Related Monthly Adjustment Amount. It's an additional premium charged to higher-income Medicare beneficiaries for Part B and Part D coverage.
    If you're still working and have employer coverage, you may be able to delay Medicare enrollment without penalty. However, you should coordinate with your employer's benefits department to determine the best timing.
