Where do you want to start?
Three entry points, depending on what is on your mind today.
What is Medicare?
Medicare is the federal health insurance program for people age 65 or older and for some younger people with qualifying disabilities. It is organized into four parts: Part A (hospital), Part B (medical), Part C (Medicare Advantage), and Part D (prescription drugs).
- Part A covers inpatient hospital stays, skilled nursing, hospice, and some home health. Most people pay no premium.
- Part B covers doctor visits, outpatient care, lab tests, and preventive services. It carries a monthly premium.
- Part C (Medicare Advantage) is an alternative to Original Medicare offered by private insurers. It bundles A, B, and usually D.
- Part D covers prescription drugs through private plans.
When can I enroll in Medicare?
Most people enroll during their Initial Enrollment Period: the seven-month window that starts three months before the month they turn 65 and ends three months after. Missing this window can trigger late enrollment penalties that last for life.
Other windows include the General Enrollment Period (Jan 1 to Mar 31), the Annual Enrollment Period for Part C and D (Oct 15 to Dec 7), and the Medicare Advantage Open Enrollment Period (Jan 1 to Mar 31). State-specific rules can change your options.

Medicare Advantage replaces Original Medicare with a private bundled plan, usually with lower premiums and a defined network. Medigap supplements Original Medicare by covering most of its out-of-pocket costs, with broader provider choice but higher premiums.
The right choice depends on your providers, your prescriptions, your travel patterns, and whether your state offers extra Medigap protections.
Compare side by sideWhat is the Part D late enrollment penalty?
If you go 63 days or more without Medicare Part D or other creditable prescription coverage after becoming eligible, Medicare adds a permanent surcharge to your Part D premium. The penalty is one percent of the national base premium for every month you were uncovered.
