What is Medicare?

Medicare is the federal health insurance program for people aged 65 and over, and for some younger people with disabilities. It is not one single plan. It comes in parts, and understanding those parts is the key to choosing well.

Part A
Hospital insurance. Covers stays in hospital, care in a skilled nursing facility, and some home health care.
Part B
Medical insurance. Covers doctor visits, outpatient care, preventive services and medical equipment.
Part C
Medicare Advantage. Private all-in-one plans that bundle Parts A and B, and usually drug coverage too.
Part D
Prescription drug coverage, offered through private plans approved by Medicare.

Who qualifies, and when?

Most people qualify at 65. Your first chance to enroll starts three months before the month you turn 65 and runs for seven months in total. Missing that window can mean paying more for the rest of your life, which is why the timing matters as much as the choice itself.

Good to know: if you are still working at 65 and covered through your employer, different rules may apply. This is one of the most common situations we help people with.

The choice most people face

Once enrolled in Parts A and B, most people either add a Supplement and a drug plan, or switch to a Medicare Advantage plan. Neither path is better for everyone. The right answer depends on your health, your budget, your doctors and where you live, and that is exactly the conversation a licensed agent is for.

Still have questions? That is normal.
