Generally, people 65 or older and some under 65 with certain disabilities or conditions are eligible for Medicare.
The Initial Enrollment Period starts three months before you turn 65 and ends three months after the month you turn 65. Signing up during this window helps avoid coverage gaps and late penalties.
Original Medicare includes Part A (hospital) and Part B (medical). Medicare Advantage (Part C) plans are offered by private insurers and often include additional benefits like prescription coverage.
It depends on your plan. Original Medicare lets you see any provider that accepts Medicare, while Medicare Advantage plans may have network restrictions.
You may have to wait for a Special Enrollment Period or the next General Enrollment Period, and you could face late enrollment penalties.
