Part B covers 2 types of services:
- Medically necessary services: Services or supplies that are needed to diagnose or treat your medical condition and that meet accepted standards of medical practice.
- Preventive services: Health care to prevent illness (like the flu) or detect it at an early stage, when treatment is most likely to work best.
When should you enroll?
If you're automatically enrolled, you'll get your red, white, and blue Medicare card in the mail 3 months before your 65th birthday or your 25th month of disability.
In most cases, if you don’t sign up for Medicare Part B when you’re first eligible, you’ll have to pay a late enrollment penalty. You'll have to pay this penalty for as long as you have Part B and could have a gap in your health coverage.
