Part B (medical insurance)
Medicare Part B helps cover doctor's services, outpatient care, and some other services not covered by Part A. Part B is optional and has a monthly premium. This premium is deducted from your monthly Social Security check or billed quarterly if you're not yet receiving Social Security.
When to enroll
- When you first become eligible, by age, disability, or other criteria. This Initial Coverage Election Period (ICEP) lasts 7 months.
- During the annual General Enrollment Period for Medicare Parts A and B: January 1 through March 31 each year. Coverage starts July 1.
If you don't enroll in Part B when you're first eligible for Medicare, and you decide to enroll later, your monthly Part B premium could go up 10 percent for each year that you could have had Part B but didn't enroll.
If you have other coverage, such as employer-sponsored coverage, when you first become eligible for Medicare, you can defer your Medicare Part B enrollment to a later time without penalty — up to 8 months after your other coverage ends. Contact Social Security to find out more about deferring your Part B enrollment.
Some services not covered by Part B
- Routine vision, alternative health care, routine hearing screening exams, routine chiropractic care, prescription drugs, first 3 pints of blood
- Chiropractic services (except to correct a subluxation using manipulation of the spine)
- Cosmetic surgery
- Custodial care
