What is Medicare Part B and what does it cover?
Medicare Part B is the “supplemental medical insurance” portion of Medicare. Part B covers physician services, outpatient radiology and laboratory services, therapy, medically necessary ambulance transport, certain supplies and equipment, and a few other services not covered by Part A. Part B does not cover most outpatient medications. Part B is a voluntary program that requires eligible individuals to enroll and pay a monthly premium. Most people with Part A choose to enroll in Part B as Part A and Part B are designed to provide a comprehensive health plan when used together.
