The answer
What does Medicare Part B cover?
Medicare Part B covers doctor visits, outpatient care, and many preventive services.
That includes care from physicians and specialists, lab tests, X-rays, mental health services, durable medical equipment such as walkers and wheelchairs, and preventive screenings and vaccines. Part B is the medical, outpatient side of Original Medicare, while Part A handles inpatient hospital care. Part B also covers some limited drugs given in a clinical setting, such as certain injections, though it does not cover most pharmacy prescriptions; those fall under Part D. In 2026, Part B has a standard monthly premium of $202.90 and a yearly deductible of $283, the amount you pay before Medicare shares costs. After the deductible, you typically pay coinsurance for covered services.
