Your Medicare Coverage

Is my test, item, or service covered?

Medicare Part B (Medical Insurance) covers medically necessary diagnostic and treatment services you get as an outpatient from a Medicare-participating hospital. Covered outpatient hospital services may include:

Emergency or observation services, which may include an overnight stay in the hospital
Services in an outpatient clinic, including same-day surgery
Laboratory tests billed by the hospital
Mental health care in a partial hospitalization program, if a doctor certifies that inpatient treatment would be required without it
X-rays and other radiology services billed by the hospital
Medical supplies, like splints and casts
Preventive and screening services
Certain drugs and biologicals that you wouldn’t usually give yourself

All people with Medicare are covered.

You generally pay 20% of the Medicare-approved amount for the doctor or other health care provider's services, and the Part B deductible applies.
For all other services, you also generally pay a copayment for each service you get in an outpatient hospital setting. You may pay more for services you get in a hospital outpatient setting than you would pay for the same care in a doctor's office.
For some screenings and preventive services, coinsurance, copayments, and the Part B deductible don't apply (so you pay nothing).
