Glossary

A fee-for-service health plan that lets you go to any doctor, hospital, or other health care supplier who accepts Medicare and is accepting new Medicare patients. You must pay the deductible. Medicare pays its share of the Medicare-approved amount, and you pay your share (coinsurance). In some cases you may be charged more than the Medicare-approved amount. Original Medicare has two parts: Part A (Hospital Insurance) and Part B (Medical Insurance).

Medical or surgical care furnished by a hospital to you if you have not been admitted as an inpatient but are registered on hospital records as an outpatient. If a doctor orders that you must be placed under observation, it may be considered outpatient care, even if you stay under observation overnight.
