What is ORIGINAL MEDICARE PLAN?
ORIGINAL MEDICARE PLAN meaning A pay-per-visit 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. The Original Medicare Plan has two parts: Part A (Hospital Insurance) and Part B (Medical Insurance).
