You’ll see a lot of different terms as you learn more about the Medicare plans. Some can be confusing, so here are a few that you should understand:
Co-payment: A set amount that you will need to pay for each provider visit and other services.
Coinsurance: After you meet your deductible, coinsurance is the cost you pay for a service. This amount will come as a bill from your doctor after Medicare has paid its portion.
Cost-sharing: This is the part of costs you will owe for your care. Cost-sharing is the same as out-of-pocket costs.
Deductible: The total amount you pay each year before your insurance kicks in. This amount can change each year, even if you pick the same plan you had before.
In-network: A provider, hospital or pharmacy that is covered by the plan you picked. In-network care will usually cost less than out-of-network care. Before you pick a Medicare plan, talk to your primary care provider and specialists to find out what plans they accept.
Open enrollment period: Between Oct. 15 and Dec. 7 each year, patients aged 65 and older pick the Medicare plan that will cover their health care costs for the next year.
Out-of-network: A provider, hospital or pharmacy that is not covered by the plan you picked.
Out-of-pocket costs: The amount you pay for your care because it is not covered by Medicare. This total can include co-payments and cost-sharing. (Maximum Out-of-Pocket, or MOOP, is the most that you will pay each year in “out-of-pocket” costs.)
Premium: The amount you pay each month to Medicare or another insurance company for your healthcare coverage.
Prior authorization: Insurance plans often require providers to get their approval before delivering certain services. If you get the service without prior authorization, the payer may not cover the service.
Specialist: Your primary care physician takes care of your whole body, while a specialist cares for one part. For example, you may have allergy testing done by an allergist or see a geriatrician as you age.
Supplemental insurance: Some patients choose to buy an extra plan to cover services that aren’t paid for by Medicare. These extra plans, sometimes called Medigap, supplement Medicare coverage.
