Coinsurance
Coinsurance is the percentage of costs you pay for covered services after you've met your deductible. For example, if your coinsurance is 20%, you pay 20% and Medicare pays 80%.
Understanding Coinsurance
Coinsurance is the percentage of costs you pay for covered health care services after you've paid your deductible. For example, Original Medicare typically covers 80% of approved charges, leaving you with 20% coinsurance.
Unlike a copay (which is a fixed amount), coinsurance is a percentage of the total cost. This means your share can vary significantly depending on the cost of the service.
With Original Medicare, there's no limit on how much you might pay in coinsurance over a year, which is why many people purchase Medigap (Medicare Supplement) insurance.
In Part D, you typically pay coinsurance (a percentage) for higher-tier drugs and during certain coverage phases, while lower-tier drugs may have flat copays.

Copayment
A copayment (copay) is a fixed amount you pay for a covered service, like $20 for a doctor visit. Different services may have different copayments.
Deductible
A deductible is the amount you pay for covered services before your insurance starts to pay. Medicare has separate deductibles for Part A, Part B, and Part D.
Medigap
Medigap (Medicare Supplement Insurance) is private health insurance that helps pay some of the health care costs that Original Medicare doesn't cover, like copayments, coinsurance, and deductibles.
Maximum Out-of-Pocket (MOOP)
The maximum out-of-pocket is the most you pay in a year for covered services. Once you reach this limit, your plan pays 100% of covered costs for the rest of the year.
