Coinsurance

A type of savings account that lets you set aside money on a pre-tax basis to pay for qualified medical expenses. By using untaxed dollars in a Health Savings Account (HSA) to pay for deductibles, copayments, coinsurance, and some other expenses, you may be able to lower your overall health care costs. HSA funds generally may not be used to pay premiums.

Health plans that meet all of the requirements applicable to other Qualified Health Plans (QHPs) but that don't cover any benefits other than 3 primary care visits per year before the plan's deductible is met. The premium amount you pay each month for health care is generally lower than for other QHPs, but the out-of-pocket costs for deductibles, copayments, and coinsurance are generally higher. To qualify for a Catastrophic plan, you must be under 30 years old OR get a "hardship exemption" because the Marketplace determined that you’re unable to afford health coverage.

The share of costs covered by your insurance that you pay out of your own pocket. This term generally includes deductibles, coinsurance, and copayments, or similar charges, but it doesn't include premiums, balance billing amounts for non-network providers, or the cost of non-covered services. Cost sharing in Medicaid and CHIP also includes premiums.

A discount that lowers the amount you have to pay for deductibles, copayments, and coinsurance. In the Health Insurance Marketplace®, cost-sharing reductions are often called “extra savings.” If you qualify, you must enroll in a plan in the Silver category to get the extra savings.

Original Medicare is a fee-for-service health plan that has two parts: Part A (Hospital Insurance) and Part B (Medical Insurance). After you pay a deductible, Medicare pays its share of the Medicare-approved amount, and you pay your share (coinsurance and deductibles).
