Copay vs. coinsurance at a glance
A copay (copayment) is a fixed dollar amount you pay for a covered service, such as $30 for an office visit. Coinsurance is a percentage of the plan’s allowed cost for a covered service, such as 20%. Both are forms of health insurance cost sharing, and a plan may use different combinations for visits, prescriptions, tests, and hospital care.
The amount due depends on the exact benefit, whether you have met the applicable deductible, whether the provider is in network, and the plan’s terms. Check the Summary of Benefits and Coverage (SBC) rather than assuming every service follows the same rule.
How a health insurance copay works
When a copay applies, you owe the stated amount for that covered service. For example, if your plan lists a $30 primary-care copay and the visit is covered under that benefit, your share may be $30. Some plans apply the deductible before a copay becomes available for certain services; others cover specific services with a copay before the deductible.
Copays can vary within one plan. A primary-care visit, specialist visit, urgent-care visit, emergency-room visit, and prescription can each have a different amount. Preventive services covered under Marketplace plans may have no cost sharing when you meet the applicable coverage rules.
How coinsurance works after the deductible
Coinsurance is a percentage of the plan’s allowed amount for a covered service. Suppose an in-network service has a $200 allowed amount, your deductible is already met, and your coinsurance is 20%. Your estimated share is $40, while the plan pays the remaining covered amount, subject to its rules.
If you have not met the deductible and the service is subject to it, you may owe more than the coinsurance example—potentially the allowed amount up to the remaining deductible. Out-of-network care can use different rates and may expose you to additional costs. Ask the provider and insurer for an estimate before scheduled care.
Where the deductible and out-of-pocket maximum fit
A deductible is the amount you pay for certain covered services before your plan begins sharing those costs. Some services are exempt from the deductible or have a separate deductible, so check the benefit details. After the deductible, your plan may charge a copay, coinsurance, or both, depending on the service.
The annual out-of-pocket maximum limits what you pay for eligible in-network covered benefits under the plan. Premiums, noncovered care, most out-of-network balance bills, and other excluded amounts generally do not count toward that limit. The exact plan documents control.
How to compare copays and coinsurance before enrolling
Look at more than the monthly premium. Compare the deductible, primary-care and specialist copays, urgent and emergency care costs, hospital coinsurance, prescription tiers, provider network, and out-of-pocket maximum. Then consider the care you expect to use and whether your preferred doctors, hospitals, and medications are covered.
A licensed agent can help translate the plan summary and compare available health insurance options. Review the official HealthCare.gov guide to total health care costs and compare plans using the details that matter to you.
Frequently asked questions
Is a copay or coinsurance better?
Neither is automatically better. A fixed copay can make a particular service easier to estimate, while a coinsurance percentage depends on the allowed cost. Compare the full plan design, expected care, network, deductible, and out-of-pocket maximum.
Do I pay coinsurance before meeting my deductible?
For services subject to the deductible, you generally pay the allowed costs until meeting it, then the plan’s coinsurance may apply. Some services are covered before the deductible or have separate rules, so check the plan documents.
Can a health plan have both copays and coinsurance?
Yes. A plan can use copays for some services and coinsurance for others, and the deductible may apply to either depending on the benefit.
Do copays count toward my out-of-pocket maximum?
Eligible copays for covered in-network benefits generally count toward the plan’s out-of-pocket limit. Premiums, noncovered services, and many out-of-network charges do not. Confirm the plan’s SBC and policy documents.
