Copay vs. coinsurance,
side by side.

A copay is a set dollar amount you pay for a visit or a prescription. Coinsurance is a percentage of the bill. Both are your share of the cost when you get care, and one plan can use a copay for an office visit and coinsurance for a hospital stay. Here's how to read each one before you choose a plan.

Two kinds of cost sharing

A flat fee or
a percentage.

HealthCare.gov defines both terms in its glossary. These examples use its numbers:

A copay is a fixed amount.

Say the allowed amount for a doctor visit is $100 and your plan sets a $20 copay. You pay $20 for that visit. Copays can differ by service, so a specialist, an urgent care visit, and a prescription may each carry their own amount.

Coinsurance is a percentage.

With 20% coinsurance on the same $100 allowed amount, you pay $20 once you've met your deductible, and the plan pays $80. Before you meet the deductible, the whole $100 is yours. On a bigger bill the math grows with it: 20% of $10,000 is $2,000.

Both count toward a ceiling.

What you pay in copays and coinsurance for in-network care adds up toward your plan's out-of-pocket maximum. After you hit that limit, the plan pays all covered in-network costs until the plan year ends. Premiums never count toward it.

Where each one shows up

One plan often mixes the two.

These points summarize HealthCare.gov, copayment, HealthCare.gov, coinsurance, HealthCare.gov, allowed amount, and HealthCare.gov, balance billing, read October 30, 2026. Each plan's summary of benefits lists its own amounts.

Plans can use copays for routine items like office visits and generic drugs, so you know the price before you walk in.
Larger services, such as a hospital stay, surgery, or an MRI, can be priced as coinsurance instead, so your share follows the size of the bill. The plan summary shows which applies.
Coinsurance is a percentage of the allowed amount, the price your plan has agreed to, not the provider's full charge. An out-of-network provider may bill you for the difference, which is called balance billing.
Generally, plans with lower premiums charge higher copays and coinsurance, and plans with higher premiums charge less when you get care.

Metal levels and your share

How metal levels split
the cost of care.

60% to 90%

The estimated share of covered costs a plan pays, from Bronze (60%) up to Platinum (90%). Your share runs from 40% down to 10%.

73% to 94%

The estimated plan share for a Silver plan with extra savings (cost-sharing reductions), depending on how much savings you qualify for.

$12,000

The most a 2027 Marketplace plan can make one person pay in a year for covered in-network care. For a family, the limit is $24,000.

Shares from HealthCare.gov, plan categories and the limit from HealthCare.gov, out-of-pocket maximum/limit, both read October 30, 2026. HealthCare.gov calls the shares estimates; the actual costs you pay vary by plan.

Working with Paul

We line up the copays
you would actually pay.

Daniels Health Advisors is the independent brokerage Paul Daniels founded, licensed in 20 U.S. states. Two plans with the same premium can treat the same visit very differently: one charges a flat copay, the other a percentage after the deductible. We pull the copay or coinsurance for the care you use most from each plan's summary of benefits and set them side by side, for Marketplace plans and, where they fit, private PPO options. Some private plans ask health questions, and approval is not guaranteed. Some may not cover care for health problems you had before you enrolled.

Bring a rough count of last year's doctor visits, your prescriptions, and any surgery or scan you expect in the year ahead.

Before a big bill

Ask about the price
before the procedure.

Coinsurance is why one bill can be much larger than you expected. Before a planned surgery or scan, confirm the provider is in your plan's network and ask what your share of the allowed amount is likely to be. If you pay for care without using insurance, providers usually must give you a good faith estimate when you schedule in advance or ask for one. After the call you will have:

Each plan's copay for the visits you make
The coinsurance rate for hospital care
Which costs wait on the deductible
Your out-of-pocket limit for the year

A checklist for

Reading copays and coinsurance.

Get the summary of benefits and coverage for each plan and find the costs listed by type of care.
Note whether each copay applies before or after the deductible.
Try the coinsurance rate on a realistic bill, such as a hospital stay, not just a $100 visit.
Make sure the out-of-pocket maximum is an amount you could pay in a hard year.

Copay and coinsurance questions

Copay and coinsurance FAQ.

What is coinsurance in health insurance?

Coinsurance is the percentage of a covered service's cost that you pay, usually after you meet your deductible. With 20% coinsurance, you pay 20% of the allowed amount and the plan pays 80%, until you reach your out-of-pocket maximum.

What is a copay?

A copay, or copayment, is a fixed dollar amount you pay for a covered service, such as $20 for an office visit. Depending on the plan and the service, it may apply before or after you meet the deductible.

Is a copay or coinsurance better?

Neither wins in every case. A copay is predictable. Coinsurance can cost about the same on a small bill and far more on a large one. Compare the services you expect to use and each plan's out-of-pocket maximum.

Do copays count toward the deductible?

That depends on the plan, so check its summary of benefits. What doesn't change is that copays and coinsurance for covered in-network care count toward your out-of-pocket maximum.

What does 0% coinsurance after the deductible mean?

It means that once you meet the deductible, the plan pays the full allowed amount for that covered service. Some plans still charge copays for certain services, so read the summary to see how yours works.

Do I have to wait for open enrollment?

Not for every plan. A private plan (not from the Marketplace) can often be bought any time of year. Some private plans ask health questions, and approval is not guaranteed. Some may not cover care for health problems you had before you enrolled. Marketplace plans, and other plans that follow ACA rules, work differently. As of November 1, 2026, under current law, open enrollment for 2027 plans on HealthCare.gov runs from November 1, 2026, to January 15, 2027. To start coverage January 1, pick a plan by December 15. States that run their own Marketplace may set different dates, so check with your state's Marketplace. A federal appeal about these rules is pending (City of Columbus v. Kennedy, 4th Cir. No. 26-1938; argued October 30, 2026, with no ruling as of November 1, 2026), so confirm the dates before you enroll. Outside open enrollment, you need a special enrollment period, such as one after losing job-based coverage.
