Cost-sharing, explained

Copay, coinsurance, deductible & out-of-pocket max

Every eligibility check comes back with the same four numbers, and the whole point of verifying is knowing what to do with them. This is the front-desk and billing guide: what each one means, how they interact, and how to turn a benefits response into the right amount to collect — before the patient is standing at the window.

The short version. A copay is a flat dollar amount for a visit. A deductible is what the patient pays first, before the plan starts sharing covered costs. Coinsurance is the patient's percentage share after the deductible is met. The out-of-pocket maximum is the yearly ceiling — once it's reached, the plan pays 100% of covered in-network care for the rest of the plan year. At check-in you collect the copay if the plan has one for that visit type; otherwise what you collect depends on whether the deductible is met and whether coinsurance applies.

The four numbers, defined

Copay (copayment)

A fixed dollar amount for a specific service — say $40 for a specialist visit or $25 for primary care. It's predictable, which is why it's the easiest thing to collect at the desk. Two things to check on the benefits response: (1) whether the copay is per visit type (specialist copays are usually higher than primary-care copays), and (2) whether the plan says the copay applies before or after the deductible — most copays are due regardless of the deductible, but some high-deductible plans make certain services subject to the deductible first.

Deductible

The amount the patient pays out of pocket for covered services before the plan begins to pay. If a plan has a $1,500 deductible and the patient has paid $400 so far this year, they have $1,100 remaining. That "met vs. remaining" split is the number that actually matters at the desk — a benefits response that only shows the total deductible without the amount met tells you almost nothing. Note that deductibles are based on the payer's allowed amount, not your billed charge, and that preventive services are often exempt.

Coinsurance

The patient's percentage share of the allowed amount after the deductible is met — commonly 20%, with the plan paying the other 80%. Coinsurance is why you can't always quote an exact dollar figure up front: 20% of the allowed amount depends on the contracted rate for the specific service. When a plan is coinsurance-based (rather than copay-based), collecting at check-in is a judgment call — many practices collect an estimate and reconcile after the claim adjudicates.

Out-of-pocket maximum

The yearly cap on what the patient can pay in cost-sharing for covered in-network care. Once copays, deductible and coinsurance add up to the out-of-pocket max (for example $6,000), the plan pays 100% of covered in-network services for the rest of the plan year — so the correct amount to collect becomes $0. Premiums never count toward it, and out-of-network costs usually accumulate separately.

What to collect at check-in

Reading the four numbers in the right order turns them into one decision:

1

Is the out-of-pocket max already met?

If yes, collect $0 for covered in-network services — the plan is paying everything. This is easy to miss and a common source of patient refunds.

2

Does the plan have a copay for this visit type?

If yes, collect the copay (specialist vs. primary care as applicable) — unless the response explicitly says the copay is subject to the deductible.

3

No copay — is the deductible met?

If the deductible is not met, the patient may owe the full allowed amount for the visit toward it. If it is met, collect the coinsurance percentage of the allowed amount.

4

Always read the in-network column.

If you're a participating provider, every figure you quote comes from the in-network benefits. In- and out-of-network deductibles and coinsurance can differ by hundreds of dollars.

Where these numbers come from

All four appear in the payer's eligibility and benefits response — the same 270/271 inquiry you run in each portal. The trick is that every portal lays them out differently, and each one hides the "met vs. remaining" detail in a different place. Our payer guides show exactly where to find active status, plan, copay, deductible and out-of-pocket in each one:

Collecting the right amount for a whole schedule

Reading four numbers per patient is quick; doing it for a full day's schedule across five portals is hours of work — and the "met vs. remaining" details are exactly what gets skipped when staff are rushed. That's the work VeriPhy Health automates: it signs in with your own credentials, runs every patient on the schedule through the right portal, and saves a results sheet with copay, deductible and out-of-pocket per patient — plus a benefits PDF — on your own machine.

Common questions

What's the difference between a copay and coinsurance?

A copay is a fixed dollar amount for a service (for example $40 for a specialist visit). Coinsurance is a percentage of the allowed amount (for example 20%) that the patient pays after the deductible is met. A plan usually uses one or the other for a given service, and the eligibility response tells you which.

Do copays count toward the deductible?

Usually no — copays are typically separate from the deductible, though they generally do count toward the out-of-pocket maximum. Some high-deductible plans make certain services subject to the deductible first. The benefits response states how the specific plan treats it.

What happens after the out-of-pocket maximum is met?

The plan pays 100% of covered in-network services for the rest of the plan year, so the patient's cost-sharing for those services is $0. Premiums and non-covered services don't count toward the maximum.

Should I collect coinsurance at check-in?

Coinsurance is a percentage of the allowed amount, so the exact dollar figure isn't known until the claim adjudicates. Many practices collect an estimate based on the contracted rate and reconcile afterward, rather than collecting a copay-style flat amount.

Written from daily, hands-on eligibility work, September 2026. This is general cost-sharing guidance, not plan-specific advice — the exact copay, deductible, coinsurance and out-of-pocket figures always come from the individual plan's benefits response for the date of service.
