Quick answer
Four numbers decide what you pay for care. Your deductible is what you pay first each year before your plan shares costs. Your copay is a fixed amount for a service, like $30 for an office visit. Your coinsurance is your percentage share — often 20% — of bills after the deductible. And your out-of-pocket maximum is the yearly cap: once your spending reaches it, the plan pays 100% of covered in-network care. Your premium, the monthly bill, is separate — it never counts toward any of the four. If you'd rather skip the math, call us: we verify your coverage free and tell you what your visit will cost before you come in.
These are the questions we hear at the front desk every week: "I pay for insurance every month — why do I still owe something today?" "My card says $30 — is that all I pay?" "What does 20% coinsurance even mean?" Nobody is born understanding this vocabulary, and the card in your wallet doesn't explain itself. So let's translate it, one number at a time, and then run a real bill through all four so you can see how they work together.
The five numbers, one by one
Four of these numbers govern what you pay when you use care. The fifth — the premium — is what you pay to have the plan at all, and it plays by different rules.
- Premium — the monthly cost of having coverage. This is the amount you (and often your employer) pay every month to keep your plan active. You owe it whether you see a doctor or not, and it does not count toward your deductible or your out-of-pocket maximum. A plan with a low premium usually makes up for it with a higher deductible; a higher premium often buys that deductible down.
- Deductible — what you pay first. The deductible is the amount you pay for covered care each year before your plan starts sharing the cost. If your deductible is $1,000, the first $1,000 of covered care is on you. It resets every plan year. Some services — preventive care, and often copay-based visits — are handled differently, which we'll get to below.
- Copay — a fixed amount for a service. A copay (or copayment) is a set dollar amount you pay for a specific service: for example, a fixed amount for a primary-care visit, a different one for a specialist, another for a prescription. The appeal is predictability — you know the number before you walk in. Some plans apply copays from day one; others apply them only after the deductible is met. Your card or plan summary says which.
- Coinsurance — your percentage share. Instead of a fixed amount, coinsurance splits a bill by percentage after your deductible is met. At 20% coinsurance, a covered bill of $500 costs you $100 and your plan $400. Coinsurance is where costs get unpredictable, because 20% of a small bill and 20% of a hospital bill are very different numbers.
- Out-of-pocket maximum — your yearly safety cap. This is the most you can be asked to pay in a year for covered, in-network care. Every deductible payment, copay, and coinsurance amount you pay counts toward it. Reach the cap, and your plan pays 100% of covered in-network care for the rest of the year. It is the number that protects you from a truly bad year.
| Number | What it is | When it applies |
|---|---|---|
| Premium | Monthly cost of having the plan | Every month, whether you use care or not |
| Deductible | What you pay first for covered care | Until it's met, each plan year |
| Copay | Fixed amount for a specific service | At the visit or the pharmacy counter |
| Coinsurance | Your percentage share of a bill | After the deductible, on covered bills |
| Out-of-pocket max | Yearly cap on your cost-sharing | Once reached, the plan pays 100% of covered in-network care |
How they work together: one year, step by step
Definitions are easier with arithmetic. The box below uses invented round numbers to show the order the numbers apply in — deductible first, then coinsurance, with the out-of-pocket maximum standing guard over the whole year. One term matters here: the allowed amount, the negotiated price your plan has agreed with the provider. Your percentages apply to that number, not to a sticker price.
Example — for illustration only
This is a made-up plan and made-up bills, shown only to demonstrate the math. These are not Evolve Health prices and not your plan's terms — your own numbers are on your card and plan summary.
The example plan: $1,000 deductible · 20% coinsurance · $4,000 out-of-pocket maximum.
- First visit of the year — a covered service with an allowed amount of $600. Your deductible isn't met, so you pay the $600. You now have $400 of deductible left, and $600 counted toward your out-of-pocket maximum.
- Second visit — a covered service with an allowed amount of $2,000. You pay the remaining $400 of your deductible first. That leaves $1,600 of the bill, and coinsurance splits it: 20% is yours ($320) and 80% is the plan's ($1,280). Your total for this visit: $720. Your running total for the year: $1,320 of the $4,000 cap.
- If the year keeps going — every copay, deductible payment, and coinsurance share keeps adding to that running total. The moment it reaches $4,000, your plan pays 100% of covered in-network care for the rest of the plan year.
Notice what never appeared in the math: the premium. It runs on its own track, every month, regardless of which bills come in.
The preventive care exception
There is one big exception to "you pay first": preventive care. Most plans cover recommended preventive services — including your annual physical — before you have met your deductible, often with no copay at all. It is the plan's way of paying a little now to catch problems early instead of paying a lot later. That is why, at Evolve Health, your annual physical is often $0 with acceptable insurance. Two honest cautions: plans vary in exactly what they count as preventive, and if a checkup turns into treatment — a new problem that needs workup or management — that treatment part may be billed under the regular deductible-and-coinsurance rules. Neither caution is a reason to skip the physical; it is a reason to verify coverage first, which we do free.
Where to find your four numbers
- On the card itself. Many cards print the office-visit and specialist copays right on the front, and some print the deductible too. Flip it over — member services phone numbers and claim details usually live on the back.
- In the Summary of Benefits and Coverage. Every plan must provide this standard document — a short, uniform chart of the deductible, copays, coinsurance percentages, and out-of-pocket maximum, with worked coverage examples. If you enrolled through an employer or the marketplace, it was in your enrollment materials and is posted in your member account.
- In the member portal or app. Your insurer's portal shows your personal numbers, including the most useful figure of all mid-year: how much of your deductible and out-of-pocket maximum you have already met.
- Or just ask us. Reading plan documents is genuinely confusing, and part of our job is translating them. Bring the card — we work from it every day.

Frequently asked questions
What's the difference between a deductible, a copay, and coinsurance?
A deductible is the amount you pay for covered care first, before your plan starts sharing costs. A copay is a fixed amount — say $30 — that you pay for a specific service, like an office visit. Coinsurance is a percentage: after your deductible is met, you might pay 20% of a bill while your plan pays 80%. Many visits use a copay instead of coinsurance, and once you reach your out-of-pocket maximum, the plan pays 100% of covered in-network care for the rest of the year.
What is an out-of-pocket maximum?
It is the most you can be asked to pay in a year for covered, in-network care. Your deductible, copays, and coinsurance all count toward it. Once your spending reaches that cap, your plan pays 100% of covered in-network services for the rest of the plan year. Your monthly premium does not count toward the cap, and neither does care from out-of-network providers or services your plan does not cover.
Does my premium count toward my deductible?
No. Your premium is the monthly amount you pay to keep your coverage active, and it never counts toward your deductible or your out-of-pocket maximum. Think of it as the membership fee: you pay it whether or not you see a doctor, and the cost-sharing numbers — deductible, copay, coinsurance — only start once you actually use care.
Does my annual physical count toward my deductible?
Usually not. Most plans cover recommended preventive care — including your annual physical — before you have met your deductible, and at Evolve Health your annual physical is often $0 with acceptable insurance. Plans vary, though, and if a visit uncovers a problem that needs treatment, that treatment part may be billed separately and counted toward your deductible. We confirm your coverage free before your visit, so you know where you stand.
Where do I find my deductible, copay, and coinsurance amounts?
Start with your insurance card: many cards print the office-visit copay and the deductible right on the front or back. The full picture — deductible, coinsurance percentages, and out-of-pocket maximum — is in your plan's Summary of Benefits and Coverage, a standard document your insurer must provide, and in your insurer's member portal or app. If the numbers are still not clear, call us: with your card, a photo ID, and your date of birth, we verify your coverage free and explain what your visit will cost.
