The three costs, in plain English

Health Insurance has a vocabulary problem. Copay, coinsurance, deductible, out-of-pocket maximum — the words all sound alike, they all describe money leaving your pocket, and plan summaries rarely stop to explain how they fit together. If you have ever stared at a plan listing on HealthCare.gov and wondered what you would actually pay in a bad year, this page is for you.

Here is the shortest honest version. A copay is a flat fee. Coinsurance is a percentage split. And the out-of-pocket maximum is the ceiling on the whole thing — the most you can be required to pay for covered, in-network care in a plan year before your plan pays 100%. Everything below builds on those three sentences.

Copays: the flat fee

A copay (short for copayment) is a fixed dollar amount you pay for a specific service at the time you use it — a primary care visit, a specialist visit, an urgent care trip, or a prescription refill. The amount is spelled out in your plan documents and often printed right on your insurance card.

Copays are the easiest cost to live with because they are predictable: you know before you walk in the door roughly what the visit will cost. On many plans, certain copays apply even before you have met your deductible — a common setup is a flat copay for regular doctor visits while bigger services still count against the deductible first. Every plan draws that line a little differently, which is why the Summary of Benefits and Coverage document is worth a careful read before you enroll, not after.

Coinsurance: the percentage split

Coinsurance works differently. Instead of a flat fee, you pay a percentage of the allowed cost of a service, and your plan pays the rest. Coinsurance typically kicks in after you have met your deductible for the year.

To illustrate the structure only — this is not a quote from any plan — a plan might pay 80% of covered costs after the deductible while you pay the remaining 20%. On a routine office visit that percentage is manageable. On a large hospital bill, it can add up fast, which is exactly why the third piece of the puzzle exists.

The out-of-pocket maximum: your ceiling

The out-of-pocket maximum (sometimes called the out-of-pocket limit) is the most you can be required to pay during a plan year for covered, in-network care. Your deductible payments, copays, and coinsurance all count toward it. Once your combined spending reaches the cap, your plan pays 100% of covered, in-network services for the rest of the plan year.

This single number answers the question that actually matters when you compare plans: if something truly serious happens — a cancer diagnosis, a car accident, a premature baby — what is the worst-case number for your household this year? For covered, in-network care, the out-of-pocket maximum is that number.

How the four costs work together across a year

It helps to see the sequence as stages of a plan year:

  • Stage 1 — you pay your premium no matter what. Your monthly premium is the price of keeping the policy active. It is completely separate from the costs below, and it never counts toward your deductible or your out-of-pocket maximum.
  • Stage 2 — before the deductible. Early in the year, you pay most non-preventive costs yourself (at the plan’s negotiated rates), plus any copays your plan applies. This spending counts toward both your deductible and your out-of-pocket maximum.
  • Stage 3 — after the deductible. Once you have met the deductible, your plan starts sharing costs. You pay coinsurance and any remaining copays; the plan pays the rest.
  • Stage 4 — after the out-of-pocket maximum. When your deductible, copays, and coinsurance together reach the plan’s out-of-pocket maximum, you are done paying for covered, in-network care. The plan pays 100% for the remainder of the plan year.

Most people never reach Stage 4 in a given year, and that is a good thing. But the cap is not there for average years — it is there for the year everything goes wrong. It converts an open-ended financial risk into a defined one, and that is the heart of what Health Insurance actually does for you.

What counts toward your out-of-pocket maximum — and what never does

This is where most of the confusion, and most of the unpleasant surprises, live — so it is worth being precise.

These payments count toward the cap:

  • Everything you pay toward your deductible for covered services
  • Copays for covered, in-network services and prescriptions
  • Coinsurance for covered, in-network services

These payments do not count:

  • Your monthly premiums. Premiums are the price of having the plan, not a shared medical cost. They never count toward the deductible or the out-of-pocket maximum.
  • Care your plan does not cover. If a service is excluded from your plan, what you spend on it does not move you toward the cap.
  • Out-of-network care, in many plans. Some plans — especially HMOs — simply do not cover non-emergency out-of-network care at all. Plans that do cover it often track a separate, higher out-of-network limit. Which type you have matters; our guide to HMO vs. PPO plans walks through the difference.
  • Amounts billed above the plan’s allowed amount. If an out-of-network provider charges more than your plan’s approved rate, the difference generally does not count either.

The practical takeaway: your out-of-pocket maximum is a powerful protection, but it protects you fully only when you stay in network for covered services. Confirming that your doctors and your preferred hospital are in a plan’s network before you enroll is not a nice-to-have — it is the whole ballgame.

The 2026 out-of-pocket limits

Federal law puts a hard ceiling on how high any Marketplace or other ACA-compliant plan can set its out-of-pocket maximum. For plan year 2026, that legal ceiling is $10,600 for an individual (self-only coverage) and $21,200 for a family plan. Those are the highest in-network limits any ACA-compliant plan sold in North Carolina — or anywhere in the country — is allowed to carry in 2026.

Two things to keep straight about those numbers:

  • They are ceilings, not typical values. Plans are free to set lower out-of-pocket maximums, and many do. The federal limit is the worst a compliant plan is allowed to be, not what you should expect to see on every plan card.
  • A separate, lower limit applies to HSA-qualified plans. If you have a high-deductible health plan (HDHP) that qualifies for a health savings account, IRS rules for 2026 cap its out-of-pocket maximum at $8,500 for self-only coverage and $17,000 for family coverage, and require a deductible of at least $1,700 (self-only) or $3,400 (family). The IRS HDHP limits and the ACA limits are two different rules with two different sets of numbers — a plan can only be HSA-qualified if it stays inside the stricter IRS figures.

A hypothetical example: one hospital stay, start to finish

The numbers in this example are invented for illustration only. They are not quotes, averages, or figures from any real plan — your own plan documents are the source of truth for your costs.

Meet a hypothetical Charlotte homeowner we will call Dana. Dana’s plan has a $3,000 deductible, 20% coinsurance after the deductible, and a $9,000 out-of-pocket maximum. In March, Dana needs surgery, and the plan’s allowed amount for the whole episode of in-network care comes to $40,000.

  • Deductible first: Dana pays the first $3,000 of allowed costs.
  • Coinsurance next: of the remaining $37,000, Dana’s 20% share would be $7,400.
  • The cap steps in: $3,000 plus $7,400 comes to $10,400 — but Dana’s out-of-pocket maximum is $9,000. Dana’s payments stop at $9,000, and the plan pays everything above that.
  • The rest of the year: Dana has hit the cap, so every covered, in-network service through December 31 — follow-up visits, physical therapy, prescriptions the plan covers — is paid 100% by the plan.

Notice what did not count: Dana’s monthly premiums, which continue all year, and anything Dana might have spent out of network. And notice what the cap accomplished — it turned a $40,000 medical event into a defined, survivable number.

Preventive care usually costs $0 — even before the deductible

One piece of good news that surprises people: under the ACA, most Health Insurance plans must cover a defined set of preventive services — screenings, immunizations, and similar care — at no copay and no coinsurance, even if you have not touched your deductible, as long as you use an in-network provider. HealthCare.gov does caution that $0 cost is not guaranteed in every case (a preventive visit that turns diagnostic can be billed differently), but as a rule, routine prevention should not be the thing standing between you and your doctor.

Where to find these numbers for your own plan

You do not have to guess at any of this. Every ACA-compliant plan publishes a Summary of Benefits and Coverage — a standardized, plain-language document that lists the deductible, the copay for each common service, the coinsurance percentage, and the out-of-pocket maximum in the same order for every plan, so you can lay two summaries side by side and compare line by line. On HealthCare.gov, those numbers appear on each plan’s detail page while you shop, before you commit to anything.

If you already have coverage, your insurance card usually shows your copays, and your carrier’s member portal tracks a running total of how much you have paid toward your deductible and your out-of-pocket maximum this year. Checking that running total before a planned procedure is one of the simplest money-saving habits in all of Health Insurance — if you are close to the cap, the timing of care within the same plan year can change what you owe.

Using these numbers to compare plans

When you shop the Marketplace, it is tempting to sort by monthly premium and stop there. Resist that. Premiums, deductibles, copays, coinsurance, and the out-of-pocket maximum are one connected system, and plans balance them differently:

  • A lower premium usually means higher cost-sharing. Bronze-level plans tend to pair the lowest premiums with the highest deductibles and out-of-pocket maximums; Gold plans generally do the reverse. Neither is automatically better — it depends on how much care you expect to use and how much risk your budget can absorb in a bad year.
  • Deductibles have been rising. Nationally, KFF’s data on 2026 Marketplace coverage shows the average deductible jumped 37% this year, from $2,759 to $3,786. That makes the out-of-pocket maximum — and the copay structure before the deductible — more important to compare, not less.
  • Your income can shrink these numbers dramatically. If your household income is between 100% and 250% of the federal poverty level — for 2026, up to $39,125 for a single person or roughly $80,375 for a family of four — cost-sharing reductions can lower your deductible, copays, coinsurance, and out-of-pocket maximum. The catch: they only apply if you enroll in a Silver plan. Many people who qualify never find that out on their own.
  • The network shapes the protection. Because the out-of-pocket maximum fully protects only in-network care, a plan’s network — and whether it is an HMO or a PPO — belongs in the comparison from the very start.

For 2026, six insurers offer individual Marketplace plans in North Carolina, and which of them serve your county varies — shoppers around Charlotte in Mecklenburg, Union, Cabarrus, and Gaston counties will not necessarily see the same lineup. The reliable way to know is to preview plans for your own ZIP code at HealthCare.gov.

One more note for anyone approaching 65: everything on this page describes individual and employer Health Insurance. Medicare works differently — Original Medicare on its own has no built-in yearly out-of-pocket cap, which is one of the first things to understand when you cross over. Our plain-English guide to what Medicare is and how it works is the place to start.

How The Jordan Insurance Agency helps

The Jordan Insurance Agency is an independent insurance agency based in Charlotte, North Carolina, serving clients across the state. Because we are independent, we are not tied to a single carrier — we can put plans from multiple insurers side by side and compare the numbers that actually determine what a bad year costs you: the deductible, the copay structure, the coinsurance percentage, and above all the out-of-pocket maximum, checked against the doctors and hospitals you already use.

Here is the part people find hardest to believe: working with a licensed agent costs you nothing. Agents are paid by the insurance carriers, and your premium is exactly the same whether you enroll through an agent or entirely on your own. You are not paying extra for the help — you are simply choosing whether to navigate the fine print alone.

ACA and Marketplace plans are enrolled through HealthCare.gov, and The Jordan Insurance Agency can handle that enrollment with you at no cost. If you would like a local guide who will translate copays, coinsurance, and out-of-pocket maximums into a plain answer about which plan fits your family and your budget, reach out to The Jordan Insurance Agency. No pressure, no jargon — just an honest comparison.
