The short answer is that your copay may not be the full cost. For covered, in-network care, start with the health plan's allowed amount. Then apply the plan's copay, remaining deductible, or coinsurance rules to that amount. Tests, imaging, procedures and facility charges may be calculated separately.
Calculation basics
Start with the allowed amount, not the billed charge
A provider's billed charge and the health plan's negotiated amount can be different. For an in-network provider, your cost sharing is generally calculated from the plan's allowed amount.
The allowed amount may also be called the negotiated rate, eligible expense, or payment allowance. You can often find it in the plan's online cost estimator or on an explanation of benefits after the claim is processed.
Outside the network, the plan may recognize only part of the charge, and the provider may be allowed to bill you for more.
Plan rules
Determine which type of cost sharing applies
The Summary of Benefits and Coverage shows how common services are handled. Find the row for primary care, specialist care, urgent care, or the service you expect to use.
A fixed amount for a covered service, such as $20 for an office visit. Your plan documents determine whether the copay applies before or after the deductible.
A percentage of the allowed amount that you pay, such as 20%. Coinsurance commonly begins after you meet the deductible, but the plan documents control.
If the row says "deductible does not apply," the listed copay or coinsurance may apply before you meet the deductible. If it says "after deductible," you may have to satisfy some or all of the deductible first.
Worked examples
Use the rule that matches your situation
The examples below use figures from HealthCare.gov's cost-sharing examples: a $125 office visit, a $1,500 deductible, 20% coinsurance, and a $5,000 out-of-pocket maximum.
What you may pay for a $125 covered in-network visit
| Your situation | Calculation | Estimated cost |
|---|---|---|
| A $20 office visit copay applies | Fixed copay | $20 |
| Subject to the deductible, more than $125 remaining | You pay the $125 allowed amount | $125 |
| You meet the deductible during the visit | Remaining deductible, then coinsurance on the rest | Use the formula below |
| The deductible is met and 20% coinsurance applies | $125 × 20% | $25 |
| The in-network out-of-pocket maximum is met | The plan pays for additional covered in-network care | $0 |
These are simplified illustrations, not price estimates. Your Summary of Benefits and Coverage, current deductible balance, provider network status and processed claim determine the actual amount.
1. A copay applies
If your plan lists a $20 copay for a covered office visit and the deductible does not apply, your basic visit cost is $20. The plan pays the rest of the allowed amount. This does not guarantee that the entire appointment costs $20: a blood test or procedure ordered during the visit may generate another claim.
2. You have not met the deductible
Suppose the allowed amount is $125 and the visit is subject to the deductible. If you still have more than $125 left to meet, you pay the full $125 allowed amount, and that payment generally moves you $125 closer to the deductible. The plan may still have negotiated the price even though it does not pay part of this particular claim.
3. You meet the deductible during the visit
When the allowed amount is greater than your remaining deductible, use this formula:
Remaining deductible + ((allowed amount − remaining deductible) × coinsurance rate)
Claims processing and plan design can affect the order, so use the formula to understand the structure rather than to predict a guaranteed bill.
4. You already met the deductible
If the allowed amount is $125 and your coinsurance is 20%, you pay $125 × 20% = $25. The plan pays the remaining $100.
5. You reached the out-of-pocket maximum
After you reach the applicable out-of-pocket maximum, the plan generally pays 100% of additional covered, in-network services for the rest of the plan year. Premiums do not count toward the limit. Care the plan excludes and certain out-of-network charges may not count either.
Preventive care
Some visits may cost $0, but the reason for the visit matters
Many plans cover specified preventive services without a copay or coinsurance when you use an in-network provider, even before you meet the deductible. Coverage varies, and $0 is not guaranteed for every service.
A preventive appointment can also include nonpreventive care. If you discuss a new symptom, receive a procedure, or have testing that is not covered as preventive, part of the appointment may be billed under the plan's regular cost-sharing rules. Before the visit, ask which services are expected and whether the insurer considers them preventive under your exact plan.
Separate charges
One appointment can produce more than one claim
Depending on what happens during the appointment, you may also see separate charges for:
- Laboratory testing. Bloodwork and other tests may use a separate laboratory benefit.
- Imaging. X-rays, ultrasounds, CT scans and MRIs may have their own deductible or coinsurance.
- Procedures. An injection, biopsy or other procedure may be billed in addition to the evaluation.
- Facility charges. Care at a hospital-owned clinic or outpatient department may include a facility component.
- Other clinicians. A radiologist, pathologist, anesthesiologist or other professional may submit a separate claim.
After the claim is processed, compare the provider's bill with the explanation of benefits. The explanation of benefits is not a bill: it shows the charge, allowed amount, plan payment, and the amount assigned to you.
Network effect
Network status can change every part of the calculation
In-network providers have agreed to the plan's negotiated rates. Out-of-network care may use a different allowed amount, a separate deductible, higher coinsurance, or no coverage at all. The provider may also be permitted to bill you for the difference between its charge and the amount recognized by the plan, which is called balance billing.
Federal protections can limit certain out-of-network charges for emergency services and some services received at in-network facilities. They do not apply to every out-of-network service.
How to tell if a doctor is in network, and what out-of-network care can cost
Before the visit
Five things to check before scheduling care
- 1Confirm the provider and location.
Ask the insurer whether the specific clinician and the exact facility address participate in your plan's network.
- 2Find the service in your plan documents.
Check the Summary of Benefits and Coverage for the relevant copay, deductible and coinsurance language.
- 3Check your current balances.
Your insurer's member portal should show how much of the deductible and out-of-pocket maximum you have already met.
- 4Use the plan's cost estimator.
Search for the provider, location and service. If possible, ask the provider for the expected billing code so you are comparing the correct service.
- 5Ask about additional services.
Find out whether laboratory work, imaging, procedures or facility charges are likely to be billed separately.
The final amount can change if different services are performed, the claim uses different billing codes, or the plan excludes a service.
The bottom line
Use the allowed amount, then apply your plan's rules
To estimate a doctor visit, identify the plan's allowed amount, determine whether a copay or deductible applies, and calculate any coinsurance. Then check whether the appointment may generate separate charges.
The math cannot confirm that a service is covered or that every provider involved is in network. Your plan documents, current deductible balance, provider network and processed claim control the final amount.
