PR-3 is the Patient Responsibility adjustment for a copayment. The payer approved the service, subtracted the patient’s fixed copay from what it owes, and reported that amount as the patient’s share. It is not a denial, and unlike the other cost sharing codes it is usually money your front desk should have collected before the patient left.
That is what makes PR-3 different from work. Deductible and coinsurance amounts are often unknown until the remittance arrives, but a copay is known in advance. Most PR-3 problems therefore come from a mismatch between what was collected at the visit and what the payer reported. This guide covers what the code means, how payers apply copays to claims, how to reconcile PR-3 against collections, the billing rules that protect your practice, and what changes by payer type.
| PR-3 means copayment, a fixed dollar amount the patient owes for a visit or service. Compare it with what was collected at check in, bill only the unpaid difference, and refund any overpayment. |
What PR-3 Means
PR is the claim adjustment group code for patient responsibility. The number 3 is the Claim Adjustment Reason Code (CARC) that X12 defines as the copayment amount. A copayment is a fixed dollar amount set by the member’s plan for a specific type of visit or service, such as a primary care visit, a specialist visit, urgent care, or an emergency room visit.
PR-3 Is a Reconciliation Item
Because the copay is stated on the member’s card and in the benefit summary, a practice can collect it at check in. When the remittance arrives, PR-3 confirms what the payer expected the patient to pay. Your job is to match it against the receipt. If the two agree, there is nothing to bill. If they do not, the difference is either a small patient balance or a refund.
How It Appears on a Remittance
On the 835 electronic remittance advice, PR-3 sits in a CAS segment with PR as the group code, 3 as the reason code, and the copay amount third. A paid line with a contractual write off and a copay looks like this:
CAS*CO*45*80.00~
CAS*PR*3*30.00~
With a $200 charge and a $120 allowed amount, the payer paid $90. The check is $90 + $80 write off + $30 copay = $200. The $80 write off is provider responsibility.
Why Copays Vary From Visit to Visit
A copay is not one number per plan. It changes with the type of service, the provider, the place of service, and the day’s other claims. Knowing the pattern prevents most collection errors.
| Service or situation | How copays often behave | What to check |
| Primary care visit | Lowest copay tier on most plans | Provider type and specialty on the claim |
| Specialist visit | Higher copay than primary care | Whether the plan treats the provider as a specialist |
| Urgent care | Separate, usually higher copay | Place of service code |
| Emergency room | Highest copay, often waived if the patient is admitted | Admission status and plan rules |
| Telehealth | Same as in person on many plans, waived on some | Plan telehealth benefit |
| Imaging, lab, or procedures | Some plans add a separate copay | Benefit grid for that service |
| Therapy and behavioral health | Per visit copay, often with a visit limit | Visits used and remaining |
| Preventive services | Typically no copay for recommended in network care | Coding and plan type |
| Visits inside a global surgical period | No separate visit to bill, so no copay | Whether the visit is part of the surgical package |
How Payers Apply PR-3 on a Claim
- • One copay per visit. When several service lines share a date, the payer usually applies the copay once, often to a single line such as the evaluation and management code. Do not expect a copay on every line.
- • The copay can be capped at the allowed amount. If the plan copay is $30 but the allowed amount is $25, the patient owes $25 and the plan pays $0.
- • Multiple providers can mean multiple copays. Two separate provider visits on the same day may each carry a copay, depending on the plan.
- • Some plans add coinsurance on top of the copay for certain services, in which case you will also see PR-2 coinsurance adjustments on the line.
- • Some plans apply the deductible before any copay for specific services. In that case the remittance shows a deductible adjustment, and the copay you collected may be only part of what the patient owes. The deductible case is explained in PR-1 deductible adjustments.
- • Visit limits end the copay. When a plan caps yearly visits for therapy or chiropractic care, later visits move to a limit reached reason such as PR-119 benefit maximum reached.
The Core Job: Reconcile PR-3 With What You Collected
Reconciliation is one subtraction. Take the total patient responsibility on the remittance, then subtract what the patient has already paid for that date of service:
Patient balance = PR amounts on the remit – payments collected for that date of service
A positive result is a balance to bill. A negative result is a credit that belongs to the patient. Practices that cannot match front desk receipts to remits quickly often rely on medical billing support that reconcile copay collections with remittances, since the work is small per claim but adds up across hundreds of visits.
Five Reconciliation Scenarios
In each case the plan copay is $30 unless noted. When the collected amount equals PR-3, the balance is $0 and there is nothing more to do.
| Scenario | What the remit shows | Collected at visit | Result |
| Patient underpaid | PR-3 $30 | $20 | Bill $10 |
| Patient overpaid | PR-3 $30 | $40 | Credit of $10 to refund |
| Copay larger than allowed amount | Allowed $25, PR-3 $25, plan pays $0 | $30 | Credit of $5 to refund |
| Deductible applied instead of a copay | PR-1 $120 | $30 | Bill $90; the patient owes $120 in total |
| Preventive visit plus a problem addressed | Preventive line has no cost sharing; the separate problem visit shows PR-3 $30 | $0 | Bill $30 |
The last row is common. When a clinician addresses a separate problem during a preventive exam and reports it with modifier 25, many plans treat the problem oriented visit as a normal office visit and apply the copay to it. The front desk often collects nothing because the visit was scheduled as preventive. If the plan does not cover the routine exam at all, the line is reported separately under PR-49 routine exam code.
Billing Rules for PR-3
- Bill only the unpaid difference. Never send the full PR-3 amount to a patient who already paid part or all of it.
- Refund overpayments promptly. A credit balance belongs to the patient, and payer contracts and state rules often set deadlines for returning it.
- Do not write off PR-3 as a contractual adjustment. The write off is reported under CO-45, and the copay remains the patient’s responsibility.
- Do not bill a copay for a visit that is part of a global surgical package or is otherwise not separately billable. If one was collected, refund it.
- Check Qualified Medicare Beneficiary status before billing copays on Medicare Advantage claims. Federal rules bar billing QMB patients for Medicare and Medicare Advantage cost sharing.
- Apply any waiver or discount through a written financial assistance policy used consistently. Routine copay waivers can violate payer contracts and raise compliance concerns.
PR-3 by Payer Type
Commercial Plans
Commercial plans make heaviest use of copays. They are printed on the member card, so verify them at scheduling and again at check in, and remember that the benefit grid can differ by service even within one plan.
Medicare Advantage and Original Medicare
Original Medicare pays most Part B physician services with 20% coinsurance after the deductible, so PR-3 is uncommon on traditional Medicare claims. Medicare Advantage plans, however, commonly use copays that differ by service category. Do not apply Original Medicare assumptions to an Advantage member.
Medicaid
State Medicaid programs may charge nominal copays for some services, and federal rules exempt certain groups and services from cost sharing. Confirm the state rules before collecting or billing any copay on a Medicaid claim.
When the PR-3 Amount Looks Wrong
Review the amount whenever one of these appears:
- • The copay is higher than the amount printed on the member card for that service.
- • The payer applied a specialist copay to a primary care provider, or the reverse.
- • A copay appears on a preventive service or on a visit inside a global period.
- • More than one copay appears for a single visit that should carry one.
- • The payer cannot match the patient to the policy, which may put the claim under PR-31 patient not identified as insured instead.
Before you contact the payer, collect the eligibility response from the visit, a copy of the member card, the benefit summary, and the claim with its place of service and provider information.
Front Desk Habits That Prevent Copay Problems
- • Verify the copay for the specific service at scheduling and again at check in.
- • Say the amount out loud: “Your copay for today’s visit is $30. Would you like to pay by card or cash?”
- • Give a receipt that lists the date of service, amount, and payment method.
- • Record collections in the patient account the same day so reconciliation is simple.
- • Flag visits where a preventive exam may turn into a problem visit, and tell the patient a copay may apply.
- • Offer payment options in line with your written policy, applied the same way for every patient.
Larger groups usually connect these steps to posting and statements through end to end revenue cycle management for patient payment workflows, so a copay collected at the desk shows up correctly when the remittance is posted.
Measuring Copay Performance
- • Point of service copay collection rate, the share of known copays collected at the visit.
- • PR-3 variance, the gap between PR-3 on remits and copays collected, by payer.
- • Overcollection refunds issued each month and the days to refund them.
- • Patients balance under a set dollar amount, which often come from small copay shortfalls.
If the variance stays high for one payer or one location, the cause is usually a verification or posting habit, and a medical billing audit for copay and patient payment accuracy can find it quickly.

Frequently Asked Questions
Q1- Is PR-3 a denial code?
No. It reports the patient’s fixed copay on a service that was approved and paid.
Q2- What is the difference between a copay and coinsurance?
A copay is a fixed dollar amount. Coinsurance is a percentage of the allowed amount.
Q3- Why does PR-3 appear on only one line of a multi line claim?
Payers usually apply one copay per visit and assign it to a single line.
Q4- Why did the payer pay $0 and still show PR-3?
When the allowed amount is at or below the copay, the patient owes the allowed amount and the plan pays nothing.
Q5- The patient paid a copay but the remit shows a deductible. What now?
Bill the patient the deductible amount minus what was collected. The payer applied the deductible first for that service.
Q6- Can the practice waive a copay?
Not as a routine practice. Use a written financial assistance policy and consult legal counsel.
Q7- Does a copay count toward the deductible?
It depends on the plan. Many plans count copays toward the out of pocket maximum but not the deductible, so check the plan documents.
Q8- What should I do with a copay collected on a visit that was not billable?
Refund it and document the reason.
Conclusion
PR-3 is the most predictable patient responsibility code and the one most directly tied to your front desk. Match it to the receipt, bill only the difference, refund overpayments, and verify the copay for each service before the visit. When the amount does not fit the benefit, work it as a payer error with the right documents behind you.
