PR-1 means the payer applied the amount to the patient's deductible. It is not a denial in the usual sense: the claim was processed correctly, and the patient now owes that amount (or their secondary insurance does). The work is billing it correctly and collecting it, not appealing it.
1. What PR-1 means
- PR (Patient Responsibility): the amount can be billed to the patient or to a secondary payer.
- 1: deductible amount.
The payer allowed the service, then applied some or all of the allowed amount to the patient's deductible. PR-1 balances spike early in the plan year, when deductibles reset. For most plans that is January.
2. PR-1, PR-2, and PR-3
| Code | Meaning | Who owes it |
|---|---|---|
| PR-1 | Deductible amount | Patient, or secondary coverage |
| PR-2 | Coinsurance amount (a percentage of the allowed amount) | Patient, or secondary coverage |
| PR-3 | Copayment amount (a fixed amount) | Patient, or secondary coverage |
All three are patient responsibility. If a line shows CO adjustments as well, such as CO-45 for the amount above the contracted rate, those are provider write-offs and must not be billed to the patient.
3. What to do with a PR-1 balance
- Check for secondary coverage. If the patient has a secondary plan, send the claim there with the primary payer's remittance details. Medicare often forwards claims to supplemental insurers automatically (crossover); remark code MA18 tells you it did.
- Post it as patient responsibility for exactly the PR-1 amount on the remittance, not the full charge.
- Apply any payment collected at the visit before sending a statement.
- Send a clear statement that explains the deductible in plain language and offers online payment and payment plans.
4. When PR-1 is wrong
- The patient already met the deductible but the payer's tracking lagged behind other claims. Call the payer and ask for reprocessing.
- The wrong plan was billed, for example an old plan with a different deductible, or the plans in a coordination of benefits situation were billed in the wrong order.
- The service should not be subject to the deductible. Many plans cover preventive services with no cost sharing. If a preventive visit was coded as diagnostic, the deductible may have been applied incorrectly.
5. Collecting deductibles without chasing them
- Check remaining deductible at eligibility. The 271 eligibility response usually reports deductible and out-of-pocket remaining. Our eligibility verification guide covers how to read it.
- Give an estimate before the visit and collect a deposit for higher-cost services.
- Keep a card on file with patient consent, to charge the remaining balance once the remittance arrives.
- Watch patient AR separately from insurance AR. Patient balances age differently and need their own follow-up rhythm. See our days in AR guide.
6. Where automation helps
PR-1 lines do not need appeals, but they do need routing: secondary claim, patient statement, or reprocessing request. Automation can read every remittance, route each PR line to the right next step, flag deductibles that look wrong against the eligibility data, and keep patient balances moving before they age.
