PR-1 Denial Code: Deductible Amount
PR-1 means Deductible Amount: the payer applied the allowed amount (or part of it) to the patient's unmet annual deductible. It is not a denial of coverage — the claim processed correctly, and the PR group code makes the amount billable to the patient. No appeal applies.

What does PR-1 mean on a remittance?
PR-1 is the simplest code on the CARC list — official X12 text: "Deductible Amount." The payer adjudicated the claim, applied its contracted allowed amount, and assigned some or all of it to the patient's unmet deductible. Nothing failed. The PR group code means the balance moves to patient responsibility.

Why does PR-1 happen?
The patient has not met their annual deductible yet. Mini-example: a new patient visit bills $180, the payer allows $126.40, pays $0, and the ERA shows PR-1 for $126.40. You write off the $53.60 contractual difference (CO-45) and bill the patient $126.40 — not $180. Expect PR-1 volume to spike every January and after employer plan renewals, when accumulators reset.
How do you work a PR-1?
- Post the payer's adjudication exactly as the ERA shows: contractual adjustment first, then the PR-1 amount to the patient bucket.
- Generate the patient statement promptly — collection probability drops steeply after 90 days.
- If the patient disputes it, verify the accumulator with the payer before adjusting anything.
Can you prevent or appeal PR-1?
There is nothing to appeal — the code is working as designed. The management play is collection timing: verify benefits up front, collect estimated deductible amounts at the point of service where state law and contracts allow, and make sure statements clearly say "applied to your deductible" so patients do not call thinking the claim was denied. If a PR-1 shows up with unfamiliar companion codes, decode the full line in the denial code lookup before calling the payer.
Frequently asked questions
Yes — that is exactly what the PR group code authorizes. Bill the patient the amount shown against PR-1, which is based on the payer's allowed amount, not your full charge. In-network providers cannot bill the difference between the charge and the allowed amount on top of it.
Early in the plan year, most patients have not met their deductible, so the entire allowed amount transfers to patient responsibility until the accumulator is satisfied. High-deductible plans make this routine: a $1,500 claim can be 100% patient responsibility in January and 100% payer-paid in November.
Ask for their EOB or portal accumulator screenshot, then call the payer to compare accumulator totals. Claims from other providers can post out of order, and family versus individual deductibles get crossed. If the payer confirms the deductible was met, they reprocess — no formal appeal needed.
