PR-2 Denial Code: Coinsurance Amount Explained

The PR-2 denial code is not a denial at all — it is the coinsurance amount the patient owes after the payer adjudicates the claim under their plan benefits. The PR (Patient Responsibility) group means the balance moves to the patient rather than becoming a provider write-off. Reason code 2 simply reports the patient's percentage share of the allowed amount, so the right next step is billing the patient or the secondary plan, not filing an appeal.

What is the PR-2 denial code? PR-2 pairs Claim Adjustment Reason Code 2 — Coinsurance Amount — with the Patient Responsibility group, indicating the portion of the allowed amount the patient owes as their cost-share after the plan pays its percentage.

Bottom Line

PR-2 is money you are owed, not money you lost — and the most expensive mistake is treating it like a denial. On a remittance summary, PR-2 sits in the same column as real denials, so busy billing teams sometimes write it off or let it age instead of moving it to the patient or the secondary payer. That is revenue walking out the door over a misread group code. The discipline is mechanical: when you see PR, the balance is the patient's, so post it, check for a secondary plan that should pick it up, and send the statement. The only time PR-2 warrants an appeal is when the coinsurance was applied to a service that should have been paid in full — then the dispute is with how the plan adjudicated it.

What PR-2 Means

PR-2 reflects the patient's coinsurance — the fixed percentage of the allowed amount their plan requires them to pay after the payer applies its share. It is a normal, correct adjudication outcome, not an error or a rejection. The PR group code assigns the amount to the patient, distinguishing it from contractual write-offs (CO group) the provider absorbs and from other adjustments (OA group).

Coinsurance vs Deductible vs Copay

The three patient-responsibility codes describe different cost-sharing. PR-1 is the deductible — the fixed amount the patient pays before coverage begins. PR-3 is the copay — a flat per-visit charge. PR-2 is coinsurance — a percentage of the allowed amount the patient pays alongside the plan. A single claim can carry more than one of these, so read each PR line to assemble the full patient balance.

Why PR-2 Appears

• The patient's plan requires coinsurance on the service, and the claim was adjudicated correctly.
• The deductible was met, so the remaining cost-share shifts to the coinsurance percentage.
• The service is covered but subject to the plan's standard cost-sharing.
• A secondary plan may still pick up part or all of the coinsurance if one exists.

How to Handle a PR-2

1. Confirm the coinsurance percentage matches the patient's plan benefits and the allowed amount.
2. If the patient has secondary coverage, bill the secondary plan before billing the patient.
3. Post the remaining balance to the patient and send a statement.
4. Only if the coinsurance was applied to a service that should have been paid in full, gather the plan documents and appeal — or draft it with the appeal generator.

Frequently Asked Questions

What does PR-2 mean?

PR-2 is the coinsurance amount the patient owes after the plan pays its share — a percentage of the allowed amount assigned to patient responsibility. It is a normal adjudication outcome, not a denial of the service.

Is PR-2 a denial I should appeal?

Usually not. PR-2 reports patient cost-sharing, so the correct step is billing the secondary plan or the patient, not appealing. Appeal only if the coinsurance was applied to a service that should have been paid in full.

What is the difference between PR-2 and PR-1?

PR-2 is coinsurance — a percentage of the allowed amount. PR-1 is the deductible — a fixed amount the patient pays before coverage begins. Both are patient responsibility, and a claim can show both at once.

Can I bill the patient for a PR-2 amount?

Yes. PR-2 carries the Patient Responsibility group, so the coinsurance is billable to the patient after any secondary plan has been billed. Verify the amount against the plan's cost-sharing before sending the statement.
