PR-2: Amount applied to the patient's coinsurance

PR-2 is a normal cost-sharing adjustment, not a denial. After the deductible is met, most plans split the allowed amount between payer and patient by percentage; PR-2 is the patient's share. It appears alongside the payment rather than instead of it. The number worth checking is the percentage: coinsurance is calculated against the allowed amount, never the billed charge, and billing a percentage of the charge is one of the more common patient-billing errors.

What it means
The patient owes a percentage of the allowed amount under their plan's cost-sharing terms.
Who pays the balance
Patient responsibility - this balance is billable.
Group code PR
Patient Responsibility - the balance transfers to the patient

Why PR-2 happens

How to fix a PR-2 denial

  1. 1

    Confirm the percentage matches the plan

    Divide the PR-2 amount by the allowed amount and compare it to the plan's stated coinsurance percentage. A mismatch usually means the claim priced out-of-network unexpectedly, which is a participation or credentialing problem rather than a patient-billing one.

  2. 2

    Bill the coinsurance shown on the remittance, not a percentage of your charge

    Coinsurance is a share of the contracted allowed amount. Calculating it from the billed charge overbills the patient and violates the contract, and it is a frequent source of refund requests and complaints.

  3. 3

    Check the out-of-pocket maximum before pursuing an aged balance

    If the patient has since met their out-of-pocket maximum, later claims will process without coinsurance, and a reprocessing of this claim may be warranted if the maximum was already met on the date of service.

Preventing PR-2 denials

PR-2 frequently asked questions

What does denial code PR-2 mean?
PR-2 means the amount is the patient's coinsurance - their percentage share of the allowed amount under the plan's cost-sharing terms. It is patient responsibility and is billable.
What is the difference between PR-1, PR-2, and PR-3?
PR-1 is the deductible, PR-2 is coinsurance (a percentage of the allowed amount), and PR-3 is a copayment (a flat per-visit amount). All three are patient responsibility; they differ in how the patient's share is calculated.
