PR 1 denial code

What PR-1 means

PR-1 is not a denial. It tells you the payer processed the claim, calculated the allowed amount, and applied some or all of it to the patient’s deductible (the amount the patient must pay out of pocket each benefit period before the plan starts paying). The group code PR means patient responsibility: this money is collectible from the patient.

A new biller’s most important habit here is separating the two adjustments on the remittance. Example: billed $150, allowed $100. You will see a contractual adjustment (typically CO-45) for $50, and PR-1 for $100 with a $0 payment. The patient owes $100, never the $150 billed charge. In-network contracts require you to write the difference off.

For Medicare Part B, the deductible is an annual amount set each year (check cms.gov for the current figure), and most claims early in the year show PR-1 until patients meet it.

Common causes

PR-1 is routine, but these situations generate questions:

1. Start of the benefit year: deductibles reset in January for most plans, so first-quarter remittances are heavy with PR-1.
2. High-deductible health plans: patients may hit PR-1 on every visit for months.
3. New coverage mid-year: a fresh deductible starts with the new plan.
4. Split application: part of the allowed amount goes to PR-1, the rest is paid and hits PR-2 coinsurance.
5. Errors worth catching: the payer applied a deductible the patient had already met (often because another provider’s claim posted later), or applied a deductible to a service that should be exempt, such as certain preventive services. Verify against the payer’s records before assuming the remittance is right.

How to fix and resubmit

Usually there is nothing to resubmit. The workflow is posting and collecting:

1. Post the contractual adjustment (the CO-coded amount) to zero out the difference between billed and allowed.
2. Post the PR-1 amount to patient responsibility and move the balance to the patient statement cycle.
3. Reconcile against eligibility: a 270/271 response or payer portal check shows deductible met-to-date. If the payer double-counted, call and request reprocessing rather than billing the patient.
4. If the service should have bypassed the deductible (for example, a preventive service coded correctly under the plan’s rules), confirm the coding, correct if needed, and resubmit; otherwise ask the payer to reprocess.
5. For Medicare patients with Medigap or Medicaid secondary coverage, the deductible amount usually crosses over automatically. Do not bill the patient until the secondary adjudicates; the OA-23 mechanics on the secondary remittance will show what happened.

How to prevent it

You cannot prevent deductibles, but you can prevent surprises and write-offs:

• Run eligibility before the visit and capture deductible remaining from the 271 response or payer portal. Tell the patient the estimate up front.
• Collect at time of service where your payer contracts allow it. Deductible dollars are far easier to collect on the day of the visit than 45 days later.
• Flag secondary coverage during registration so PR-1 balances route to the secondary payer instead of straight to a patient statement.
• Train front-desk staff on what a deductible is; a patient who understands why they owe money pays faster and complains less.
