What PR-2 means

PR-2 is the coinsurance portion - the percentage of the allowed amount the patient owes after any deductible. It is an adjustment, not a denial. Post it to patient responsibility and bill the patient or secondary payer.

Common causes

  • The plan requires the patient to pay a percentage (for example 20%) of the allowed amount.
  • The service fell under a benefit tier with coinsurance rather than a flat copay.
  • Out-of-network benefits applied a higher coinsurance rate.

How to fix it

  • Post the PR-2 amount to patient responsibility and bill accordingly.
  • Bill any secondary payer, which may cover part or all of the coinsurance.
  • Verify the coinsurance percentage matches the plan if the amount seems incorrect.

How to prevent it

  • Confirm coinsurance rates during eligibility verification.
  • Estimate and communicate patient responsibility before or at the visit.
  • Submit to secondary coverage quickly to reduce patient balances.
No - verify it was applied correctlyPR-2 is a plan cost-share, not a payer error, so there is no denial to appeal - but confirm the coinsurance percentage and amount are correct for the plan; if misapplied, request reprocessing. Then bill any secondary payer and the patient for the balance.
