PR 100 Denial Code - Payment to Patient Explained

Code 100 indicates that the payer has issued the payment directly to the patient, insured, or responsible party, rather than to the provider. This means that the provider will need to collect payment for services directly from the patient or responsible party.

Who Pays: Group Code Liability

For code 100, the group code PR applies, making the amount billable to the patient or responsible party. The provider should not write this off as a contractual adjustment.

Why Claims Get Code 100

  • The patient has a high deductible health plan and the deductible has not been met yet.
  • The payer's policy stipulates that payment for this service goes directly to the patient.
  • Coordination of Benefits (COB) issues where the patient is the primary payer.
  • Incorrect billing information leading the payer to send payment to the patient.
  • The payer's policy requires the patient to pay upfront and seek reimbursement.

How to Fix & Resubmit

  1. Verify with the payer that the payment was indeed sent to the patient or responsible party.
  2. Check the patient's insurance policy details to understand if direct payment is standard for this plan.
  3. Contact the patient to confirm receipt of payment and arrange for them to pay the provider.
  4. Update the patient's account to reflect the balance due and send a bill if necessary.
  5. If the payer sent the payment in error, request a reversal and reissue of payment to the provider.

Corrected Claim or Appeal?

For code 100, a corrected claim is not applicable as the payment was directed to the patient. An appeal is not generally appropriate unless the payer's policy was incorrectly applied; in such cases, verify payer rules before proceeding.

Preventing Future 100 Denials

  • Confirm the patient's insurance policy regarding direct payments at registration.
  • Ensure accurate COB information is on file to avoid payment misdirection.
  • Educate patients about their responsibilities if their plan pays them directly.
  • Regularly review payer policies to understand when direct payments to patients occur.
