Payment Made to Patient/Insured/Responsible Party

What it means

The insurance company sent the payment directly to the patient (or the policyholder/responsible party) instead of to your practice. This usually happens with out-of-network claims or plans where reimbursement is contractually directed to the member rather than the provider.

Common causes

Provider is out-of-network and the payer's policy routes payment to the member
No valid assignment of benefits on file for the claim
Patient's plan is structured to reimburse the subscriber rather than the rendering provider
Claim was submitted without an assignment of benefits indicator or authorization
Payer records show the patient as the payee of record from a prior update or enrollment

How to fix it

Confirm whether an assignment of benefits (AOB) form was signed and on file for this patient/date of service
Check the remittance advice to verify the payment amount and to whom it was issued
If in-network, contact the payer to ask why payment bypassed assignment of benefits and request correction or reissue
If out-of-network, contact the patient to collect the payment they received, per your office's financial policy and any prior payment agreement
Update your system to flag the account as patient-responsible for collection of that payment amount
For future claims, ensure AOB forms are obtained and submitted correctly if you want payments directed to the practice

Appeal / resubmit

Appeals for code 100 are typically limited if the payer correctly followed plan terms directing payment to the member. If you believe an assignment of benefits was on file and should have been honored, submit a written request to the payer including a copy of the signed AOB and ask for reprocessing. Include a copy of the remittance advice and any prior correspondence confirming assignment status.

Frequently asked

Does code 100 mean the claim was denied?

Not exactly — it means the payer processed the claim and issued payment, but sent that payment to the patient or policyholder instead of the provider.

Can I still bill the patient for the balance?

Since the payer already paid the patient, you'll generally need to collect the paid amount directly from the patient rather than rebilling the payer, subject to your office's financial policies and any applicable state or payer rules.

How can I prevent this from happening again?

Make sure a signed assignment of benefits form is on file and submitted with claims, and verify network status and payer payee policies before treatment when possible.
