Denial Code OA 136 - Fix Prior Payer Rule Issues
CARC 136 means the claim wasn't processed because it didn't adhere to the coverage rules set by a prior payer. The denial indicates that the current payer identified an issue related to coordination of benefits or similar requirements.
Who Pays: Group Code Liability
With group code OA, the provider cannot bill the patient for the amount adjusted by CARC 136. The adjustment is considered an other adjustment, not a patient responsibility or contractual write-off.
Why Claims Get Code 136
- The claim was submitted without verifying the primary payer's coordination of benefits requirements.
- The service was rendered without obtaining the necessary prior authorization from the primary payer.
- The provider did not adhere to the primary payer's referral requirements.
- The claim lacks documentation showing compliance with the primary payer's coverage rules.
- A misunderstanding or miscommunication regarding which payer's rules apply.
How to Fix & Resubmit
- Verify which payer's rules were not followed by reviewing the remittance advice and any prior communications.
- Check whether the primary payer's prior authorization or referral requirements were met.
- Gather any missing documentation needed to prove compliance with the prior payer's coverage rules.
- Contact the payer's provider services department to clarify the specific rule not followed, if unclear.
- Submit a corrected claim with the necessary documentation or information, if applicable.
Corrected Claim or Appeal?
A corrected claim is generally the right approach if the issue was due to missing documentation or prior authorization. An appeal may be necessary if you believe the payer's determination is incorrect despite compliance.
Preventing Future 136 Denials
- Always verify the primary payer's coverage rules before submitting claims.
- Ensure that all necessary prior authorizations and referrals are obtained and documented.
- Regularly update coordination of benefits information to prevent misrouting.
- Train billing staff on payer-specific requirements to reduce errors.
