Coordination of Benefits
We encourage providers to submit Coordination of Benefits (COB) claims electronically. COB claims can be processed more efficiently by directly submitting from:
- A provider who has received a remittance advice from the previous payer (provider-to-payer COB).
- The previous payer (payer-to-payer COB).
Tips for Submitting Coordination of Benefits Claims
In order to submit COB claims, your practice management system, data entry portal or clearinghouse must be able to:
- Create or forward claims in full HIPAA standard format (837) or in a format that contains equivalent information and includes necessary COB fields.
- Include electronic payment information received from the primary payer's HIPAA standard electronic remittance advice (ERA).
- Include electronic payment information by converting the primary payer's paper Explanation of Benefits (EOB) into HIPAA standard coding used in an ERA.
