1. Understand Coordination of Benefits (COB)
✔ COB happens when a patient has more than one insurance plan
✔ Insurance carriers decide who pays first (primary vs. secondary)
✔ Incorrect order of benefits often leads to claim denials
2. Steps to Prevent COB Denials
✔ Always ask patients about additional coverage at each visit
✔ Update both plans with correct coordination details
✔ Use payer portals to confirm primary and secondary status
3. When a COB Denial Occurs
✔ Contact the insurance to verify which plan is primary
✔ Request COB updates and submit necessary forms
✔ Resubmit the claim once payer records are corrected
4. Best Practices for COB Handling
✔ Train front desk to collect dual coverage details upfront
✔ Document insurance conversations in patient notes
✔ Use clearinghouse alerts to flag COB conflicts early
5. Common Challenges & Fixes
| Challenge | Fix |
| Denied due to outdated COB info | Call payer and update records before resubmission |
| Patient unaware of secondary plan | Recheck intake forms and employer insurance |
| COB delays in payment | Follow up with both insurers every 7 days |
| Repeat denials for same patient | Flag account and verify benefits before each visit |
