Common Pitfalls and How to Streamline Primary vs. Secondary Billing
You’ve learned how to determine primary vs. secondary insurance but even the best processes can go off track without the right systems in place.
In the final post of our “Getting COB Right” series, we’ll highlight the most common mistakes practices make when managing patients with multiple insurances and the technology and tools that help eliminate them.
Common COB Mistakes to Avoid
Assuming Medicare is Always Primary
Medicare is not primary if the patient:
- Is actively employed and covered by a group plan (20+ employees)
- Is disabled but has coverage through a large employer plan
- Is treated for a work-related injury (covered by workers’ comp)
Billing Medicaid First
Medicaid is always the payer of last resort. If any other coverage exists commercial, employer, or Medicare those must be billed first.
Forgetting to Verify Effective Dates
A card alone isn’t proof of active coverage. Always confirm start and end dates in payer portals before submitting claims.
Ignoring Coverage Changes
Patients frequently forget to mention insurance changes during open enrollment or after life events (marriage, divorce, retirement). Always ask at check-in:
- “Have there been any insurance changes since your last visit?”
- “Are you or your spouse still employed under the same plan?”
Not Updating COB Annually
COB can change mid-year. Review and update at least once annually or anytime a patient reports coverage changes.
Tools That Simplify COB Verification
Using modern digital tools can drastically reduce COB errors and improve claim turnaround times.
Pro Tip: Document COB verification details inside your EHR every time you confirm payer order. This creates a paper trail if claims are ever questioned.
Conclusion
Mastering primary vs. secondary insurance is about more than just billing order it’s about building a reliable, repeatable process that protects your revenue and keeps patients from surprise bills.
By combining smart verification practices with the right technology, your team can stay compliant, get paid faster, and deliver a better patient experience.
