Common Denials & How to Fix Them
CO-18: Duplicate claim/serviceHigh Frequency
Why This Happens
Claim appears to be a duplicate of a previously processed claim
How to Fix It
Verify whether previous claim was paid. If not, resubmit with corrected claim. If it was paid and this is a separate service, add modifier 76 or 77 and documentation explaining why service was repeated.
CO-96: Non-covered chargesCommon
Why This Happens
Service not covered under patient's specific plan benefits
How to Fix It
Review patient's benefit plan. If service should be covered, submit appeal with plan documents and medical necessity. Patient may be responsible if truly non-covered.
