This diagnosis is not covered — missing/incomplete/invalid diagnosis

What Does This Code Mean?

The diagnosis code submitted is not covered for the billed service, or is missing/invalid.

Common Causes

  • ICD-10 code doesn't match payer coverage policy for the CPT
  • Diagnosis code truncated or invalid for date of service
  • Diagnosis pointer on claim doesn't align with documentation

Recommended Next Steps

  1. Cross-check ICD-10 code validity for the date of service
  2. Confirm the diagnosis supports medical necessity per payer policy
  3. Correct and resubmit as a corrected claim
  4. Query the provider if documentation doesn't support a covered diagnosis
