Diagnosis Does Not Support the Billed Service

The claim diagnosis may be invalid, incorrectly sequenced, disconnected from the service line, or insufficient to show coverage under the applicable policy.

First checks

  1. 1Compare submitted diagnosis and pointers with the record.
  2. 2Check ICD-10 effective date and official conventions.
  3. 3Read applicable NCD, LCD, article, or payer medical policy.

Resolution path

  1. 01Correct a true coding or pointer error from existing documentation.
  2. 02Do not add an unsupported diagnosis.
  3. 03Appeal when the original record and policy support the service.
  4. 04Request clinician clarification only under compliant documentation rules.

Evidence packet

  • Contemporaneous assessment and plan
  • Diagnostic results
  • ICD-10 guidance
  • Coverage criteria crosswalk

Prevent the next denial

Code diagnoses from the complete record, use correct sequencing and pointers, and verify policy criteria without selecting diagnoses solely to obtain payment.
