Supportive documentation evidencing the condition and treatment must be documented in the medical record and be available to the Contractor upon request.
ICD-10-CM diagnosis codes supporting the medical necessity of the service must be submitted with each claim.
High-utilization or repeat testing should include clinical justification in the record (for example, repeat testing due to unsatisfactory response to treatment) to support medical necessity.
