Claims must be supported by complete, legible medical records that justify the selected ICD-10-CM and CPT/HCPCS codes, include the treating provider’s order and signature, and retain documentation of results when the performing provider differs from the ordering provider; non-covered services must be billed with the appropriate modifier.
