The medical record must support the selected ICD-10-CM code(s) and the submitted CPT/HCPCS code must accurately describe the service performed.

The medical record must document the ordering provider's assessment related to the patient's complaint prompting external ocular photography, including relevant medical history and physical exam findings supporting medical necessity.
