Documentation Required

All documentation must be maintained in the patient's medical record, legible, include patient identification (e.g., full name, dates of service), and be made available to the contractor upon request.
The documentation must include the legible signature of the physician or non-physician practitioner responsible for and providing the care.
The submitted medical record must support the selected ICD-10-CM code(s), the submitted CPT/HCPCS code must describe the service performed, and the record must clearly document medical necessity, the indication for ordering the test, and a clear diagnostic impression.
If documentation is requested, providers must submit a hard copy of waveforms and/or a complete written report with interpretation sufficient to support that the test was medically reasonable and necessary.
