When billing non-covered services/tests report unlisted neurological CPT 95999 and provide a description of the service/test in block 80 (Part A) or box 19 (Part B) or electronic equivalent; failure to include this information will result in Part A claims being returned and Part B claims rejected.
All documentation must be maintained in the patient's medical record, be legible, include patient identification and dates of service, and include the legible signature of the responsible physician or non-physician practitioner.
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 the medical necessity, the indication for ordering the test(s), and a clear diagnostic impression.
