- The diagnosis code(s) reported on the claim must best describe the patient's condition for which the visual fields testing was performed.
- Refer to NCCI and OPPS requirements prior to billing Medicare to ensure coding compliance and to determine any bundling or packaging edits.
Key Coverage Criteria
- Continuous intraoperative neurophysiologic monitoring provided one-on-one in the operating room (CPT 95940) is covered when it supports the covered indications in LCD L35003.
- Report continuous intraoperative neurophysiologic monitoring in the operating room (95940) in addition to monitoring services provided from outside the operating room (G0453); coverage includes interpretation of baseline studies and removal of electrodes at the end of the procedure when supporting the LCD indications.
- Reimbursement may be made for covered intraoperative monitoring when performed at POS 19, POS 21, POS 22, or POS 24.
- Monitored Anesthesia Care (MAC) is medically necessary when the patient has one or more documented diagnoses listed as supporting medical necessity (e.g., F91.9, G97.81, T81.9XXA, T88.8XXA, F79) and the diagnosis is matched to the anesthesia/CPT/HCPCS procedure performed.
- Use G9 anesthesia modifier to indicate need for MAC due to a history of severe or advanced cardiopulmonary disease when the proceduralist determines additional monitoring is required.
