Documentation Required

See appendix for additional details on documentation requirements (policy references an appendix)
All medical necessity criteria must be clearly documented in the member's medical record and made available upon request.

Billing rule: For continuous intraoperative neurophysiology monitoring in the operating room with one-on-one monitoring requiring personal attendance, increments of less than 8 minutes should not be billed.

Coverage is contingent on 'selection criteria are met' for each modality (EMG, SSEP, BAER) — the policy repeatedly requires that selection criteria be met for coverage (the specific selection criteria are referenced but not detailed in this text chunk).

No explicit detailed documentation checklist (e.g., required operative/progress notes, test results, or preauthorization items) is provided in this extracted text; however, coverage statements reference specific ICD-10 diagnosis codes and CPT/HCPCS procedure codes which must be present to support medical necessity.
