Prior Authorization
No Prior Auth Required
Code is covered without prior authorization (high confidence)
Documentation Required
- All documentation must be maintained in the patient's medical record, be legible, include appropriate patient identification (e.g., full name, dates of service), and be available to the contractor upon request.
- The medical record must identify the physician or non-physician practitioner responsible for and providing the care.
- The submitted medical record must support the selected diagnosis code(s) and the submitted CPT/HCPCS code must accurately describe the service performed.
- For wound-related modalities (G0281, G0329) document wound etiology and duration and prior treatments by physician, non-physician practitioner, nurse, and/or therapist (additional required wound documentation text truncated in source).
Key Coverage Criteria
- Regional or local nerve blocks performed as part of an operative procedure (e.g., adjunct to or sole means of regional/local anesthesia for the procedure) are not affected by this non-coverage policy and may be billed as anesthesia for the operative procedure.
- CPT 97032 (attended/manual electrical stimulation) is covered when delivered with direct 1-on-1 contact by qualified personnel (examples: direct motor point stimulation; FES/NMES when performed with therapeutic exercise, neuromuscular reeducation, or functional activities).
- CPT 97032 may be billed for the application, instruction, and adjustment of a TENS unit or other probe-based stimulation (including determining trigger points) when provided as an attended/manual modality.
- Non-implantable pelvic floor electrical stimulation (97032 for probes; G0283 for electrode-based delivery) is covered for treatment of stress and/or urge urinary incontinence in cognitively intact, motivated patients who have failed a documented 4-week trial of pelvic muscle exercise (PME) training.
- HCPCS G0283 (unattended/supervised electrical stimulation) is covered for non-wound-care indications as part of a therapy plan of care when delivered without constant direct contact after skilled application (examples: TENS, IFC, cyclical muscle stimulation).
- HCPCS G0329 (electromagnetic therapy) is covered for chronic stage III/IV pressure ulcers, arterial ulcers, diabetic ulcers, and venous stasis ulcers that show no measurable signs of healing after 30 days of conventional care as part of a therapy plan of care.
