G90.522 — Complex regional pain syndrome I of left lower limb
ICD-10-CM
Prior Authorization
No Prior Auth Required
Code is covered without prior authorization (high confidence)
Documentation Required
- 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).
- For 97032, document the type of electrical stimulation (specify 'manual' and 'attended'), area(s) treated, and when used for muscle weakness include objective strength ratings and functional deficits; when used for pain include pain rating, pain location, and effect of pain on function.
- For non-implantable pelvic floor stimulation, document that the patient is cognitively intact and motivated, that a documented PME training trial was completed (4 weeks) with no clinically significant improvement, and that the nerve supply to the muscle is intact.
Key Coverage Criteria
- 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.
- HCPCS G0281 (unattended electrical stimulation for wounds) is covered for chronic stage III/IV pressure ulcers, arterial ulcers, diabetic ulcers, and venous stasis ulcers that are not demonstrating measurable signs of healing after 30 days of conventional care as part of a therapy plan of care.
