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.
- Occupational therapy is covered for patients with migraine (G43.xx) who require training to reduce pain during basic and instrumental activities of daily living, typically completed in 3–4 sessions.
- Electrical stimulation (attended CPT 97032 or unattended HCPCS G0283) may be covered as part of a therapy plan of care to improve function when the nerve supply to the muscle is intact and atrophy is due to non-neurological disuse (e.g., post-casting, splinting, soft-tissue scarring).
- Wheelchair management training (CPT 97542) is covered for patient and/or caregiver training in transfers and propulsion when documentation ties the training to attainable functional goals.
- Therapeutic exercise (CPT 97110) is covered when used to address impairments of exercise tolerance due to cardiopulmonary impairments.
