Key Coverage Criteria

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.
Range of motion testing (CPT 95851) may be used for extremity ROM when every joint of the extremity is tested and documentation explains why such comprehensive assessment was warranted.
Occupational therapists may recertify home health patients under a plan of care if services meet CMS occupational therapy definitions and the patient's home health eligibility is established by prior need for skilled nursing (not solely venipuncture), speech-language pathology, or physical therapy in the current or prior certification period.
