A face-to-face encounter and a Written Order Prior to Delivery (WOPD) are required for specified HCPCS codes under Final Rule 1713 and must be obtained prior to delivery per the LCD-related Standard Documentation Requirements (Article A55426).
The diagnosis code that justifies the need for the HFCWO item must be included on the claim.
The beneficiary's medical record must describe the underlying medical condition(s) causing accumulation of pulmonary secretions, prior and current treatment interventions (e.g., chest physiotherapy, postural drainage, medications, mechanical modalities such as in-exsufflation devices), and the effectiveness of those treatments; this information must be available upon request.
Suppliers must append modifier KX to HFCWO codes only when all LCD Coverage Indications/Limitations/Medical Necessity criteria are met; if not met, suppliers must append GA (if a valid ABN was obtained) or GZ (if no valid ABN was obtained); claim lines without KX, GA, or GZ will be rejected as missing information.

High Frequency Chest Wall Oscillation (HFCWO) devices (HCPCS E0483) are covered under the Durable Medical Equipment benefit when the device is reasonable and necessary for the beneficiary per the related Local Coverage Determination (LCD) and all applicable Medicare statutory and regulatory requirements are met.
Mechanical in-exsufflation devices are covered under the Durable Medical Equipment (DME) benefit when the beneficiary meets the reasonable and necessary (R&N) requirements specified in the related Local Coverage Determination (LCD).
Replacement reimbursement for HCPCS A7020 is allowed only if the beneficiary owns or is purchasing the mechanical in-exsufflation device and the claim includes the diagnosis code that justifies medical need.
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.
