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.
