The following items are identified as not covered / not medically necessary under this policy, with the rationale summarized from the source guidance: Non‑pneumatic compression devices (HCPCS E0678–E0681 and related codes) are not medically necessary because there is insufficient clinical evidence to support their safety and effectiveness compared with standard pneumatic compression devices (source: policy statement on compression therapy and associated code listing).
Cold pad pumps (HCPCS E0236) for postoperative management are listed as not medically necessary; the policy states research does not indicate improved outcomes in pain or edema management compared with conservative measures, cold therapy alone, or standard compression therapy.
Ultrasonic nebulizers (HCPCS E0575) are specified as not medically necessary because they provide no clinical advantage over a small‑volume nebulizer and compressor (E0574), per the policy's respiratory equipment section.
Intrapulmonary percussive ventilation (IPV) devices (e.g., Volara, Percussionaire; HCPCS E1399 when used for IPV) are considered not medically necessary because current evidence does not support their effectiveness.
The wheelchair‑mounted assistive robotic arm (JACO) is classified as not medically necessary due to insufficient clinical evidence demonstrating improved safety or health outcomes compared with alternative technologies (the policy references JACO and associated evidence summaries).
Additionally, the policy flags certain deluxe, aesthetic, or convenience upgrades for DME as not reasonable and therefore not covered when they are beyond medically necessary basic equipment (policy general reasonableness rules and enclosed bed upgrade examples).
