External Infusion Pumps

External infusion pumps and associated drugs/supplies are covered when use is reasonable and necessary and specific clinical criteria are met for conditions including chronic iron overload (deferoxamine), certain unresectable or non-surgical cancers, intractable cancer pain, diabetes requiring continuous subcutaneous insulin infusion with laboratory and education requirements, various prolonged or rate‑controlled parenteral drug regimens, advanced heart failure inotropes, pulmonary hypertension prostacyclins, and selected immune or neurologic therapies. Coverage requires specified laboratory testing and documentation (e.g., C‑peptide, HbA1c, diabetes education, SWO/WOPD, POD), adherence to coding and supplier licensure rules, and limits on supply quantities, durations (e.g., gallium nitrate ≤5 days), and refill processes.

"External infusion pumps (HCPCS E0779, E0780, E0781, E0791) are covered for administration of deferoxamine for treatment of chronic iron overload."
