HCPCS Code A4224: Supplies for Maintenance of Insulin Infusion Catheter, Per Week

HCPCS Code A4224 is defined as "Supplies for maintenance of insulin infusion catheter, per week." This code covers all necessary weekly supplies used with an external insulin infusion pump (E0784) for continuous subcutaneous insulin infusion. Because A4224 directly supports insulin infusion therapy, it is most commonly billed for patients with type 1 or insulin-dependent diabetes.

The HCPCS code for an insulin infusion pump is E0784. It is described as an "External ambulatory infusion pump, insulin." This code is specifically used to represent the actual insulin pump device used for continuous subcutaneous insulin delivery. It falls under the category of durable medical equipment (DME) and infusion pumps and supplies.

Medicare covers HCPCS Code A4224 when Medicare is the primary payer, provided all coverage and documentation requirements are met. Coverage does not depend on prior payment of related claims.
