Summary & Overview
HCPCS A4223: Infusion Supplies for Non‑Pump Cassette or Bag
HCPCS Level II code A4223 is used to report infusion supplies associated with a cassette or bag when no external infusion pump is used. The code represents single‑use materials required to prepare and administer an infusion and is relevant across outpatient infusion centers, home infusion services, and ambulatory clinics where medication delivery occurs without a separate pump device. Nationally, accurate coding of supply items affects claims processing, inventory tracking, and provider reimbursement workflows for infusion therapy.
Key payers in the coverage landscape include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a compact overview of the code’s clinical context and common sites of service, plus national benchmarking themes and policy considerations for coverage and billing of infusion supplies. The publication outlines typical use cases for A4223, common modifiers seen on infusion supply lines, and how payers commonly handle bundling and separate supply charges. It also highlights areas where policy updates or payer-specific rules may affect claims adjudication.
This summary is intended to orient billing staff, ambulatory infusion program managers, and payer relations teams to the role of A4223 in infusion billing and to surface the operational and policy topics that follow in the full publication.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult receiving intravenous medication ordered for infusion without use of an external infusion pump (for example, an IV antibiotic, antiemetic, or chemotherapy admixture delivered as a gravity infusion or with an in-line administration set). The patient presents to an outpatient infusion center, emergency department, clinic procedure room, or inpatient ward. A clinician (registered nurse or infusion-trained licensed practical nurse) prepares the medication bag or cassette at the point of care, assembles the IV administration set and tubing, attaches necessary needleless connectors, spike/port access devices, and sterile syringes as needed, and initiates the infusion. Billing uses A4223 to report the infusion supplies furnished per bag or cassette when no external infusion pump is used. Typical workflow steps: clinician verifies order and allergy list, inspects and primes the administration set, spikes the medication bag/cassette, programs any bedside infusion controller if used (but not an external pump), documents lot numbers and start time, monitors infusion and documents patient tolerance, and disposes of single-use supplies per facility policy. Common settings include ambulatory infusion centers, physician offices, urgent care clinics, emergency departments, and hospital bedside administration when gravity or in-line systems are used.
