HCPCS Level II code S5502 represents a per-diem home infusion therapy service for catheter care and maintenance of an implanted vascular access device, covering administrative, pharmacy professional, care coordination, and supply elements while excluding drugs and nursing visits. Nationally, this code matters because home infusion and vascular access maintenance are central to outpatient delivery of complex therapies, support patient safety, and influence total cost of care for patients with implanted devices. Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will learn how S5502 is defined clinically and operationally, which services are bundled versus billed separately, and typical sites of service and clinical context for use. The publication provides benchmarks and coding context where available, explains common billing practices and exclusions (noting that drugs and nursing visits are coded separately), and highlights policy and coverage considerations that affect authorization and reimbursement workflows. Data not provided in the input (such as payor-specific rates, associated taxonomies, and ICD-10 mappings) are identified as unavailable. This summary is intended to support clinical, billing, and policy stakeholders seeking a concise national overview of S5502 and its role in home infusion care.
