Summary & Overview
HCPCS S5517: Home Infusion Supplies for Catheter Declotting
HCPCS Level II code S5517 denotes the supplies used in home infusion therapy to restore catheter patency or to declot catheters. This code captures single-encounter supply bundles necessary to re-establish or maintain catheter function, a focused service that supports ongoing infusion care at home and helps avoid emergency department visits or facility-based procedures. Nationally, accurate use of this code affects outpatient infusion billing, care coordination between home infusion providers and payers, and utilization patterns for catheter-related complications.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides a concise briefing on clinical context, common sites of service, and payer coverage considerations. Readers will find benchmarks and patterns of use where available, national policy and coverage highlights, and guidance on documentation elements relevant to claims for home infusion catheter declotting supplies. The summary also outlines typical service scenarios and billing workflows tied to home infusion providers and durable medical equipment or home health partners.

Billing Code Overview
HCPCS Level II code S5517 describes home infusion therapy supplies required for restoration of catheter patency or declotting. The service involves provision of all supplies necessary to restore or maintain catheter function when catheter occlusion or clotting impairs infusion therapy.
Service type: Home infusion therapy – catheter declotting/restoration of catheter patency
Typical site of service: Patient home (home health/home infusion setting)
Data not available in the input for associated taxonomies, ICD-10 diagnoses, and related codes.
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient receiving home infusion therapy for long-term intravenous access (tunneled central venous catheter or implanted port) presents with poor catheter flow consistent with partial or complete catheter occlusion. The patient is homebound and managed by a home infusion nursing team. Nursing assesses catheter patency, documents decreased or absent blood return and difficulty flushing, and contacts the supervising clinician. Under standing orders or physician-directed protocol, the nurse prepares thrombolytic or declotting agents and all supplies needed to restore catheter patency. The intervention includes aseptic preparation of the catheter hub, aspiration of residual blood or clot when safe, instillation of a declotting solution (for example, alteplase or other approved thrombolytic) into the catheter lumen, dwell time per protocol, and post-dwell aspiration/flush to confirm restoration of flow. The nursing visit, medication handling, and supplies used for declotting are provided in the patient’s home. Documentation includes indication for declotting, catheter type/location, pre- and post-procedure assessments, medication name/dose, lot numbers of supplies, patient tolerance, and follow-up instructions. This encounter addresses acute catheter occlusion to maintain vascular access for ongoing infusion therapy and to avoid catheter replacement or clinic-based procedures.
