Summary & Overview
HCPCS S9145: Insulin Pump Initiation, Initial Use Instruction
HCPCS Level II code S9145 represents initiation and initial instruction for insulin pump therapy without inclusion of the pump itself. This code captures the time-limited education and hands-on training required when a patient begins using an insulin pump — a critical step in diabetes management that supports safe device use and adherence. Nationally, insulin pump initiation impacts outpatient diabetes care pathways, patient education programs, and payer coverage policies for durable medical equipment and associated training.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of what the code represents, the clinical context for insulin pump initiation, typical sites of service, and what to expect from payer coverage policies. The publication also summarizes common billing considerations, benchmarking areas, and where policy updates typically affect billing and coverage decisions.
This summary equips clinicians, billing staff, and policy analysts with a concise understanding of HCPCS Level II code S9145, how it fits into care delivery for patients starting insulin pump therapy, and the major payer audiences relevant to coverage and reimbursement discussions.

Clinical & Coding Specifications
Clinical Context
A 42-year-old patient with type 1 diabetes mellitus transitioning from multiple daily injections to continuous subcutaneous insulin infusion (insulin pump). The patient attends an initial pump initiation visit at an outpatient diabetes clinic or endocrinology practice. The visit includes pump setup, programming basal and bolus rates, demonstrating pump functions (bolus delivery, temporary basal, suspend, alarm management), education on infusion set insertion and rotation, site care, troubleshooting occlusions and alarms, carbohydrate counting review, sick-day guidance, and device documentation. A certified diabetes care and education specialist (CDCES) or endocrinology nurse provides one-on-one instruction, confirms patient return demonstration of key skills, and coordinates follow-up training or device download review. Typical sites of service are outpatient clinic, physician office, or specialized diabetes education center. The clinical workflow often follows: pre-visit chart review and device selection, device setup and initial programming, hands-on education and return demonstration, documentation of training provided, and scheduling of device follow-up and supplies authorization.
