CPT code 96377 covers the preparation and application of an on‑body injector that, upon activation, inserts a subcutaneous cannula and delivers medication in timed increments. This code represents a device‑based administration service distinct from direct clinician-administered injections and is increasingly relevant as wearable automated delivery systems expand for oncology, biologic, and specialty drug therapies. Nationally, clear coding for device preparation and application affects billing consistency, coverage determinations, and care coordination for therapies requiring timed multi‑dose delivery.

Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of what CPT code 96377 represents clinically and operationally, common billing and documentation considerations tied to device‑based, programmed delivery, and typical sites of service where the procedure is provided. The publication also summarizes benchmark themes and recent policy considerations relevant to automated on‑body injectors, helping providers and billing teams understand coding context, payer coverage implications, and areas to monitor for policy updates or payer guidance.
