Summary & Overview
HCPCS Level II C9814: Continuous Echogenic Conduction Catheter Set
HCPCS Level II code C9814 designates a continuous anesthesia echogenic conduction catheter set — a complete non-opioid medical device kit for continuous regional anesthesia to manage post-surgical pain under qualifying Medicare non-opioid device provisions. The code matters nationally as it formalizes billing for an emerging class of non-opioid pain-control devices that can affect perioperative analgesia protocols and payer coverage decisions following the 2023 Consolidated Appropriations Act provisions.
Key payers in this context include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what this code represents, typical sites of service, and the clinical service type. The publication outlines expected benchmarks for utilization and coverage pathways, summarizes relevant policy updates tied to non-opioid device coverage, and situates the device in clinical practice for post-surgical regional anesthesia.
This material provides clinicians, coding professionals, and policy analysts with a clear description of the code, national implications for device-based non-opioid pain management, and the types of information to seek from payers when determining coverage and billing workflows.
Billing Code Overview
HCPCS Level II code C9814 describes a continuous anesthesia echogenic conduction catheter set (e.g., sonolong, e-cath), including all components, classified as a non-opioid medical device intended for post-surgical pain relief when it qualifies under section 4135 of the Consolidated Appropriations Act, 2023. The code covers the complete device kit designed to provide continuous regional anesthesia using an echogenic (ultrasound-visible) catheter and associated components.
Service Type: Device for continuous regional anesthesia / post-surgical pain management
Typical Site of Service: Hospital inpatient and outpatient surgical settings, ambulatory surgery centers, and post-anesthesia recovery areas
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient undergoes total knee arthroplasty for end-stage osteoarthritis and requires postoperative non-opioid regional analgesia. In the operating room after induction of general anesthesia, the anesthesiology team places a continuous echogenic peripheral nerve catheter (e.g., adductor canal or femoral catheter using a sonolong/e-cath style continuous anesthesia echogenic conduction catheter set) under ultrasound guidance for prolonged postoperative analgesia. The device is secured and connected to an infusion pump in the post-anesthesia care unit. The catheter is managed by the acute pain service with daily assessments for analgesic effectiveness, site inspection, and troubleshooting (e.g., catheter migration or leak). Removal typically occurs on postoperative day 2–4 in the inpatient setting or during a clinic visit if outpatient. Documentation includes indication for non-opioid device use in accordance with the Consolidated Appropriations Act section 4135, device model/HCPCS C9814, ultrasound guidance, insertion level, catheter depth, infusion regimen, and patient response.
