Summary & Overview
HCPCS C9759: Transcatheter Intraoperative Vessel Microinfusion Therapy
HCPCS Level II code C9759 denotes transcatheter intraoperative blood vessel microinfusion therapy, encompassing intraluminal, vascular wall, and/or perivascular delivery during surgery and including radiological supervision and interpretation when provided. This code captures a specialized intraoperative intervention used in vascular and endovascular procedures to deliver therapeutic agents directly to vessel structures.
Nationally, use of HCPCS Level II code C9759 matters for hospitals, ambulatory surgical centers, and radiology teams because it affects intraoperative coding, billing for image-guided interventions, and reporting of advanced vascular therapies. Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise overview of the clinical context for intraoperative microinfusion, typical site-of-service considerations, and how this code is positioned within procedural and imaging billing. The publication outlines common modifiers associated with intraoperative and radiology services, payer coverage patterns, and benchmarking items relevant to revenue cycle and clinical coding teams. Where input fields are not provided, the summary notes that specific data elements are not available in the input. The content is intended for national audiences including coding professionals, clinical leaders, and reimbursement analysts seeking clarity on the code’s clinical scope and billing implications.
Billing Code Overview
HCPCS Level II code C9759 describes transcatheter intraoperative blood vessel microinfusion(s) therapy, for any vessel, and includes radiological supervision and interpretation when performed. The procedure involves targeted microinfusion into the vessel lumen, vascular wall, and/or perivascular space during an intraoperative setting.
-
Service type: Intraoperative transcatheter microinfusion therapy
-
Typical site of service: Operating room or procedural suite where transcatheter vascular interventions and intraoperative imaging are performed
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with refractory focal hepatic metastases from colorectal cancer is taken to the angiography suite during a scheduled transcatheter procedure. Under conscious sedation or general anesthesia, the interventional radiology team gains femoral or radial arterial access and advances microcatheters into segmental hepatic arteries supplying the tumor. Intraoperative microinfusion therapy is delivered intraluminally or via the vascular wall/perivascular space (e.g., chemotherapeutic agent, embolic-delivered drug, or localized biologic agent) with live fluoroscopic guidance. Radiological supervision and interpretation are provided throughout, including angiography before and after infusion to confirm catheter position, vessel patency, and treatment distribution. Hemostasis is achieved at the access site and the patient is monitored in post-anesthesia care prior to discharge or transfer for inpatient observation if indicated.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased Procedural Services | When the work required to perform the microinfusion substantially exceeds the usual service due to complexity, lengthy time, or technical difficulty. |
23 | Unusual Anesthesia |
