Summary & Overview
CPT 3502F: Specific Clinical Service
CPT code 3502F denotes a defined clinical service within the Current Procedural Terminology code set; the provided input does not include a descriptive summary. Nationally, CPT codes provide standardized identifiers for clinical procedures and services used across payers and care settings, enabling consistent billing, quality measurement, and claims processing. This code’s precise clinical meaning is not available in the input, but it remains a billable CPT entry whose interpretation affects coding, reimbursement, and reporting practices.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what the code represents (to the extent available), the implications for national billing workflows, and an outline of areas where additional detail is required. The publication highlights typical content readers can expect: benchmark context where available, policy and coverage considerations relevant to major payers, and the clinical context that informs appropriate use of a CPT code. When specific data elements are missing from source input, this summary notes those gaps and signals where further specification is needed for operational or compliance purposes.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult admitted to a hospital or seen in an outpatient vascular access clinic for placement or evaluation of a central venous catheter (e.g., for hemodialysis, long-term antibiotics, total parenteral nutrition, or chemotherapy). The workflow begins with history and indication confirmation, informed consent, review of prior imaging and coagulation status, and site selection (internal jugular, subclavian, or femoral). The procedure is performed by an interventional radiologist, vascular surgeon, or interventional nephrologist in a procedure suite, operating room, or interventional radiology suite with ultrasound and fluoroscopic guidance. Sedation or local anesthesia is administered per institutional protocol. Real-time ultrasound is used for vessel localization and access, followed by guidewire placement and catheter advancement under fluoroscopy. Post-procedure imaging or chest radiograph confirms catheter tip position and rules out complications such as pneumothorax. Documentation includes indication, technique, devices used, catheter type and length, laterality, any complications, and post-procedure instructions. Typical patients include those with end-stage renal disease requiring hemodialysis access, patients needing prolonged central venous therapy, or those with poor peripheral access.
Coding Specifications
| Modifier | Description | When to Use |
