Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves an adult with difficult peripheral venous access requiring central venous catheter placement for infusion therapy, frequent blood sampling, or hemodynamic monitoring. The patient may present in an inpatient ward, emergency department, or outpatient infusion center. A vascular access team or interventional radiology/critical care clinician evaluates the patient, obtains informed consent, performs site assessment (usually internal jugular, subclavian, or femoral), applies sterile technique and ultrasound guidance, and places a nontunneled central venous catheter. The workflow includes pre-procedure time-out, ultrasound localization of target vein, local anesthesia, venous access via Seldinger technique, catheter advancement and securement, verification of placement (fluoroscopy or chest radiograph), and post-procedure monitoring for complications such as pneumothorax, arterial puncture, bleeding, or catheter-related infection. Documentation includes indication, site, catheter type and size, number of lumens, guidance modality, immediate complications, and post-procedure imaging results.
