Summary & Overview
CPT 75885: Percutaneous Transhepatic Portography with Hemodynamic Evaluation
CPT code 75885 describes the imaging supervision and interpretation for percutaneous transhepatic portography, a specialized interventional radiology procedure that visualizes the portal venous system and includes hemodynamic evaluation. This code matters nationally because it captures services used to diagnose and evaluate portal vein patency and portal hypertension — conditions with significant implications for patient management and resource use. Payors commonly covering services of this type include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context for percutaneous transhepatic portography, the typical sites of service, and what the code represents administratively. The publication also summarizes expected billing elements and common modifiers, outlines the clinical rationale for using the procedure, and highlights where stakeholders should look for policy or reimbursement updates. Data not available in the input is noted where applicable. This report is written for a national audience of providers, coders, and policy analysts seeking a clear reference on CPT code 75885 and its clinical and billing context.
Billing Code Overview
CPT code 75885 describes imaging supervision and interpretation for percutaneous transhepatic portography. The procedure involves injection of contrast medium into the portal venous system via a needle or catheter placed in the liver to visualize portal vein anatomy and assess patency.
Service type: Diagnostic imaging with hemodynamic evaluation, including measurement of portal system blood flow and pressures.
Typical site of service: Hospital outpatient interventional radiology or inpatient interventional radiology suite.
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with chronic liver disease and suspected portal vein thrombosis presents with worsening abdominal pain, ascites, and abnormal liver function tests. Noninvasive imaging (Doppler ultrasound, CT or MRI) is inconclusive for portal venous patency and portal hypertension assessment. The interventional radiology team schedules a percutaneous transhepatic portography to visualize the portal venous system and perform hemodynamic measurements.
The clinical workflow: the patient is consented and prepped in an IR suite or hybrid operating room. Conscious sedation or general anesthesia is administered per patient factors and anesthesiology evaluation. Under ultrasound and fluoroscopic guidance, an interventional radiologist accesses a peripheral intrahepatic portal vein branch with a needle or small-gauge catheter through a transhepatic approach. Contrast medium is injected while fluoroscopic images are obtained to assess portal vein anatomy, detect thrombosis, stenosis, or collaterals, and to evaluate portal venous pressure and gradient (hemodynamic evaluation). Images are interpreted by the performing physician and a procedural report documents findings, pressures, volumes of contrast, complications, and recommended next steps. Typical site of service is an interventional radiology suite, catheterization laboratory, or hybrid OR. Indications include evaluation of portal vein patency, pre-transplant assessment, portal hypertension workup, and planning for portal vein interventions such as transjugular intrahepatic portosystemic shunt (TIPS) or portal vein recanalization.
