Summary & Overview
CPT 75891: Hepatic Venography Imaging Supervision and Interpretation
CPT code 75891 designates the imaging supervision and interpretation component of hepatic venography performed after injection of contrast material via a wedged or free hepatic vein catheter, without a hemodynamic assessment. Nationally, this code identifies services tied to diagnostic visualization of hepatic venous anatomy often used in evaluation of liver vascular disorders, portal hypertension workup, or preprocedural planning for hepatology and interventional procedures. Recognition of this code matters for accurate billing, service-line accounting, and clinical documentation where imaging is performed without catheter-based pressure measurements.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical and billing context for CPT code 75891, expected service setting and service type, and guidance on what content is available or missing for deeper reimbursement and coding comparisons. The summary highlights typical use cases, documentation elements implicit to the code description, and where additional data is needed. Data not available in the input includes associated taxonomies, ICD-10 diagnoses, related codes, and payer-specific reimbursement benchmarks.
Billing Code Overview
CPT code 75891 describes imaging supervision and interpretation of hepatic venography performed after injection of contrast material through a wedged or free catheter in the hepatic vein. The procedure visualizes hepatic venous structure; a hemodynamic evaluation is not performed under this code.
-
Service type: Diagnostic imaging supervision and interpretation of hepatic venography
-
Typical site of service: Hospital radiology or interventional radiology suite (inpatient or outpatient settings where vascular catheterization and contrast imaging are performed)

Clinical & Coding Specifications
Clinical Context
A typical patient is a 55-year-old with chronic liver disease and concerns for portal hypertension who is scheduled for hepatic venography. The patient presents to an interventional radiology suite after initial clinical evaluation by hepatology showing unexplained ascites and variceal bleeding risk. Vascular access is obtained (usually via right internal jugular or femoral vein), and a wedged or free catheter is advanced into a hepatic vein. Contrast is injected while fluoroscopic imaging is performed to visualize hepatic venous anatomy, patency, and possible thrombus or arteriovenous shunting. The procedure includes imaging supervision and interpretation without performing a separate hemodynamic pressure measurement. Typical workflow includes pre-procedure consent and review, vascular access and catheter placement by the proceduralist, contrast injection with live fluoroscopic imaging, documentation of images and interpretation, and post-procedure recovery and discharge instructions. Typical site of service is an outpatient or hospital-based interventional radiology suite; the service type is diagnostic imaging supervision and interpretation of hepatic venography. Emergency scenarios (acute variceal bleeding) may occur but most studies are scheduled as elective diagnostic venography.
