Vein x-ray spleen/liver
CPT code 75810 covers an X-ray examination of the veins in the spleen and liver area, known as splenic and hepatic venography. This specialized imaging study uses contrast dye to visualize blood flow through these veins and identify blockages, abnormalities, or portal hypertension.

Billing tips
Always bill the surgical injection procedure separately using appropriate CPT codes (36481 for percutaneous portal vein catheterization) as 75810 covers only supervision and interpretation
Impact: Captures additional $150-300 in reimbursement for the injection procedure that would otherwise be lost
Document whether procedure is performed in facility or non-facility setting, though 75810 has identical rates ($46.58) for both settings in 2025
Impact: While rates are equal for this code, proper setting documentation prevents audit issues and ensures correct claim submission
Clearly distinguish 75810 from inferior vena cavography (75825) or hepatic venography alone versus combined splenic/hepatic studies in documentation
Impact: Prevents downcoding to less specific codes or denials for lack of medical necessity documentation
When performed with portal vein catheterization or TIPS procedure, ensure 75810 is not bundled by using modifier 59 if truly distinct diagnostic imaging was performed
Impact: May preserve the full $46.58 reimbursement that could otherwise be denied as bundled or inclusive
Bill modifier 26 in non-facility settings where the hospital owns equipment but physician provides only interpretation
Impact: Ensures accurate component billing and prevents overpayment recovery audits
Verify contrast administration is documented with type, amount, and route as 75810 assumes contrast venography; non-contrast studies require different coding
Impact: Prevents denials for incomplete documentation and supports medical necessity with specific clinical detail
