2025 CPT code 75820
Venography, extremity, unilateral, radiological supervision and interpretation.
Modifiers 26 (professional component), TC (technical component), 52 (reduced services), and other relevant modifiers can be used depending on the specific circumstances.
Medical necessity for 75820 must be supported by documentation demonstrating the clinical indication for the venography, such as symptoms or suspected conditions related to the veins in the extremity being examined. The documentation should also explain why the venogram is necessary for diagnosis or treatment planning.
The physician's responsibility includes supervising and interpreting the venography procedure. They may also perform the access puncture and catheter placement for contrast injection.
In simple words: The doctor looks at X-ray images of the veins in one arm or leg after a special dye is injected to make them visible. This helps the doctor find problems with blood flow in the veins.
This code represents the physician's supervision and interpretation of a venography procedure on one extremity (arm or leg). It includes the injection of contrast material and imaging of the veins using X-ray technology. The procedure helps diagnose conditions related to the veins, such as blockages or abnormalities.
Example 1: A patient presents with swelling and pain in their left leg, possibly due to a deep vein thrombosis (DVT). A unilateral venogram of the left leg is performed to assess the veins for clots., A patient with a history of upper extremity venous access for dialysis experiences arm swelling and pain. A venogram of the affected arm is performed to evaluate for venous stenosis or occlusion., A patient is scheduled for varicose vein surgery. A preoperative venogram of the affected leg is performed to map the venous anatomy and plan the surgical approach.
Documentation should include details of the patient's symptoms, medical history, the reason for the venogram, the extremity examined, the findings of the imaging study, and the physician's interpretation.
