2025 CPT code 75833
(Active) Effective Date: N/A Revision Date: N/A Diagnostic Radiology - Venography Radiology Feed
Selective venography of both kidneys, including radiological supervision and interpretation.
Modifiers 26 (professional component) and TC (technical component) may be appended as appropriate.
Medical necessity is established by documenting the clinical suspicion of renal vein pathology, such as suspected thrombosis or tumor invasion.The venography should be performed based on a documented clinical indication.
The radiologist is responsible for the radiological supervision and interpretation of the procedure. This includes needle insertion and catheter placement under fluoroscopic guidance, contrast injection, image acquisition, and image interpretation to determine the location and extent of any abnormalities.
In simple words: This medical code describes an X-ray test of the veins in both kidneys. A special dye is injected into the veins, and X-rays are taken to see if there are any blood clots. A doctor who specializes in reading X-rays interprets the images.
This CPT code, 75833, reports the radiological supervision and interpretation (RSI) of a bilateral, selective renal venography.This is an invasive diagnostic procedure involving the injection of contrast dye into the renal veins, followed by X-ray imaging to visualize the veins and identify blood clots.The procedure requires selective catheter placement to visualize both the left and right renal veins. The radiologist interprets the resulting images to establish a diagnosis.
Example 1: A patient presents with suspected renal vein thrombosis.A bilateral selective renal venography is performed to confirm the diagnosis and determine the extent of the clot. Code 75833 is reported for the radiological supervision and interpretation., A patient with a history of renal cell carcinoma undergoes a bilateral selective renal venography to assess for tumor thrombus extension into the renal veins prior to surgery. Code 75833 is reported for the radiological supervision and interpretation., A patient with recurrent deep vein thrombosis has a bilateral selective renal venography to evaluate for the presence of renal vein thrombus. Code 75833 is reported for the radiological supervision and interpretation.
* Complete patient history, including indication for the procedure.* Detailed report of the venography procedure, including the approach, catheter placement, contrast injection, and image acquisition techniques.* Radiologic images.* Radiologist's interpretation report, including description of findings and diagnosis.
** This code only covers the radiological supervision and interpretation aspect of the procedure.Separate codes are used for the technical component (if applicable) and any interventional procedures.
