2025 CPT code 75831
(Active) Effective Date: N/A Revision Date: N/A Diagnostic Radiology - Venography Radiology Feed
Selective venography of a single kidney, including radiological supervision and interpretation.
Modifiers 26 (professional component) and TC (technical component) may be appended as appropriate based on the provider's role and payer guidelines.
Medical necessity is established by the presence of clinical symptoms or findings suggesting a need to evaluate the renal venous system. Examples include suspected renal vein thrombosis, evaluation of renal masses, pre-operative planning for renal surgery, or evaluation of post-biopsy complications.
The radiologist is responsible for the radiological supervision and interpretation of the venography. This includes selecting the appropriate imaging technique, injecting the contrast media, acquiring and reviewing the images, and generating a report with the findings.
In simple words: This code covers an X-ray test of a kidney's veins. A special dye is injected into the vein, and X-rays are taken to check for blood clots or other vein problems. A doctor specializing in interpreting medical images reviews the results.
This CPT code encompasses the radiological supervision and interpretation of a selective venography procedure of one kidney.The procedure involves the selective catheterization of the renal vein(s) to visualize and assess the venous system of a single kidney using contrast media and fluoroscopy. The radiologist interprets the resulting images to diagnose conditions such as renal vein thrombosis or other vascular abnormalities.
Example 1: A patient presents with suspected renal vein thrombosis. A selective renal venogram is performed to confirm the diagnosis and assess the extent of the thrombosis. The radiologist interprets the images and provides a detailed report to the nephrologist., A patient undergoes a renal biopsy. Post-biopsy, a selective renal venogram is performed to assess for bleeding or other complications. The radiologist reviews the venogram and determines if any interventional procedures are necessary., A patient with suspected renal tumor undergoes a preoperative assessment including a selective renal venogram to evaluate the tumor's vascular supply. The radiologist reports their findings to the surgeon to help with surgical planning.
** When performing venography in conjunction with other procedures, careful attention to documentation is needed to ensure correct coding and accurate reimbursement. Consult the latest CPT and NCCI guidelines for specific instructions.
