Venography, specifically renal venography, is a specialized radiological procedure aimed at visualizing the renal veins to assess various vascular conditions. This procedure involves the use of a radiopaque contrast medium, which is a substance that enhances the visibility of internal structures during imaging. The process is conducted under radiological supervision, ensuring that the imaging is performed accurately and safely. The primary purpose of renal venography is to diagnose a range of conditions that may affect the renal veins, including blood clots, tumors, retroperitoneal fibrosis, renal agenesis, venous anomalies, and renovascular hypertension. The procedure typically begins with the access of the femoral vein, which is usually approached through the right or left groin using a large bore needle. Following this, a guidewire is inserted through the needle and advanced into the vena cava, leading to the renal veins. A catheter is then placed over the guidewire to the targeted area, allowing for the injection of the contrast medium. As the contrast flows through the renal veins, X-ray images are captured to visualize the anatomy and any potential abnormalities. The procedure concludes with the removal of the catheter, and the findings are documented in a written report, which includes the review and interpretation of the images obtained. This code specifically reports the unilateral selective renal venography procedure, distinguishing it from bilateral procedures, which are coded differently.

Renal venography is performed for several specific indications, primarily to evaluate conditions affecting the renal veins. The following are the explicitly provided indications for this procedure:
The renal venography procedure involves several critical steps to ensure accurate imaging and assessment of the renal veins. The following outlines the procedural steps:
Following the renal venography procedure, patients may be monitored for any immediate complications related to the access site or the use of contrast medium. It is essential to observe for signs of bleeding, infection, or allergic reactions to the contrast material. Patients are typically advised to rest and may be instructed to hydrate adequately to help flush the contrast medium from their system. The results of the venography, including the images obtained and any findings, will be compiled into a written report for review by the referring physician. This report is crucial for determining the next steps in the patient's care and management based on the findings of the procedure.

| 26 | Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number. | 51 | Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d). | 59 | Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25. | GC | This service has been performed in part by a resident under the direction of a teaching physician | LT | Left side (used to identify procedures performed on the left side of the body) | RT | Right side (used to identify procedures performed on the right side of the body) | X4 | Episodic/focused services: for reporting services by clinicians who provide focused care on particular types of treatment limited to a defined period and circumstance; the patient has a problem, acute or chronic, that will be treated with surgery, radiation, or some other type of generally time-limited intervention; reporting clinician service examples include but are not limited to, the orthopedic surgeon performing a knee replacement and seeing the patient through the postoperative period | X5 | Diagnostic services requested by another clinician: for reporting services by a clinician who furnishes care to the patient only as requested by another clinician or subsequent and related services requested by another clinician; this modifier is reported for patient relationships that may not be adequately captured by the above alternative categories; reporting clinician service examples include but are not limited to, the radiologist's interpretation of an imaging study requested by another clinician | XS | Separate structure, a service that is distinct because it was performed on a separate organ/structure | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service |
