Official Description

Venography, caval, inferior, with serialography, radiological supervision and interpretation

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 75825 refers to a specialized imaging procedure known as venography, specifically targeting the inferior vena cava. This procedure involves the use of radiological techniques to visualize the veins and assess blood flow. During the venography, a physician administers a contrast medium through an injection into the inferior or superior vena cava or another blood vessel, such as the femoral vein. This contrast agent enhances the visibility of the vascular structures on the radiographs. The procedure is conducted under the supervision of a physician who is responsible for the radiological interpretation of the images obtained. In some cases, serialography may be included, which entails capturing a series of radiographs at specific time intervals to observe the dynamics of blood flow. The physician meticulously reviews the resulting images and provides a comprehensive written interpretation, which is crucial for diagnosing potential vascular issues. It is important to note that CPT® Code 75825 is specifically designated for the inferior vena cava, while CPT® Code 75827 is used for venography of the superior vena cava.

1. Indications

The venography procedure indicated by CPT® Code 75825 is typically performed for various clinical reasons related to the inferior vena cava. The following conditions may warrant this procedure:

  • Assessment of Venous Obstruction This procedure is utilized to evaluate potential blockages or obstructions in the inferior vena cava that may impede normal blood flow.
  • Investigation of Thrombosis Venography is often indicated for diagnosing thrombosis, where blood clots may form within the inferior vena cava, leading to serious complications.
  • Evaluation of Vascular Malformations The procedure can help identify congenital or acquired vascular malformations that may affect the inferior vena cava.
  • Preoperative Planning Venography may be performed as part of the preoperative assessment for surgical interventions involving the inferior vena cava.

2. Procedure

The venography procedure as described by CPT® Code 75825 involves several critical steps to ensure accurate imaging and interpretation. The following procedural steps are typically followed:

  • Step 1: Patient Preparation The patient is positioned appropriately, and the area where the injection will occur is cleaned and sterilized to minimize the risk of infection. The physician may also explain the procedure to the patient to ensure understanding and cooperation.
  • Step 2: Injection of Contrast Media A contrast medium is injected into the inferior vena cava or another blood vessel, such as the femoral vein. This contrast agent is essential for enhancing the visibility of the vascular structures during imaging.
  • Step 3: Radiographic Imaging Following the injection, a series of radiographs are obtained. If serialography is performed, these images are captured at timed intervals using a high-speed camera to observe the flow of blood through the inferior vena cava.
  • Step 4: Radiological Supervision Throughout the procedure, the physician supervises the radiological component, ensuring that the imaging is conducted correctly and that the quality of the images is adequate for interpretation.
  • Step 5: Interpretation of Results After the imaging is complete, the physician reviews the radiographs, analyzes the flow of blood, and provides a detailed written interpretation of the findings, which is crucial for further clinical decision-making.

3. Post-Procedure

After the completion of the venography procedure, patients may be monitored for any immediate adverse reactions to the contrast media. It is essential to observe the injection site for signs of swelling, redness, or discomfort. Patients are typically advised to hydrate adequately to help flush the contrast material from their system. Follow-up appointments may be scheduled to discuss the results of the venography and any further diagnostic or therapeutic steps that may be necessary based on the findings. Additionally, patients should be informed about any specific symptoms to watch for that may require immediate medical attention.

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.
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.
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
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).
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
XE Separate encounter, a service that is distinct because it occurred during a separate encounter
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
