Official Description

Splenoportography, radiological supervision and interpretation

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 75810 refers to splenoportography, which is a specialized radiological examination of the spleen and its associated vascular structures. This procedure involves the use of fluoroscopic guidance to accurately place a sheathed needle into the spleen, allowing for the administration of contrast media. The primary goal of splenoportography is to visualize the splenic veins and assess the flow of contrast as it drains into the portal vein, providing critical information about the vascular anatomy and any potential abnormalities. The process begins with the careful insertion of the needle, followed by verification of its correct positioning through the presence of free blood return and a small test injection of contrast. Once confirmed, a larger volume of contrast media is injected, and the resulting images are captured using cineangiography, a technique that allows for dynamic visualization of the vascular structures. After the imaging is completed, Gelfoam plugs are utilized to tamponade the needle tract, ensuring hemostasis. The procedure concludes with the removal of the sheath, application of a dressing, and a thorough review of the radiographs by the physician, who then provides a detailed written interpretation of the findings. This comprehensive approach ensures that the procedure is performed safely and effectively, yielding valuable diagnostic information for further clinical decision-making.

1. Indications

The indications for performing splenoportography, as described by CPT® Code 75810, typically include the following conditions:

  • Assessment of Splenic Veins This procedure is indicated for evaluating the patency and anatomy of the splenic veins, particularly in cases where there is suspicion of vascular obstruction or abnormalities.
  • Portal Hypertension Evaluation Splenoportography may be performed to investigate portal hypertension, which can lead to complications such as varices or splenomegaly.
  • Trauma Assessment In cases of splenic trauma, this procedure can help determine the extent of injury and guide further management.
  • Preoperative Planning It may be indicated for preoperative assessment in patients undergoing splenic surgery or procedures involving the portal venous system.

2. Procedure

The procedure for splenoportography involves several critical steps to ensure accurate imaging and patient safety:

  • Step 1: Needle Insertion The physician begins by placing a sheathed needle into the spleen under fluoroscopic guidance. This step is crucial as it allows for real-time visualization of the needle's trajectory, ensuring precise placement within the splenic tissue.
  • Step 2: Verification of Sheath Positioning After the needle is inserted, the physician removes the needle while verifying the correct positioning of the sheath. This is confirmed by observing free blood return and administering a small test amount of contrast media, which helps ensure that the sheath is properly located within the splenic vasculature.
  • Step 3: Contrast Injection Following the successful verification, a larger volume of contrast media is injected into the spleen. This contrast is essential for visualizing the splenic veins and assessing the flow of blood as it drains into the portal vein. The injection is recorded using cineangiography, which captures dynamic images of the vascular structures.
  • Step 4: Tamponade of Needle Tract To prevent bleeding, Gelfoam plugs are inserted through the sheath to tamponade the entire needle tract. This step is vital for ensuring hemostasis and minimizing the risk of complications.
  • Step 5: Sheath Removal and Dressing Application Once the Gelfoam plugs are in place, the sheath is carefully removed, and a dressing is applied to the insertion site to protect it and promote healing.
  • Step 6: Radiograph Review Finally, the physician reviews the radiographs obtained during the procedure. A detailed written interpretation of the results is provided, summarizing the findings and any relevant observations regarding the splenic and portal venous anatomy.

3. Post-Procedure

After the completion of splenoportography, patients are typically monitored for any immediate complications, such as bleeding or infection at the insertion site. The application of a dressing helps protect the area and promote healing. Patients may be advised to avoid strenuous activities for a short period to allow for proper recovery. Follow-up appointments may be scheduled to discuss the results of the procedure and any further management based on the findings. It is essential for the physician to provide clear post-procedure instructions to ensure patient safety and optimal recovery.

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.
