Official Description

Direct repair of aneurysm, pseudoaneurysm, or excision (partial or total) and graft insertion, with or without patch graft; for aneurysm, pseudoaneurysm, and associated occlusive disease, splenic artery

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 35111 involves the surgical intervention for the repair of a splenic artery aneurysm or pseudoaneurysm, which may also include associated occlusive disease. An aneurysm is characterized by an abnormal enlargement or dilation of an artery, which can arise from various causes such as arteriosclerosis, mechanical obstruction, or malposition of the artery. Less frequently, conditions like syphilis, tuberculosis, or fibromuscular dysplasia may contribute to the formation of an aneurysm. In contrast, a pseudoaneurysm is a hematoma that forms in communication with the artery wall but does not involve all three layers of the arterial wall, typically resulting from trauma or complications from medical procedures. The splenic artery, which is the focus of this procedure, originates from the celiac trunk and is responsible for supplying blood to the spleen. Surgical repair may involve direct repair or excision of the aneurysm, along with the insertion of a graft, which can be either autogenous, such as a saphenous vein graft, or synthetic. This procedure is performed in a nonemergent, elective setting, distinguishing it from similar procedures that may be conducted in emergency situations, such as the repair of a ruptured splenic aneurysm.

1. Indications

The procedure described by CPT® Code 35111 is indicated for the following conditions:

  • Aneurysm of the splenic artery - This condition involves an abnormal enlargement of the splenic artery, which may require surgical intervention to prevent rupture or complications.
  • Pseudoaneurysm of the splenic artery - This condition occurs when there is a hematoma that communicates with the artery wall, often resulting from trauma or procedural complications, necessitating repair to restore normal blood flow.
  • Associated occlusive disease - This refers to any additional vascular conditions that may be present alongside the aneurysm or pseudoaneurysm, which could impact blood flow and require surgical correction.

2. Procedure

The surgical procedure for CPT® Code 35111 involves several critical steps to ensure the successful repair of the splenic artery aneurysm or pseudoaneurysm:

  • Preparation and Incision - The patient is positioned appropriately, and the lower leg is prepped if a saphenous vein graft is to be harvested. A midline abdominal, transverse, or retroperitoneal flank incision is made to access the splenic artery.
  • Accessing the Splenic Artery - The overlying soft tissues are carefully divided to expose the splenic artery. The duodenum is dissected off the aorta to provide clear access, and the aorta is exposed for further manipulation.
  • Establishing Control - Proximal control is established above the level of the celiac arteries, and distal control is secured above the iliac arteries. This is crucial for managing blood flow during the repair process.
  • Mobilizing the Aorta - Supraceliac aortic control is achieved by dividing ligaments to the left lateral segment of the liver and retracting this portion of the liver. The diaphragm's fibromuscular bands (crura) are separated to facilitate the mobilization of the aorta.
  • Clamping and Repairing the Aneurysm - After administering anticoagulants, the iliac arteries and proximal aorta are clamped. The aneurysm sac in the splenic artery is then opened longitudinally, and any thrombus is removed. The splenic artery is repaired using either an autogenous (saphenous vein) or synthetic patch or tube graft.
  • Closure - If a tube graft is placed, the aneurysm sac is closed over the graft. Once the clamps are released, blood flow is re-established. The retroperitoneum is repaired, and the abdomen is closed to complete the procedure.

3. Post-Procedure

Post-procedure care following the repair of a splenic artery aneurysm or pseudoaneurysm includes monitoring for any signs of complications, such as bleeding or infection. Patients are typically observed in a recovery area until stable. Pain management is provided as needed, and the surgical site is monitored for proper healing. Follow-up appointments are essential to assess the success of the repair and to ensure that there are no further vascular issues. Patients may also receive instructions regarding activity restrictions and signs of potential complications that should prompt immediate medical attention.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m 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).
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
