Official Description

Excision of infected graft; extremity

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 35903 involves the excision of an infected vascular graft located in an extremity. A vascular graft is a medical device used to replace or repair damaged blood vessels, and when such a graft becomes infected, it poses significant risks to the patient's health. The excision of the infected graft is a critical surgical intervention aimed at removing the source of infection to prevent further complications. Prior to the excision, a re-vascularization procedure is typically performed, which involves the placement of a new graft. This step is essential to ensure that the affected limb or organ continues to receive adequate blood flow during and after the removal of the infected graft. The surgical process includes careful exposure and dissection of the infected graft from surrounding tissues, clamping of the inflow and outflow arteries to control blood flow, and meticulous debridement of the arterial walls at the anastomosis sites to remove any inflamed tissue. The procedure concludes with the repair of the arterial defect using sutures, ensuring the integrity of the blood vessels is restored. This code is specifically designated for extremity grafts, distinguishing it from similar procedures performed on grafts located in other anatomical regions, such as the neck, thorax, or abdomen.

1. Indications

The excision of an infected vascular graft in the extremity, as described by CPT® Code 35903, is indicated in the following scenarios:

  • Infected Vascular Graft: The primary indication for this procedure is the presence of an infection in a vascular graft located in an extremity, which can lead to serious complications if not addressed.
  • Compromised Blood Flow: The procedure is also indicated when the infected graft compromises blood flow to the affected limb, necessitating intervention to restore adequate perfusion.
  • Surrounding Tissue Inflammation: Inflammation or necrosis of the surrounding tissues due to the infection may also warrant the excision of the graft to prevent further tissue damage.

2. Procedure

The procedure for excising an infected vascular graft in the extremity involves several critical steps:

  • Step 1: Re-vascularization Procedure: Before the excision of the infected graft, a separately reportable re-vascularization procedure is typically performed. This involves the placement of a new graft to ensure that the affected organ or limb receives adequate blood flow during the excision process.
  • Step 2: Exposure of the Infected Graft: The surgeon then exposes the infected graft by carefully dissecting it free from the surrounding tissues. This step is crucial to access the graft without causing additional damage to adjacent structures.
  • Step 3: Clamping of Arteries: Once the graft is exposed, the inflow and outflow arteries are clamped above and below the graft. This clamping is essential to control blood flow and minimize bleeding during the excision.
  • Step 4: Excision of the Graft: The infected graft is then excised from the body. This step requires precision to ensure that the graft is completely removed without leaving any infected tissue behind.
  • Step 5: Debridement of Arterial Walls: After the graft is excised, the inflow and outflow arterial walls at the proximal and distal anastomosis sites are debrided. This involves removing any inflamed or necrotic tissue until healthy, non-inflamed artery is encountered, which is critical for proper healing.
  • Step 6: Repair of Arterial Defect: Finally, the arterial defect created by the excision of the graft is repaired using sutures. This step restores the integrity of the blood vessels and ensures that blood flow can be re-established through the newly placed graft.

3. Post-Procedure

Post-procedure care following the excision of an infected vascular graft in the extremity involves monitoring for signs of infection, ensuring proper healing of the surgical site, and assessing the functionality of the newly placed graft. Patients may require follow-up appointments to evaluate the success of the re-vascularization procedure and to manage any potential complications. Pain management and wound care instructions will also be provided to facilitate recovery. It is essential to monitor the patient for any signs of compromised blood flow to the extremity, as this could indicate issues with the new graft or the healing process.

78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
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).
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.
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
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.
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.
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.
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.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
81 Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number.
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).
