The procedure described by CPT® Code 33335 involves the insertion of a graft into the aorta or great vessels, utilizing cardiopulmonary bypass. This surgical intervention is typically indicated in cases of injury to the aorta or great vessels, which may arise from either blunt or penetrating trauma. Such injuries can lead to severe complications, including transection, rupture, tear, or laceration of these critical blood vessels. The use of a synthetic graft is essential for repairing these injuries, as it provides structural support and restores blood flow. The procedure can be performed using two techniques: one that does not require cardiopulmonary bypass, known as the clamp and sew technique (CPT® Code 33330), and the one that does, which is the focus of this code. During the operation, a thoracotomy is performed to access the injured vessels, and careful dissection is carried out to expose the aorta and surrounding structures. The surgical team must take meticulous steps to control bleeding and ensure the integrity of the repair, which involves creating anastomoses between the graft and the aorta or great vessels. This complex procedure is critical for managing life-threatening vascular injuries and restoring hemodynamic stability in affected patients.

The procedure associated with CPT® Code 33335 is indicated for the following conditions:
The procedure for CPT® Code 33335 involves several critical steps to ensure successful graft insertion and repair of the aorta or great vessels:
After the completion of the graft insertion procedure, patients typically require close monitoring in a postoperative setting. The expected recovery may involve managing pain, monitoring for any signs of complications such as bleeding or infection, and ensuring proper function of the graft. Chest tubes, if placed, will be monitored for drainage and may be removed once the output is within acceptable limits. The surgical team will provide specific instructions regarding activity restrictions and follow-up appointments to assess the healing process and the integrity of the graft.

| 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). | 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. | 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.) | 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). | AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | GC | This service has been performed in part by a resident under the direction of a teaching physician |
