The procedure described by CPT® Code 35697 involves the reimplantation of a visceral artery to an infrarenal aortic prosthesis. This surgical intervention is typically performed during a separate open procedure on the aorta, where the physician meticulously dissects the visceral vessel from the surrounding soft tissue to prepare it for reattachment. A critical component of this procedure is the creation of a patch from a button of aortic tissue, which is cut from the origin of the visceral vessel. This patch, often referred to as a Carrel patch, is essential for ensuring a secure and effective reattachment to the aortic prosthesis. The smoothness and patency of the button are carefully examined to confirm its suitability for the procedure. Once the patch is prepared, the site on the aortic prosthesis where the reimplantation will occur is clamped using a side-biting clamp. A corresponding hole is then created in the aortic prosthesis to match the size of the aortic button. The Carrel patch is sutured into this hole, establishing a new connection between the visceral artery and the prosthesis. After the clamps are removed, the anastomosis site is thoroughly checked for any signs of leakage, and additional sutures may be applied as necessary to ensure the integrity of the connection. This procedure is primarily aimed at restoring blood supply to the colon by reimplanting the inferior mesenteric artery into the infrarenal aortic prosthesis, although it can also be performed on other visceral arteries. Each instance of visceral artery reimplantation is reported separately using the code 35697.

The procedure described by CPT® Code 35697 is indicated for the re-establishment of blood supply to the colon, primarily through the reimplantation of the inferior mesenteric artery into the infrarenal aortic prosthesis. This procedure may also be indicated for other visceral arteries that require reattachment to ensure adequate blood flow to the corresponding organs or tissues.
The procedure for reimplantation of a visceral artery to the infrarenal aortic prosthesis involves several critical steps that ensure successful attachment and restoration of blood flow.
Post-procedure care following the reimplantation of a visceral artery to the infrarenal aortic prosthesis typically involves monitoring the patient for any complications related to the surgery. This includes checking for signs of leakage at the anastomosis site and ensuring that blood flow is adequately restored to the affected areas. Patients may require follow-up imaging studies to assess the success of the reimplantation and to monitor for any potential issues. Additionally, standard post-operative care protocols should be followed to promote healing and recovery.

| 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.) | 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). | 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 | LT | Left side (used to identify procedures performed on the left side of the body) | RT | Right side (used to identify procedures performed on the right side of the body) | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service |
