The CPT® Code 35612 refers to a surgical procedure known as a bypass graft, specifically a subclavian-subclavian bypass graft, which is performed using materials other than vein. This procedure is indicated for patients who have a diseased or obstructed proximal subclavian artery, necessitating the creation of a bypass to restore adequate blood flow. The bypass graft serves to reroute blood around the affected area, thereby addressing issues related to the contralateral (opposite) subclavian artery. The surgical approach involves making an incision at the base of the neck, just above the clavicle, to expose the first subclavian artery. A similar incision is made on the opposite side to access the second subclavian artery. A tunnel is then created across the chest to facilitate the placement of a synthetic graft, which is carefully selected and prepared for the procedure. The graft is sutured to both subclavian arteries, ensuring that blood flow can be restored effectively. The procedure is monitored for patency using Doppler ultrasound, and distal pulses are evaluated to confirm successful blood flow through the newly established bypass graft.

The procedure described by CPT® Code 35612 is indicated for the following conditions:
The surgical procedure for a subclavian-subclavian bypass graft involves several critical steps:
After the completion of the subclavian-subclavian bypass graft procedure, patients are typically monitored for any signs of complications. Expected recovery includes observation of the surgical site for proper healing and assessment of blood flow through the graft. Follow-up appointments may be scheduled to evaluate the success of the bypass and to ensure that there are no issues with patency. 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). | 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) |
