CPT code 35637 is used for a surgical procedure involving an aortoiliac artery bypass, which helps improve blood flow in the lower body.
CPT code 35637 is used to describe a surgical procedure known as an aortoiliac bypass. This procedure involves creating a bypass around blocked or narrowed sections of the aorta and iliac arteries, which are major blood vessels that supply blood to the lower part of the body, including the legs. The bypass is typically constructed using a graft, which can be made from synthetic material or harvested from the patient's own veins. This procedure is often performed to restore adequate blood flow to the lower extremities in patients with peripheral artery disease (PAD) or other vascular conditions that impede circulation.
For CPT code 35637, which pertains to an aortoiliac bypass procedure, the following modifiers may be applicable:
1. Modifier 22 - Increased Procedural Services: Use this modifier if the procedure required significantly more work than typically required. This could be due to unusual anatomy or complications that arose during the surgery.
2. Modifier 51 - Multiple Procedures: If multiple procedures were performed during the same surgical session, this modifier should be used to indicate that more than one procedure was conducted.
3. Modifier 59 - Distinct Procedural Service: This modifier is used to indicate that a procedure or service was distinct or independent from other services performed on the same day. It may be necessary if the bypass was performed in conjunction with other procedures that are not typically reported together.
4. Modifier 62 - Two Surgeons: If two surgeons were required to perform the procedure due to its complexity, this modifier should be used to indicate the involvement of both surgeons.
5. Modifier 66 - Surgical Team: In cases where the procedure required a surgical team due to its complexity, this modifier should be applied.
6. Modifier 78 - Unplanned Return to the Operating/Procedure Room by the Same Physician Following Initial Procedure for a Related Procedure During the Postoperative Period: If the patient required an unplanned return to the operating room for a related procedure during the postoperative period, this modifier would be appropriate.
7. Modifier 80 - Assistant Surgeon: If an assistant surgeon was necessary for the procedure, this modifier should be used to indicate their involvement.
8. Modifier 81 - Minimum Assistant Surgeon: Use this modifier if the assistant surgeon's involvement was minimal.
9. Modifier 82 - Assistant Surgeon (when qualified resident surgeon not available): This modifier is used when an assistant surgeon is required because a qualified resident surgeon was not available.
These modifiers help provide additional information about the circumstances under which the procedure was performed, ensuring accurate billing and reimbursement. Always verify with the latest coding guidelines and payer-specific requirements, as these can vary.
The CPT code 35637 is subject to reimbursement considerations under Medicare, specifically through the Medicare Physician Fee Schedule (MPFS). The MPFS is a comprehensive listing of fees used by Medicare to reimburse physicians and other healthcare providers for services rendered. Whether CPT code 35637 is reimbursed by Medicare depends on several factors, including its inclusion in the MPFS and the specific guidelines set forth by the Medicare Administrative Contractor (MAC) for the region where the service is provided.
Each MAC is responsible for interpreting national Medicare policies and setting local coverage determinations (LCDs) that can affect reimbursement. Therefore, healthcare providers should consult the MPFS to verify if CPT code 35637 is listed and check with their respective MAC to ensure compliance with any local policies that might impact reimbursement. Additionally, providers should ensure that all documentation and billing practices align with Medicare's requirements to facilitate successful reimbursement for this CPT code.
