CPT code 35537 is used for a surgical procedure involving an arterial bypass graft from the aorta to the iliac artery.
CPT code 35537 is used to describe a surgical procedure known as an aortoiliac bypass graft. This procedure involves creating a bypass around blocked or narrowed sections of the aorta and iliac arteries, which are major blood vessels supplying blood to the lower part of the body. The bypass is typically constructed using a graft, which can be made from synthetic material or a section of a vein from the patient's body. This code is specifically used to document and bill for the surgical intervention aimed at restoring adequate blood flow to the lower extremities, thereby alleviating symptoms such as pain and improving overall circulation.
When considering the CPT code 35537 for an aortoiliac artery bypass graft, several modifiers may be applicable depending on the specific circumstances of the procedure. Here is a list of potential modifiers that could be used, along with the reasons for their application:
1. Modifier 22 - Increased Procedural Services: This modifier is used when the work required to perform the procedure is substantially greater than typically required. This could be due to unusual anatomy or other complicating factors.
2. Modifier 51 - Multiple Procedures: If multiple procedures are performed during the same surgical session, this modifier indicates 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 is particularly relevant if the bypass graft is performed in conjunction with other vascular procedures.
4. Modifier 62 - Two Surgeons: When two surgeons are required to perform distinct parts of the procedure, this modifier indicates that both surgeons are involved in the operation.
5. Modifier 66 - Surgical Team: If the procedure requires a surgical team due to its complexity, this modifier is used to reflect the involvement of multiple healthcare professionals.
6. Modifier 76 - Repeat Procedure by Same Physician: This modifier is applicable if the same physician needs to repeat the procedure for the same patient on the same day.
7. Modifier 77 - Repeat Procedure by Another Physician: If a different physician repeats the procedure on the same day, this modifier is used.
8. Modifier 78 - Unplanned Return to the Operating/Procedure Room by the Same Physician Following Initial Procedure for a Related Procedure During the Postoperative Period: This modifier is used if the patient needs to return to the operating room for a related procedure during the postoperative period.
9. Modifier 79 - Unrelated Procedure or Service by the Same Physician During the Postoperative Period: This modifier is used when an unrelated procedure is performed by the same physician during the postoperative period of the initial procedure.
10. Modifier 80 - Assistant Surgeon: If an assistant surgeon is necessary for the procedure, this modifier indicates their involvement.
11. Modifier 81 - Minimum Assistant Surgeon: This modifier is used when an assistant surgeon is required for a minimal portion of the procedure.
12. Modifier 82 - Assistant Surgeon (when qualified resident surgeon not available): This modifier is used when an assistant surgeon is required due to the unavailability of a qualified resident surgeon.
These modifiers help provide additional context and detail about the procedure, ensuring accurate billing and reimbursement. It is important to review the specific circumstances of each case to determine the appropriate modifiers to apply.
CPT code 35537 is subject to reimbursement considerations under Medicare, specifically through the Medicare Physician Fee Schedule (MPFS). The MPFS is a comprehensive listing of fees used to reimburse physicians and other healthcare providers for services rendered to Medicare beneficiaries. Whether CPT code 35537 is reimbursed by Medicare depends on several factors, including its inclusion in the MPFS and any local coverage determinations made by the Medicare Administrative Contractor (MAC) responsible for the geographic area where the service is provided.
Each MAC has the authority to interpret national Medicare policies and establish local coverage determinations (LCDs) that can affect the reimbursement of specific CPT codes. Therefore, to determine if CPT code 35537 is reimbursed by Medicare, healthcare providers should consult the MPFS for the current year and check with their respective MAC for any applicable LCDs or additional guidelines that might influence coverage and reimbursement.
