CPT code 35566 is used for a surgical procedure involving an arterial bypass from the femoral to the anterior or posterior tibial or peroneal artery.
CPT code 35566 is used to describe a surgical procedure known as an "arterial bypass graft" involving the femoral artery and the anterior or posterior tibial or peroneal artery. This procedure is typically performed to restore adequate blood flow to the lower extremities, often in patients with peripheral artery disease (PAD) or other conditions that cause significant arterial blockages. The bypass involves creating a new pathway for blood to flow around a blocked or narrowed artery, using either a vein from the patient's body or a synthetic graft. This code is crucial for accurately documenting the procedure for billing and insurance purposes, ensuring that healthcare providers are reimbursed appropriately for the complex surgical work involved.
For CPT code 35566, which involves arterial bypass grafting from the femoral to the anterior or posterior tibial or peroneal artery, the following modifiers may be applicable:
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 factors such as increased complexity or time.
2. Modifier 51 - Multiple Procedures: If multiple procedures are performed during the same surgical session, this modifier indicates that multiple services were provided.
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 often used to bypass National Correct Coding Initiative (NCCI) edits.
4. Modifier 62 - Two Surgeons: When two surgeons work together as primary surgeons performing distinct parts of a procedure, this modifier is used to indicate the collaborative effort.
5. Modifier 66 - Surgical Team: This modifier is applicable when a complex procedure requires the skills of several physicians, often from different specialties, working together as a team.
6. Modifier 76 - Repeat Procedure or Service by Same Physician or Other Qualified Health Care Professional: Used when the same procedure is repeated by the same provider.
7. Modifier 77 - Repeat Procedure by Another Physician or Other Qualified Health Care Professional: This is used when a procedure is repeated by a different provider.
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 when a patient requires a 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 indicates that a procedure performed during the postoperative period was unrelated to the original procedure.
10. Modifier 80 - Assistant Surgeon: Used when an assistant surgeon is required for the procedure.
11. Modifier 81 - Minimum Assistant Surgeon: This 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): Used when an assistant surgeon is necessary due to the unavailability of a qualified resident.
13. Modifier 99 - Multiple Modifiers: When more than four modifiers are necessary to describe the service, this modifier indicates that multiple modifiers are applicable.
Each modifier serves a specific purpose and should be used in accordance with payer guidelines and the specific circumstances of the procedure. Proper use of modifiers ensures accurate billing and reimbursement.
CPT code 35566 is subject to reimbursement considerations under Medicare, but whether it is reimbursed depends on several factors, including its inclusion in the Medicare Physician Fee Schedule (MPFS) and the policies of the specific Medicare Administrative Contractor (MAC) overseeing the region where the service is provided.
The MPFS is a comprehensive listing of fees used by Medicare to reimburse physicians and other healthcare providers on a fee-for-service basis. Each CPT code listed in the MPFS has an assigned relative value unit (RVU) that determines the reimbursement rate. If CPT code 35566 is included in the MPFS, it will have an associated RVU and reimbursement rate.
However, even if a CPT code is listed in the MPFS, reimbursement can still vary based on local coverage determinations (LCDs) made by the MACs. MACs are private organizations contracted by Medicare to process claims and make coverage decisions in specific geographic areas. They have the authority to establish LCDs that specify which services are covered and under what circumstances.
Therefore, to determine if CPT code 35566 is reimbursed by Medicare, healthcare providers should verify its inclusion in the MPFS and consult the relevant MAC's LCDs for any specific coverage criteria or restrictions. This ensures compliance with both national and regional Medicare policies.
