The procedure described by CPT® Code 37225 involves the revascularization of a unilateral femoral or popliteal artery that has become occluded or narrowed due to conditions such as atherosclerosis. This revascularization can be performed through either an open surgical approach or a percutaneous (minimally invasive) technique. The primary goal of this procedure is to restore blood flow to the affected artery, which is crucial for maintaining proper circulation in the lower extremities. The physician utilizes a combination of techniques, including angioplasty and atherectomy, to achieve this goal. Angioplasty involves the use of a balloon catheter to dilate the narrowed artery, while atherectomy employs a specialized device to remove plaque buildup from the arterial wall. The procedure may also include the placement of a stent to keep the artery open after treatment. The choice of approach—open or percutaneous—depends on the specific circumstances of the patient's condition and the physician's assessment. Overall, this procedure is essential for alleviating symptoms associated with arterial occlusion, improving blood flow, and preventing further complications related to peripheral artery disease.

The procedure described by CPT® Code 37225 is indicated for patients presenting with the following conditions:
The procedure begins with the physician selecting the appropriate access site, typically one of the femoral arteries. If an open approach is chosen, the skin over the access artery is prepped and incised to expose the artery. The artery is then nicked, and a sheath is placed to facilitate access. In a percutaneous approach, the skin is similarly prepped, and a needle is used to puncture the artery, followed by the placement of a sheath. Under radiological supervision, a guidewire is inserted through the sheath and advanced into the occluded femoral or popliteal artery. Roadmapping angiograms are obtained to visualize the artery and the extent of the occlusion. A catheter with a balloon tip is then advanced over the guidewire to the site of the blockage. The balloon is inflated, compressing the plaque against the arterial wall, and may be inflated multiple times to achieve optimal results. Alternatively, atherectomy may be performed, utilizing a specialized balloon catheter equipped with a cutting piston that shaves plaque from the arterial wall. The shaved plaque is collected in the device for removal upon completion of the procedure. After achieving the desired results with either angioplasty or atherectomy, the angioplasty or atherectomy device is exchanged for a guidewire, and an angiography catheter is advanced over the guidewire. The guidewire is then withdrawn, and contrast material is injected to perform a completion angiography, ensuring the artery is patent. If necessary, an intravascular stent is positioned at the lesion site using a stent delivery catheter, deployed, and the delivery catheter is removed. A balloon catheter may be used again to inflate and properly seat the stent. Finally, all catheters are removed, and if an open approach was utilized, the access artery is repaired, and the skin incision is closed. In the case of a percutaneous approach, pressure is applied to the vascular access site, followed by the application of a pressure dressing.
Post-procedure care involves monitoring the patient for any complications, such as bleeding or infection at the access site. If an open approach was used, the physician will ensure that the incision is healing properly. Patients may be advised to rest and avoid strenuous activities for a specified period to promote healing. Follow-up appointments are typically scheduled to assess the success of the procedure and to monitor the patient's recovery and overall vascular health. Additionally, the physician may provide guidelines on lifestyle modifications and medications to support vascular health and prevent future occlusions.
