CPT® Code 92998

Add-On Code

Percutaneous transluminal pulmonary artery balloon angioplasty; each additional vessel (List separately in addition to code for primary procedure)

The procedure described by CPT® Code 92998 refers to a percutaneous transluminal pulmonary artery balloon angioplasty performed on each additional vessel beyond the primary procedure. This intervention is specifically aimed at treating pulmonary artery stenosis, a condition characterized by the narrowing of the pulmonary arteries, which can lead to reduced blood flow and increased pressure in the heart. The procedure is typically initiated by accessing the femoral artery, where the skin is prepped, and a puncture is made to insert a sheath. A guidewire is then navigated through the vascular system to reach the affected pulmonary artery. Following this, a catheter is introduced, allowing for the injection of contrast material to visualize the stenosis through imaging techniques. The angioplasty involves the use of a balloon catheter, which is strategically placed at the site of narrowing and inflated to dilate the artery. This process may require multiple inflations to achieve optimal results, and in some cases, a larger balloon may be utilized for further dilation. The completion of the procedure is confirmed through additional imaging to ensure that the pulmonary artery has been adequately treated. It is important to note that this code is used in conjunction with the primary procedure code for the treatment of a single pulmonary artery, specifically CPT® Code 92997, indicating that 92998 is reserved for each additional vessel treated during the same session.
