2025 CPT code 92944
(unknown) Effective Date: N/A Medicine - Cardiovascular Feed
Percutaneous transluminal revascularization of chronic total occlusion, each additional coronary artery, branch, or bypass graft.
Modifiers may be applicable in certain situations, such as reduced services (modifier 52) or staged procedures (modifier 58). Refer to CPT guidelines for proper modifier usage.
Medical necessity for this code requires documentation supporting the diagnosis of chronic total occlusion and the need for percutaneous revascularization in each of the additional vessels treated.The medical record should show that the additional interventions were necessary to restore blood flow and improve the patient's condition.
At the same session as a percutaneous transluminal revascularization of chronic total occlusion for a single coronary artery, branch, or graft, the provider gains access to an additional coronary artery, branch, or graft with chronic total occlusion. When the patient is appropriately prepped and anesthetized, the provider makes an incision into the brachial or femoral artery and inserts a guide wire through it. He then inserts a guide catheter over the guide wire, moving it through the vascular system until he can position the catheter at the opening to the coronary artery. The provider injects a dye and takes fluoroscopic images to examine the blood flow and placement of catheter into the artery. Then he advances a catheter with a burr or other blade into the coronary vessel to destroy the material blocking the artery. At the same session, he may also insert a balloon tipped catheter to the coronary occlusion. He may also insert a balloon mounted catheter with a stent to the occluded site. The balloon expands and fits the stent on the wall of the artery. The provider may also perform an angioplasty, which is where he widens a vessel to open it. The provider finally removes all the equipment, achieves hemostasis, and closes the wound in layers.
In simple words: This add-on procedure is for restoring blood flow in additional blocked heart arteries during the same session as the main procedure (92924, 92928, 92933, 92937, 92941, or 92943). It involves similar techniques like inserting a stent, removing plaque, or widening the artery.
Percutaneous transluminal revascularization of chronic total occlusion, coronary artery, coronary artery branch, or coronary artery bypass graft, any combination of intracoronary stent, atherectomy and angioplasty; each additional coronary artery, coronary artery branch, or bypass graft (List separately in addition to code for primary procedure)
Example 1: A patient presents with chronic total occlusion in two coronary arteries. During the same session, the physician performs the primary procedure (e.g., 92943) on one artery and then uses 92944 to report the revascularization of the second artery., A patient has chronic total occlusion in a coronary artery and a bypass graft. In a single session, the provider treats the native coronary artery (e.g., using 92937) and then uses 92944 to report the intervention on the bypass graft., A patient has chronic total occlusions in three coronary artery branches. The physician performs the primary procedure on one branch (e.g., 92924) and uses 92944 twice to report the treatment of the other two branches during the same session.
Documentation should include details of the primary procedure, the additional vessel(s) treated, the techniques used (stenting, atherectomy, angioplasty), and the chronic total occlusion status of each vessel. Fluoroscopic images and procedural reports should support the services billed.
