CPT® Code 92984

Deleted

1. Indications

The procedure coded under CPT® 92984 is indicated for patients who present with significant coronary artery disease, characterized by blockages in multiple coronary arteries that may lead to ischemic heart conditions. The following conditions may warrant the performance of this procedure:

• Coronary Artery Disease (CAD) - A condition where the coronary arteries are narrowed or blocked due to plaque buildup, leading to reduced blood flow to the heart muscle.
• Angina Pectoris - Chest pain or discomfort that occurs when the heart muscle does not receive enough blood, often triggered by physical activity or stress.
• Myocardial Infarction - Also known as a heart attack, this condition occurs when blood flow to a part of the heart is blocked, causing damage to the heart muscle.
• Positive Stress Test Results - Indications from a stress test that suggest significant coronary artery blockage, necessitating further intervention.

2. Procedure

The procedure for CPT® 92984 involves several critical steps to ensure successful angioplasty of each additional coronary artery. The following outlines the procedural steps:

• Step 1: Preparation - The patient is positioned appropriately, and the skin over the access site, typically the femoral artery, is cleaned and sterilized to prevent infection. Local anesthesia may be administered to minimize discomfort during the procedure.
• Step 2: Accessing the Artery - A needle is used to puncture the selected artery, and a sheath is inserted to provide a pathway for the subsequent instruments. This sheath remains in place throughout the procedure to facilitate access to the coronary arteries.
• Step 3: Guidewire Insertion - A guidewire is carefully inserted through the sheath and advanced through the aorta to the site of the blockage in the coronary artery. This guidewire serves as a track for the angioplasty catheter.
• Step 4: Catheter Advancement - A catheter with a balloon tip is threaded over the guidewire and navigated to the occluded area of the coronary artery. The positioning of the catheter is critical for effective treatment.
• Step 5: Balloon Inflation - Once the catheter is in place, the balloon at the tip of the catheter is inflated. This inflation compresses the plaque against the arterial wall, widening the artery and restoring blood flow. The balloon may be inflated multiple times as needed to achieve the desired outcome.
• Step 6: Withdrawal of Catheter - After the balloon inflation is completed, the catheter is carefully withdrawn from the artery.
• Step 7: Completion Angiography - A contrast agent is injected through the catheter to visualize the treated area. A completion angiography is performed to confirm that the artery is patent and that blood flow has been successfully restored.

3. Post-Procedure

After the completion of the angioplasty procedure coded under CPT® 92984, the patient is typically monitored for any complications or adverse reactions. Post-procedure care may include the following considerations:

• Monitoring - Patients are usually monitored in a recovery area for vital signs and any signs of complications, such as bleeding or changes in heart rhythm.
• Activity Restrictions - Patients may be advised to limit physical activity for a specified period to allow for proper healing and to reduce the risk of complications.
• Follow-Up Care - Follow-up appointments are essential to assess the success of the procedure and to manage any ongoing treatment for coronary artery disease.
• Medication Management - Patients may be prescribed antiplatelet medications or other drugs to prevent clot formation and to support heart health following the procedure.
