Original Question

Preoperative diagnosis: Coronary artery disease Postoperative diagnosis: Two-vessel coronary disease with ejection fraction of 60 to 65 percent Procedures performed: Left heart catheterization, left ventriculogram, and coronary angiography via the left femoral artery Indications: This is an elderly male with palpitations with no significant chest discomfort and no previous cardiac history. Echocardiogram showed cardiomyopathy, ejection fraction of 60 percent, with slow heart movement globally. A cardiac catheterization was recommended to determine the cause of his cardiomyopathy. Risks and benefits were explained, and informed consent was obtained. Procedure: The patient was prepped and draped in a sterile manner, and the left groin was anesthetized with 1 percent plain lidocaine. Entry into the right femoral artery was accomplished by means of a single-wall puncture. A guidewire was inserted into the left femoral artery, and a hemostatic sheath with its dilator was advanced over the guidewire into the left femoral artery. The guidewire and dilator were removed, and the hemostatic sheath was flushed with normal saline. A pigtail catheter was inserted with its guidewire and passed into the left ventricular chamber. The pigtail catheter was connected to the injection system, and left ventricular pressures were obtained. Left ventriculogram was obtained. The catheter was removed, leaving the guidewire in place. The left coronary catheter was advanced over the guidewire to the aortic root and left main coronary artery; the guidewire was removed and the catheter connected to the injection system, and multiple injections of the left coronary system were completed. At this time the injection system was disengaged from the catheter, and the left coronary catheter was removed, leaving the guidewire in place; a right coronary catheter was then advanced over the guidewire up to the aortic root and attached to the injection system. The catheter was then placed into the right coronary artery, and views were obtained. The injection system was then disconnected from the catheter, and the catheters were removed. Findings: The left heart systemic blood pressure was 128/72 and left ventricular end-diastolic pressure 20 mmHg. Left ventriculogram demonstrated mild global hypokinesis with ejection fraction 60 to 65 percent. There was no significant mitral regurgitation, and the aortic valve appeared normal. The left anterior descending had 20 to 25 percent distal narrowing. The remainder of the left anterior descending was free of focal stenosis. The left circumflex was found to have 30 percent smooth, discrete narrowing in the proximal portion. The right coronary artery was found to be free of narrowing or focal stenosis. Process 3: Modifiers Was the procedure performed different from that described by the nomenclature of the code? Was the procedure performed at an anatomical site that has laterality? Was the procedure performed in the global period of another procedure? Were additional procedures performed during the operative session, and does the documentation support them? Did the surgeon have help from another surgeon or another appropriate person? Did a physician different from the surgeon provide the preoperative or postoperative portion of the procedure? What modifier(s) should be appended to the CPT code for this case? 59 51 LD, LC, and RC None
