Question

A patient is admitted for chest pain. The patient was stabilized and discharged. In a subsequent admission, the patient was admitted as an outpatient for a left heart catheterization, coronary arteriography using two catheters and left ventricular angiography. The patient was found to have arteriosclerotic heart disease. The patient has no history of cardiac surgery. The appropriate sequencing of ICD-9 and CPT codes for the outpatient catheterization would be:

411.1-Intermediate coronary syndrome (unstable angina)
413.9- Other and unspecified angina pectoris
414.00-Coronary atherosclerosis of unspecified type of vessel, native or graft
414.01-Coronary atherosclerosis of native coronary artery
786.50-Chest pain, unspecified
93452-Left heart catheterization including intraprocedural injection(s) for left ventriculography, imaging supervision and interpretation, when performed
93453-Combined right and left heart catheterization including intraprocedural injection(s) for left ventriculography, imaging supervision and interpretation, when performed
93454-Catheter placement in coronary artery(s) for coronary angiography, including intraprocedural injection(s) for coronary angiography, imaging supervision and interpretation;
93458-with left heart catheterization including intraprocedural injection(s) for left ventriculography, when performed

Answer 1

The correct ICD-9 and CPT code sequencing for a patient who underwent outpatient left heart catheterization, coronary arteriography, and left ventricular angiography with a diagnosis of arteriosclerotic heart disease is 414.01 followed by 93458.

Step-by-step explanation:

The appropriate sequencing of ICD-9 and CPT codes for a patient admitted as an outpatient for a left heart catheterization, coronary arteriography using two catheters, and left ventricular angiography, who was found to have arteriosclerotic heart disease and has no history of cardiac surgery, would be as follows:

1. 414.01 - Coronary atherosclerosis of native coronary artery
2. 93458 - Left heart catheterization with coronary angiography including intraprocedural injection(s) for left ventriculography, imaging supervision and interpretation, when performed

The ICD-9 code for arteriosclerotic heart disease (414.01) should be listed first as it explains the reason for the catheterization procedure. The corresponding CPT code (93458) for the procedure would then follow it. This ensures accurate and specific coding for billing and medical records.
