AHA Coding Clinic® for ICD-9 - 1997 Third Quarter; Clarifications
Coronary Artery Disease
Please clarify the use of the fifth digits for code 414.0x. We are confused over what fifth digit to use. The patient has coronary artery disease and had a CABG done years earlier. He still has coronary artery disease, but the chart does not clearly state where. He is not in the hospital for treatment of the CAD (surgery or PTCA). Is code 414.00, Coronary atherosclerosis, of unspecified type of vessel, native or graft, used, or is code 414.01, Coronary atherosclerosis of native coronary artery, assigned to show the old occlusion of the native artery bypassed years earlier with the CABG, or is 414.05, Coronary atherosclerosis, of unspecified type of bypass graft, (new code effective 10/1/96) used since he had the CABG done earlier? ...

Article Overview
This article discusses a documentation clarification question about coronary artery disease coding in the context of prior coronary artery bypass grafting. It is aimed at coders who need help understanding how an article addresses fifth-digit use, unspecified documentation, and the distinction between native and graft-related coronary vessel coding in a general coding context.
Why This Topic Matters
Accurate classification of coronary artery disease depends on the documented anatomy and clinical context. This article matters because it helps coders interpret incomplete chart language in a way that supports consistent code assignment and reduces ambiguity.
