Coronary Artery, Number of Arteries
The body part values for specifying procedures on the coronary arteries were revised from the number of sites to the number of arteries. From To Body Part Body Part 0 Coronary Artery, One Site 0 Coronary Artery, One Artery 1 Coronary Artery, Two Sites 1 Coronary Artery, Two Arteries 2 Coronary Artery, Three Sites 2 Coronary Artery, Three Arteries 3 Coronary Artery, Four or More Sites 3 Coronary Artery, Four or More Arteries According to the ICD-10-PCS Official Guidelines for Coding and Reporting, “The coronary arteries are classified as a single body part that is further specified by...

Article Overview
This article is a coding update focused on ICD-10-PCS coronary artery body-part classification. It explains a revision in how coronary arteries are counted for procedure coding, identifies the procedure table families affected, and includes a CABG-oriented clinical coding scenario for readers who work with cardiovascular inpatient coding and procedure assignment.
Why This Topic Matters
Accurate coronary artery counting affects ICD-10-PCS procedure selection for cardiovascular cases, especially bypass and other interventional procedures. The article is relevant for coders, auditors, CDI professionals, and trainers who need to align coronary artery procedure coding with current PCS body-part logic and table structure.
