AHA Coding Clinic® for ICD-10-CM and ICD-10-PCS - 2022 Issue 4; New/Revised ICD-10-CM Codes
Refractory Angina Pectoris
A unique code has been created for refractory angina pectoris, as well as new codes identifying refractory angina pectoris with atherosclerosis of the native coronary artery and of the following bypass grafts: unspecified, autologous vein and artery, nonautologous biological, native coronary artery of transplanted heart, and bypass graft of other coronary artery as follows: I20.2 Refractory angina pectoris I25.112 Atherosclerotic heart disease of native coronary artery with refractory angina pectoris I25.702 Atherosclerosis of coronary artery bypass graft(s), unspecified, with refractory angina pectoris I25.712 Atherosclerosis of autologous vein coronary artery bypass graft(s) with refractory angina pectoris...

Article Overview
This article covers a focused ICD-10-CM update on refractory angina pectoris and related atherosclerotic heart disease classifications, including codes tied to native coronary disease and several bypass-graft contexts. It is useful for coders, CDI staff, and clinicians who document or code chest-pain and coronary artery disease encounters, especially when distinguishing refractory angina from other angina presentations. The article also includes a brief clinical encounter example and indicates how the update supports more precise data collection and reporting.
Why This Topic Matters
Refractory angina pectoris received dedicated ICD-10-CM coding, and the article helps readers understand the scope of the new diagnosis categories so records can be coded consistently and tracked more accurately.
