What This Code Means
I25.11 is the ICD-10-CM diagnosis code for atherosclerotic heart disease of native coronary artery with angina pectoris. I25.11 sits in the ICD-10-CM chapter for diseases of the circulatory system (i00-i99), within the section covering ischemic heart diseases (i20-i25).
Header codes like I25.11 cannot be reported on claims directly; they organize child codes that share clinical context. Coders should select the billable child code that matches the documented presentation and then verify its current source-backed HCC mapping. Do not infer a child code or risk adjustment value from the header alone.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for I25.11 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
