HCC 229 (V28)

Unstable Angina and Other Acute Ischemic Heart Disease

25 ICD-10-CM codes map to this category in the CMS-HCC V28 risk adjustment model for payment year 2027. All 115 HCCs

Overridden by: HCC 228 (Acute Myocardial Infarction). If the patient also has one of these, only the higher HCC counts.
