About ICD-9-CM 433.11
433.11 is an ICD-9-CM diagnosis code for occlusion and stenosis of carotid artery with cerebral infarction. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.
The CMS General Equivalence Mappings translate it to 2 ICD-10-CM codes, such as I63.139 (Cerebral infarction due to embolism of unspecified carotid artery) and I63.239 (Cerebral infarction due to unspecified occlusion or stenosis of unspecified carotid artery). All of these are approximate matches, so review the record to pick the right one.
