aThis congestive heart failure definition is used in the Charlson Comorbidity Index. The stroke risk definition does not include the codes 402.01-404.93 but does include additional codes 425.0-425.3, 674.5, 674.53, and 674.54.
bThis diabetes mellitus definition is for stroke risk. The Charlson Comorbidity Index definition24 is limited to 249* and 250*.
ICD-9-CM = International Classification of Diseases, Ninth Revision, Clinical Modification; TIA = transient ischemic attack.
