Administrative databases have increasingly become a platform for clinical investigations
aiming to address trends in the prevalence, patterns of care, and outcomes of major
cardiovascular diseases including strokes.

Identification of acute ischemic stroke (AIS) events in these databases is dependent
on billing codes. Hence, accurate querying of administrative databases for research
purposes require proper validation of those billing codes. Several studies have previously
validated the use of certain International Classification of Diseases-Ninth Revision-Clinical
Modification (ICD-9-CM) codes to discern hospitalizations for AIS. However, on October
1, 2015, the Center for Medicare and Medicaid Services transitioned from ICD-9-CM
to ICD-10-CM compendium of codes for diagnosis and billing in health care. To our
knowledge, no studies have yet assessed the accuracy of ICD-10-CM codes in identifying
patients admitted with AIS.To read this article in full you will need to make a payment
