Two algorithms were assessed for ICD\u201010\u2010CM: validated ICD\u201010 codes in the literature and codes translated from ICD\u20109\u2010CM using an established mapping algorithm. We used segmented regression analysis on time\u2010series data to examine changes in the 3\u2010month prevalence (both level and trend) before and after the ICD\u201010\u2010CM implementation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Significant changes in the level were found in 19 and 11 conditions when using the ICD\u201010 codes from the literature and mapping algorithm, respectively. The conditions with inconsistent levels by both of the algorithms were valvular heart disease, peripheral vascular disease, mild liver disease, moderate to severe liver disease, metastatic cancer, rheumatoid arthritis and collagen vascular diseases, coagulopathy, blood loss anemia, deficiency anemia, alcohol abuse, and psychosis. Nine conditions had significant changes in the trend when using the ICD\u201010 codes from the literature or mapping algorithm.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Less than half of the 32 conditions studied had a smooth transition between the ICD\u20109\u2010CM and ICD\u201010\u2010CM coding systems.
