Note: On October 1, 2015 the conversion from the 9th version of the International Classification of Diseases (ICD-9-CM) to version 10 (ICD-10-CM) occurred. Regardless of when a claim was submitted for payment, services that occurred prior to October 1, 2015, use ICD-9 codes. Chronic conditions identified in 2015 are based upon ICD-9 codes for the first ¾ of the year (January-September) 2015 and ICD-10 codes for the last quarter of the year (October-December). Starting in 2016, chronic conditions identified are based upon ICD-10 codes for the full year. Detailed information on the identification of chronic conditions in the CCW is available at http://www.ccwdata.org/chronic-conditions/index.htm.
