Cumulative Official WHO Updates to ICD 10 - 1996 - 2001

Note: ICD-10 codes started October 1, 2015. On October 1, 2016 Medicare required that hospitals use the full specificity of an ICD-10 code when they bill. Because of this there are many forward mapped DRG’s that changed to 999 because the code was not as specific as the grouper required. ................
