Cumulative Official WHO Updates to ICD 10 - 1996 - 2001

Duplication occurs frequently when one ICD-10-CM code has multiple Health Topics, some unrelated, because of the different ICD-9-CM codes mapped to the one ICD-10-CM code. All the Health Topics previously assigned to the 9-CM codes are then mapped to the one 10-CM code. These 10-CM codes require manual review. ................
