New coding system target date is 2013, according to final rule. You'll have to ensure compliance with ICD-10 by the effective date of Oct. 1, 2013, according to Jan. 15 release by the Department of Health and Human Services. The new edition of the ICD manual will expand the code set from 17,000 codes, which ICD-9-CM currently has, to more than 155,000 codes, which ICD-10 includes. "HHS received more than 3,000 comments on the ICD-10 proposed rule, and support for transition to the ICD-10-CM and ICD-10-PCS is strong throughout the healthcare industry," says Kerry Weems, acting CMS administrator.
