ICD-10 Background

The International Classification of Diseases (ICD) is the international standard diagnostic classification for general epidemiological, health management, and clinical use.  As part of HIPAA Administrative Simplification, the United States HHS mandated that all health care entities upgrade diagnosis (ICD-9-CM) and inpatient procedure codes (ICD-9-PCS) to ICD-10-CM and ICD-10-PCS, respectively. The ICD-10 code set is a full replacement of the ICD-9 code set that will provide additional granularity for diagnosis and procedure codes.

All discharges and services with a date of service on or after October 1, 2015 will need ICD-10 codes. Please select the link to view the final rule (PDF*)
