In early 2009, the United States Department of Health and Human Services (HHS) announced a final rule that called for the replacement of the current ICD-9 code set used to report healthcare diagnoses and procedures with the ICD-10 code set by October 1, 2013. The adoption of the new system offers several benefits, including the facilitation of quality data reporting, support for pay for performance payment methodologies, improved billing accuracy, and allowances for international comparison of the incidence and spread of disease.
