Although the International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10), is used elsewhere around the globe, U.S. proposals to move from the ninth to the 10th revision have faltered because of congressional delays, among other reasons.

Physician reimbursements and quality scores will increasingly depend on the completeness, as well as accuracy and specificity, of diagnosis coding for risk adjustments. This commentary explains why it is time to move to the ICD-10.
