ICD-10 Resource Center

ICD-10-CM is the United States' clinical modification of the World Health Organization's (WHO) International Classification of Diseases (ICD) 10th Revision. It is used to classify diseases and causes of illness recorded on health records, claims, and other vital information. ICD-10-PCS is the procedure classification system used to report hospital inpatient procedures.

The U.S. Department of Health and Human Services ("HHS") issued a ruling in 2009 that required covered entities (health plans, health care providers, and health care clearinghouses) that conduct electronic HIPAA standard transactions to move from ICD-9 to the next generation ICD-10 code sets by October 1, 2014. However, with the enactment of the Protecting Access to Medicare Act of 2014, the Secretary of Health and Human Services may not, prior to October 1, 2015, adopt ICD-10 code sets. The Centers for Medicare and Medicaid Services (CMS) is examining the implications of the ICD-10 provision and will provide guidance to providers and stakeholders soon. The transition does not affect the Current Procedural Terminology (CPT®) code set, which will continue to be used for outpatient services.
