ICD-10

The International Statistical Classification of Diseases and Related Health Problems 10th Revision (ICD-10) is a set of codes classified by the World Health Organization (WHO) used by physicians, hospitals, and other healthcare organizations to identify patient diagnosis and medical procedures. In the United States, the codes are used by providers and payers for many uses within health care systems, including patient care decision support and claims adjudication.

The ICD-10-CM and ICD-10-PCS code sets replace the current ICD-9 diagnosis and procedure codes. The ICD-10 code sets that replace the ICD-9 codesets are required for all HIPAA transactions, including outpatient claims (with dates of service), and inpatient claims (with dates of discharge), on and after October 1, 2013. The change to ICD-10 impacts coding for all HIPAA participants.
