Some expanded code sets, like ICD-10-CM, have over 70,000 codes. Many more new diagnoses can be tracked using ICD-10 than with ICD-9. ICD-10 is required for use by physicians and healthcare providers under the Health Insurance Portability & Accountability Act (HIPAA) and will replace all ICD-9 code sets. This medical classification list is generated by the World Health Organization (WHO), and is used to help healthcare providers identify and code health conditions. ICD-10 codes are the byproduct of that revision. ICD (International Statistical Classification of Diseases and Related Health problems) is now on its 10th revision.
