Frequently Asked Questions About Code Set Standards Adopted Under HIPAA. What is a code set?


Under HIPAA, a "code set" is any set of codes used for encoding data elements, such as tables of terms, medical concepts, medical diagnosis codes, or medical procedure codes. Medical data code sets used in the health care industry include coding systems for diseases, impairments, other health related problems, and their manifestations; causes of injury, disease, impairment, or other health-related problems; actions taken to prevent, diagnose, treat, or manage diseases, injuries, and impairments; and any substances, equipment, supplies, or other items used to perform these actions. Code sets for medical data are required for data elements in the administrative and financial health care transaction standards adopted under HIPAA for diagnoses, procedures, and drugs.
