NASTAD Health Systems Data Technical Resource: Toolkit for Querying Claim Databases for HCV Testing and Treatment

Last Updated

This toolkit provides a list of diagnosis, procedure, and prescription drug codes to help health departments develop claims data queries to monitor HCV testing, identify individuals diagnosed with HCV, and examine their services and treatment utilization. Most people living with HCV do not know they are infected, and for individuals who are diagnosed with HCV infection, they often do not get linked to appropriate care for their HCV infection. Chronic hepatitis C can lead to serious complications such as cirrhosis, liver cancer, and liver failure. These complications can be prevented through early detection and treatment.
