Sequelae of infectious diseases

International Classification of Diseases for Mortality and Morbidity Statistics, 11th Revision, v2024-01

A sequela is a chronic condition resulting from an acute condition and begins during that acute condition. The acute condition is no longer present. The sequela continues after the acute phase of the condition is resolved. For infectious diseases, the original infection is no longer present. The sequelae categories indicate infections as the cause of sequelae which are themselves classified elsewhere. Not to be used for chronic infections. Code the chronic infection to chronic or active infectious disease as appropriate. Use an additional code, if desired, to identify the specific sequelae.
