Congenital anomalies from the health surveillance perspective: compilation of a list based on ICD-10

Abstract

Objective. Propose a list of congenital anomalies with corresponding codes in the tenth revision of the International Classification of Diseases (ICD), aiming at application in the scope of health surveillance. Methods. In December 2019, the following sources were searched: ICD-10, ICD-11, abnormalities monitored by three surveillance programs, and a database of rare diseases (Orphanet). The Abnormalities were extracted from these data sources, processed based on the ICD-10 and compiled with manual review. Results. 898 codes were identified, of which 619 (68.3%) were in Chapter XVII of ICD-10. Of the 279 codes in other chapters, 19 were exclusive of the ICD-11 search, 72 of the surveillance programs, 79 of the Orphanet and 36 of the ICD-10 search for terms. Conclusion. The codes contained in chapter XVII of ICD-10 do not capture the totality of congenital anomalies, indicating the need of adopting of an expanded list.
