Developmental anomalies is a chapter in ICD-11 that includes conditions resulting from abnormalities in the formation, growth, or differentiation of organs, tissues, or body systems that occur during prenatal development. These anomalies may be structural, functional, or genetic in nature and can affect a single organ or multiple systems, leading to varying degrees of impairment or disability.
This chapter encompasses a wide range of congenital conditions such as malformations, deformations, chromosomal abnormalities, and genetic syndromes. Accurate classification supports early diagnosis, clinical management, genetic counseling, and long-term care planning, while also contributing to research, surveillance, and preventive strategies aimed at reducing the impact of developmental anomalies.
