Q86.8: Other congenital malformation syndromes due to known exogenous causes

Conditions falling under "Other congenital malformation syndromes due to known exogenous causes" are disorders that an individual is born with because of external factors affecting the development of the fetus during pregnancy. These factors can include medications, recreational drugs, alcohol, infections, exposure to harmful chemicals or radiation. These conditions present themselves at birth and vary widely in their impact on the individual. They could affect almost any part of the body and lead to physical abnormalities such as malformed limbs or organs, cognitive defects, sensory issues, or growth impairments. Symptoms and their severity can be different for each child depending on the specific malformation and the part of the body it affects. Generally, these syndromes are not transmitted, but are the result of direct exposure to the fetus by external factors during critical periods of development.
