How does Q02 relate to ICF functioning codes?

ICF (International Classification of Functioning, Disability and Health) codes describe how conditions like microcephaly affect a person's functioning — body functions, activities, participation, and environmental factors. AutoICD provides ICF Core Sets for 12+ conditions and can map clinical text to ICF categories automatically. Browse the ICF directory to explore functioning codes.

What is the ICD-11 equivalent of Q02?

Q02 maps to the ICD-11 code: LA05.0 (Microcephaly).
