Autism Spectrum Disorder (ASD) is a group of neurodevelopmental disorders that are characterised by difficulties in communication, social interaction, as well as restricted interests and resistance to change (Underwood et al, 2019). These codes have been taken from previously validated code lists (Underwood et al, 2021). Pathological demand avoidance (Eu846) and Rett Syndrome (Eu842) have been excluded from this list based on clinical (Prof Ann John) and expert (Underwood) advice and due to the fact they are not included in the DSM or ICD-10.
