Coding guidance (WHO 2019)
A group of disorders characterized by qualitative abnormalities in reciprocal social interactions and in patterns of communication, and by a restricted, stereotyped, repetitive repertoire of interests and activities. These qualitative abnormalities are a pervasive feature of the individual's functioning in all situations. Use additional code, if desired, to identify any associated medical condition and mental retardation.
