F90Attention-deficit hyperactivity disorders

F90 is the ICD-10-CM diagnosis code for Attention-deficit hyperactivity disorders. It belongs to block F90-F98 (behavioral and emotional disorders with onset usually occurring in childhood and adolescence) and chapter 5 (mental, Behavioral and Neurodevelopmental disorders). It is a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: F90.0 (type), F90.1 (type), F90.2 (type), F90.8 (type) and F90.9 (type).

The conditions in its Excludes2 note aren't part of F90, but may be coded alongside it if the patient has both: anxiety disorders (F40.-, F41.-), mood [affective] disorders (F30-F39), pervasive developmental disorders (F84.-) and schizophrenia (F20.-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
