About F44
F44 is the ICD-10-CM diagnosis code for dissociative and conversion disorders. It belongs to block F40-F48 (anxiety, dissociative, stress-related, somatoform and other nonpsychotic mental disorders) and chapter 5 (mental, Behavioral and Neurodevelopmental disorders). It is a header code, so it can't be reported by itself; one of its 9 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: F44.0 (amnesia), F44.1 (fugue), F44.2 (stupor), F44.4 (deficit), F44.5 (convulsions), F44.6 (deficit), F44.7 (presentation), F44.8 (disorders) and 1 more.
The conditions in its Excludes2 note aren't part of F44, but may be coded alongside it if the patient has both: malingering [conscious simulation] (Z76.5).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
