About coding Lycanthropy
The ICD-10-CM code for Lycanthropy is F22 (Delusional disorders).
Don't report F22 together with the conditions in its Excludes1 note: mood [affective] disorders with psychotic symptoms (F30.2, F31.2, F31.5, F31.64, F32.3, F33.3) and paranoid schizophrenia (F20.0).
The conditions in its Excludes2 note aren't part of F22, but may be coded alongside it if the patient has both: paranoid personality disorder (F60.0), paranoid psychosis, psychogenic (F23) and paranoid reaction (F23).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for F22)
