About coding Psychosyndrome
The ICD-10-CM code for Psychosyndrome is F07.9 (Unspecified personality and behavioral disorder due to known physiological condition).
Within F07, choose F07.9 (Unspecified personality and behavioral disorder due to known physiological condition) only when documentation doesn't support a more specific option: personality change due to known physiological condition (F07.0) and other personality and behavioral disorders due to known physiological condition (F07.8).
Code first: the underlying physiological condition.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
