About coding traumatic post porencephaly
The ICD-10-CM code for traumatic post porencephaly is F07.89 (Other personality and behavioral disorders due to known physiological condition).
Within F07.8, choose F07.89 (Other personality and behavioral disorders due to known physiological condition) only when documentation doesn't support a more specific option: Postconcussional syndrome (F07.81).
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.
