301.9
ICD-9-CMThis code represents a diagnosis of a personality disorder where the specific type cannot be determined or is not documented. It indicates a pervasive and enduring pattern of inner experience and behavior that deviates markedly from the expectations of the individual's culture, leading to distress or impairment, but without sufficient information to classify it further.
Use this code when a patient exhibits symptoms consistent with a personality disorder, but the provider's documentation does not specify a particular type (e.g., paranoid, borderline, narcissistic). This code is appropriate when the diagnostic criteria for a more specific personality disorder are not fully met or are not clearly articulated in the medical record.
