Unspecified disorder of adult personality and behavior

This code represents a broad, ill-defined mental health condition affecting an adult's personality and behavioral patterns. It signifies a persistent and pervasive disturbance in thinking, feeling, and relating to others that causes significant distress or impairment, but for which a more specific personality disorder diagnosis cannot be established.

This code is appropriate when documentation indicates a personality or behavioral disorder in an adult, but the specific diagnostic criteria for a more defined personality disorder (e.g., narcissistic, borderline, avoidant) are not met or are not clearly documented. It may be used in initial assessments where further diagnostic clarity is pending or when a clinician explicitly states an "unspecified personality disorder."

• Avoid using this code if documentation supports a more specific personality disorder (F60.x).
• Query the provider for clarification if a more precise diagnosis is suspected but not explicitly stated.
• This code should generally be a last resort when no other specific personality or behavioral disorder code can be assigned.
