ICD-10 Code F60.9 – Personality disorder, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F60.9 – Personality disorder, unspecified
What it is
F60.9 identifies a personality disorder when the documentation confirms a personality disorder but does not specify the type. Use it for enduring patterns of inner experience and behavior that differ from expectations and cause impairment.
Clinical signs
Clinical features vary; refer to documentation. Common descriptions include long-standing difficulties in thinking, feeling, relating to others, or controlling impulses, with problems evident across settings and not limited to a single episode.
When to use this code
Use this code when the provider documents “personality disorder” without naming a subtype such as paranoid, borderline, or avoidant. It is also appropriate when the record confirms a personality disorder but the specific category is not established. Check documentation for any more specific diagnosis before coding.
Do not use for
Do not use F60.9 when a specific personality disorder subtype is documented or supported in the record. Do not use it for temporary mood, anxiety, or adjustment problems that do not represent a personality disorder.
Coding tip
Query the provider if the note says only “personality disorder” and a more specific type may be available.
