Quick reference
- When to use
- Use F60.3 when the client demonstrates a pervasive, inflexible, and enduring pattern consistent with Borderline Personality Disorder that deviates from cultural expectations, causes distress or impairment, and is stable over time. Do not assign based on a single clinical encounter.
- Duration
- Personality disorders are enduring patterns — symptoms should be traceable to adolescence or early adulthood. Minimum of several sessions recommended before diagnosing. Reassess periodically as treatment may modify traits.
- Session codes
- Pair with CPT 90834/90837 for individual therapy. DBT programs: 90853 (group), 90834 (individual), plus phone coaching. 90791 for comprehensive evaluation. Long-term treatment is typical.
- Key indicators
- Enduring pattern of inner experience and behavior • Deviates from cultural expectations • Pervasive across situations • Onset in adolescence/early adulthood • Stable and long-standing • Distress or impairment
What F60.3 represents
BPD is characterized by a pervasive pattern of instability in interpersonal relationships, self-image, emotions, and marked impulsivity. It affects approximately 1.6% of the adult population and is one of the most commonly treated personality disorders.
Key diagnostic criteria
5+ of 9 criteria:
- Frantic efforts to avoid real or imagined abandonment
- Pattern of unstable, intense relationships
- Identity disturbance: markedly unstable self-image
- Impulsivity in 2+ areas that are self-damaging
- Recurrent suicidal behavior, gestures, threats, or self-mutilating behavior
- Affective instability due to marked mood reactivity
- Chronic feelings of emptiness
- Inappropriate, intense anger
- Transient, stress-related paranoid ideation or severe dissociative symptoms
Documentation essentials
Document specific criteria met. Assess and document suicide/self-harm risk thoroughly. Note patterns across time and situations.
Differential diagnosis
Distinguish from bipolar disorder (mood episodes vs. reactivity), PTSD (trauma-related vs. characterological), MDD, and other personality disorders.
Treatment planning
DBT is the most evidence-based treatment. MBT, TFP, and Schema Therapy also have evidence. Medication for specific symptoms rather than the disorder itself.
Insurance & billing
Accepted but may face authorization challenges for long-term treatment. Document medical necessity thoroughly.
Updates & changes
Alternative DSM-5 model (Section III) proposes dimensional approach to personality disorders.
Documentation pitfalls
Avoid stigmatizing language. Don't diagnose hastily – requires evidence of pervasive, long-standing patterns. Always assess safety.
