Frequently Asked Questions

When should I use F61 instead of F60?

Use F61 when personality disorder features are present from multiple categories (e.g., borderline, avoidant, and dependent traits) and no single type clearly predominates. If one type is clearly predominant, code that specific F60 subtype.
