ICD-10 Code F68 – Other disorders of adult personality and behavior (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F68 – Other disorders of adult personality and behavior
What it is
F68 covers adult personality or behavior disorders that do not fit a more specific ICD-10 category. Use it for persistent patterns affecting functioning when documentation supports this broader diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Records may describe unusual adult personality traits, problematic behavior patterns, or longstanding interpersonal difficulties that are not better classified elsewhere.
When to use this code
Use F68 when the clinician documents an adult personality or behavior disorder and no more specific code applies. It may fit cases with chronic maladaptive behavior, but check documentation for any named disorder or underlying condition.
Code only when the diagnosis is clearly stated in the record. If the note describes behavior concerns without a formal disorder diagnosis, check documentation before assigning F68.
Do not use for
Do not use F68 for specific personality disorders with their own codes, or for behavioral symptoms caused by another mental, neurologic, or medical condition. Check documentation.
Coding tip
Look for the exact diagnostic wording; if the provider names a specific disorder, code that more specific term instead of F68.
