ICD-10 Code F68.1 – Factitious disorder imposed on self (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F68.1 – Factitious disorder imposed on self
What it is
F68.1 identifies factitious disorder imposed on self, a condition in which you document intentional falsification or induction of symptoms without obvious external reward. The behavior is aimed at assuming the sick role.
Clinical signs
Clinical features vary; refer to documentation. Common clues include inconsistent histories, unexplained or self-induced findings, and repeated care-seeking with symptoms that do not fit observed results.
When to use this code
Use F68.1 when the record clearly states factitious disorder imposed on self or describes deliberate symptom fabrication, exaggeration, or self-inflicted illness behavior. You may also use it when the clinician documents Munchausen-type behavior. Check documentation if intentional deception is not explicit.
Do not use for
Do not use this code for malingering, where symptoms are produced for external gain, or for somatic symptom disorder, where symptoms are not intentionally fabricated. If the note only says “rule out” or “suspected,” check documentation.
Coding tip
Code only when the provider documents intentional falsification or induction of symptoms; vague concern for “unexplained complaints” is not enough.
