Factit disord impsd on self, with predom physcl signs/symp

This code represents a psychiatric condition where an individual intentionally produces or feigns physical signs or symptoms of illness in themselves. The primary motivation is to assume the sick role, without external incentives like financial gain or avoiding work. The deception is often elaborate and persistent, leading to unnecessary medical investigations and treatments.

Use this code when documentation clearly indicates a patient is deliberately fabricating or inducing physical symptoms or signs of illness upon themselves. This diagnosis requires evidence that the patient is consciously deceiving healthcare providers about their health status, and that the predominant presentation involves physical manifestations rather than psychological ones.

• Differentiate from malingering (Z76.5), where there are clear external incentives for feigning illness.
• Requires thorough documentation of the patient's deceptive behaviors and the absence of a genuine underlying medical condition explaining the symptoms.
• Do not use for Munchausen syndrome by proxy; that involves imposing symptoms on another.
