Factitious disorder imposed on self, unspecified

This diagnosis code signifies a mental disorder where an individual intentionally produces or feigns physical or psychological signs or symptoms of illness in themselves. The primary motivation is to assume the sick role, without external incentives such as financial gain or avoiding work. The specific method or nature of the imposed illness is not specified.

Use this code when documentation clearly indicates a patient is deliberately fabricating or inducing symptoms of an illness upon themselves, and the specific type or manifestation of the factitious disorder is not detailed. This applies when the primary goal is to be perceived as ill, and there's no evidence of malingering or other external motivators. Supporting documentation would include psychiatric evaluations, behavioral observations, and a lack of objective medical findings consistent with reported symptoms.

• Differentiate from malingering (Z76.5), where there are clear external incentives for feigning illness.
• Ensure the documentation specifies "imposed on self" to distinguish from factitious disorder imposed on another (e.g., F68.A).
• This code is for unspecified types; if a specific manifestation is documented (e.g., predominantly psychological symptoms), a more specific code within the F68.1 category should be used.
