Anosognosia

This code represents anosognosia, a neurological condition characterized by a patient's lack of awareness or denial of their own neurological deficit or illness. Individuals with anosognosia genuinely believe they are not impaired, despite objective evidence to the contrary. It is often associated with brain injury or disease, particularly affecting the right hemisphere.

Use this code when documentation clearly indicates a patient's unawareness or denial of a specific neurological deficit, such as hemiplegia, blindness, or cognitive impairment, that is objectively present. This code is appropriate when the clinician explicitly diagnoses anosognosia, often in the context of stroke, dementia, or traumatic brain injury.

• Anosognosia is a manifestation, not a primary disease; always code the underlying neurological condition first.
• Ensure documentation explicitly states "anosognosia" or clearly describes the patient's lack of insight into their deficit.
• Do not confuse with simple denial (a psychological coping mechanism); anosognosia is a neurological phenomenon.
