Unspecified nonpsychotic mental disorder following organic brain damage

This code signifies a mental health condition that is not characterized by psychosis, arising as a direct consequence of damage to the brain. The specific type of mental disorder is not further identified, indicating a broad range of nonpsychotic symptoms such as mood disturbances, anxiety, or personality changes that are directly attributable to an organic brain injury or disease.

Use this code when documentation clearly links a nonpsychotic mental disorder to a previously diagnosed or identified organic brain injury or disease, but the specific mental disorder is not specified (e.g., "mental changes due to head injury"). This code is appropriate when the clinician has identified a mental health issue stemming from brain damage, but has not provided a more precise psychiatric diagnosis.

• Always seek more specific documentation if possible; this is a residual category.
• Ensure the medical record explicitly states the mental disorder is "following" or "due to" organic brain damage.
• Sequence this code after the underlying organic brain condition (e.g., traumatic brain injury, stroke) if it is still active.
