Unspecified persistent mental disorders due to conditions classified elsewhere

This code signifies a chronic or long-standing mental disorder that is not otherwise specified, and is directly attributed to an underlying physical medical condition. It indicates that the primary cause of the mental health symptoms is a somatic disease or injury, rather than a primary psychiatric illness.

Use this code when documentation clearly states a persistent mental disorder (e.g., psychosis, mood disturbance, cognitive impairment) is a direct physiological consequence of a medical condition classified elsewhere, and a more specific mental disorder code is not applicable. This code is appropriate when the specific type of mental disorder is not fully elucidated or is generalized.

• Always sequence the underlying physical condition first, as this code is secondary to the physiological cause.
• Avoid using this code if a more specific mental disorder due to a general medical condition (e.g., 293.xx) can be identified from the documentation.
• Ensure the medical record explicitly links the mental disorder to the "conditions classified elsewhere" to support code assignment.
