Mood disorder due to known physiol cond w mixed features

This code signifies a mood disturbance characterized by symptoms of both depression and mania/hypomania occurring simultaneously, directly attributed to an underlying medical condition. The physiological condition is the primary cause of the mood symptoms, not merely a precipitating factor.

Apply this code when documentation clearly links a patient's mixed mood symptoms (e.g., elevated mood with psychomotor retardation, or depressed mood with racing thoughts) to a specific, identifiable physiological illness or substance. Examples include mood changes secondary to endocrine disorders, neurological conditions, or medication side effects.

• Always sequence the underlying physiological condition first, followed by this code.
• Ensure documentation explicitly states the causal link between the medical condition and the mixed mood symptoms.
• Differentiate from F38.8 (Other specified mood disorders) when the physiological cause is unknown or not clearly established.
