Mood disorder due to known physiol cond w manic features

This code signifies a mood disturbance characterized by elevated, expansive, or irritable mood, increased activity, and other manic symptoms, directly resulting from a specific medical illness or substance. The underlying physiological condition is considered the primary cause of the psychiatric symptoms.

Apply this code when documentation clearly links manic symptoms to a diagnosed physiological condition (e.g., hyperthyroidism, neurological disorder, medication side effect). The medical record must explicitly state that the mood disorder is "due to" or "secondary to" the identified physical illness.

• Always sequence the underlying physiological condition first, followed by this code.
• Ensure documentation specifies "manic features" and not just a general mood disturbance.
• Differentiate from substance-induced mood disorders or primary bipolar disorder.
