Mood disorder due to known physiol cond w depressv features

This diagnosis code signifies a mood disturbance characterized predominantly by depressive symptoms that are directly attributable to an underlying medical condition or substance. The physiological condition is considered the primary etiology for the depressive features, rather than an independent primary mood disorder.

Apply this code when documentation clearly links depressive symptoms (e.g., anhedonia, low mood, fatigue) to a known physiological cause, such as hypothyroidism, neurological disorders, or medication side effects. The medical record must explicitly state the causal relationship between the physiological condition and the mood disturbance.

• Always sequence the underlying physiological condition first, followed by this code.
• Ensure documentation specifies "depressive features" to differentiate from other mood presentations.
• Avoid using this code if the depressive symptoms are better explained by an adjustment disorder or a primary depressive disorder.
