Mood disord d/t physiol cond w major depressive-like epsd

This diagnosis code signifies a mood disturbance characterized by symptoms consistent with a major depressive episode, directly attributable to an underlying medical condition or substance use. The physiological condition is considered the primary etiology of the depressive symptoms, not merely a comorbidity.

Apply this code when documentation clearly links a patient's major depressive-like symptoms (e.g., anhedonia, persistent sadness, sleep disturbance, fatigue) to a specific, known physiological condition such as a neurological disorder, endocrine imbalance, or adverse effect of medication. The physician's assessment must establish a direct causal relationship.

• Always code the underlying physiological condition first, followed by this code.
• Ensure documentation explicitly states the mood disorder is "due to" or "secondary to" the physiological condition.
• Distinguish from F32.x (Major depressive disorder, single episode) or F33.x (Major depressive disorder, recurrent) where no direct physiological cause is identified.
