F06.31 diagnosis code: Mood disorder due to known physiological condition with depressive features
F06.31 is the ICD-10-CM code for diagnosing mood disorder due to a general physiological condition with depressive features. As with other mental disorders due to medical conditions, this code represents cases where a mood disorder has arisen as a direct consequence of a physiological condition, with symptoms primarily reflecting depression.
It involves mood disturbances characterized by markedly diminished interest or pleasure in all or almost all activities and low mood. Examples of physiological conditions include hypothyroidism, Parkinson's disease, and stroke.
The coding assumes a causal relationship between the physiological state and the mood disturbance.
