Mood Disorder Due to a General Medical Condition Recording Procedures
In recording the diagnosis of Mood Disorder Due to a General Medical Condition, the clinician should note both the specific phenomenology of the disturbance, including the appropriate subtype, and the identified general medical condition judged to be causing the disturbance on Axis I (e.g., 293.83 Mood Disorder Due to Thyrotoxicosis, With Manic Features). The ICD-9-CM code for the general medical condition should also be noted on Axis III (e.g., 242.9 thyrotoxicosis).
A separate diagnosis of Mood Disorder Due to a General Medical Condition is not given if the depressive symptoms develop exclusively during the course of Vascular Dementia. In this case, the depressive symptoms are indicated by specifying the subtype With Depressed Mood (i.e., 290.43 Vascular Dementia, With Depressed Mood).
