F32.9 is a billable ICD code used to specify a diagnosis of major depressive disorder, single episode, unspecified. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code F32 is used to code Major depressive disorder

Major depressive disorder (MDD) (also known as clinical depression, major depression, unipolar depression, or unipolar disorder; or as recurrent depression in the case of repeated episodes) is a mental disorder characterized by a pervasive and persistent low mood that is accompanied by low self-esteem and by a loss of interest or pleasure in normally enjoyable activities. The term "depression" is used in a number of different ways. It is often used to mean this syndrome but may refer to other mood disorders or simply to a low mood. Major depressive disorder is a disabling condition that adversely affects a person's family, work or school life, sleeping and eating habits, and general health. In the United States, around 3.4% of people with major depression die by suicide, and up to 60% of people who die by suicide had depression or another mood disorder.
