Which code corresponds to Severe, depressed?

• A. F31.11
• B. F31.13
• C. F31.4
• D. F31.31

Answer: (C)

In ICD-10-CM coding for bipolar disorders, the F31 series is used for bipolar affective disorder, and the digits after the decimal specify the current mood episode and its severity. When the patient is in a depressive episode and the depression is severe, the specifier is the decimal 4, giving the code for this state as F31.4. The other codes reflect other combinations (different mood states like mania or less severe depression, or other specifiers), which don’t match the description of a severe depressive episode.
