F31.11 corresponds to which bipolar episode classification?

• A. Mild, manic
• B. Moderate, manic
• C. Mild, depressed
• D. Severe, manic

Answer: (A)

Understanding how ICD-10-CM codes express both the mood state and its severity helps you see why this code matches mild mania. The base category is bipolar affective disorder (F31). When the current episode is manic, the code extension specifies that it is a manic episode, and the final decimal digit indicates severity. F31.11 encodes a manic episode with mild severity. This means the person exhibits manic symptoms such as elevated mood, increased energy, and reduced need for sleep, but the symptoms are not causing marked impairment or psychosis. If the episode were more severe, the code would carry a higher severity digit. So, the mild manic classification best fits F31.11.
