• F31.31 is an ICD-10-CM code used to diagnose a current episode of mild depression within bipolar disorder.

• The code requires a history of at least one manic or hypomanic episode, characterizing the bipolar disorder diagnosis.
• The 'mild' tag signifies that the symptoms, while identified, are not significantly disrupting the patient's daily life. So, don't use it for those with major depressive episodes.
• The patient must be confirmed to have bipolar disorder. This can't be used if the patient isn't, even if they have mild/major depressive disorder.

Clinical information

• Bipolar disorder is characterized by periods of dramatically elevated mood (mania or hypomania) and drastically low mood (depression). It is a manic-depressive illness.
• A person diagnosed with F31.31 is currently in a depressive phase classified as mild.
• Symptoms during this phase may include sadness, decreased energy, minor sleep disturbances, and reduced interest in activities they usually enjoy.
• While distressing, these symptoms are manageable and don't significantly interfere with the person's daily routine.
• Ongoing treatment, typically a combination of medications and psychotherapy, is necessary to manage bipolar disorder.
• As mentioned earlier, this is only for mild cases. If you're wondering if you can use this for mild or moderate severity, please note that F31.32 is for moderate cases. F31.4 and F31.5 are for the current episode depressed, severe (the former is for those without psychotic features, the latter with psychotic features).
• This cannot be used for current episode manic, severe (or moderate or mild) cases.
