ICD Code F31.9

ICD code F31.9 is used to classify a diagnosis of bipolar disorder when the specific type or phase of the disorder is not specified. This code is applied when a healthcare provider identifies symptoms consistent with bipolar disorder but does not have enough information to categorize it into a more specific subtype, such as bipolar I or bipolar II. This code helps in documenting the condition for treatment planning and insurance billing purposes, ensuring that the patient receives appropriate care while the healthcare provider gathers more detailed information about the disorder.

1. Presence of Mood Episodes: The individual must exhibit episodes of mood disturbances that include periods of elevated, expansive, or irritable mood, as well as periods of depression. These episodes should not be attributable to any specific type of bipolar disorder.

2. Manic or Hypomanic Symptoms: During the elevated mood episodes, the individual may experience symptoms such as increased energy, decreased need for sleep, grandiosity, talkativeness, racing thoughts, distractibility, or involvement in activities with a high potential for painful consequences.

3. Depressive Symptoms: During depressive episodes, the individual may experience symptoms such as persistent sadness, loss of interest or pleasure in activities, significant weight change, insomnia or hypersomnia, fatigue, feelings of worthlessness or excessive guilt, diminished ability to think or concentrate, or recurrent thoughts of death.

4. Impact on Functioning: The mood episodes must cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.

5. Exclusion of Other Disorders: The symptoms should not be better explained by another mental disorder, such as schizoaffective disorder, schizophrenia, or other psychotic disorders.

6. Exclusion of Substance or Medical Condition: The mood disturbances should not be attributable to the physiological effects of a substance (e.g., drug abuse, medication) or another medical condition.

7. Lack of Specificity: The diagnosis is used when the specific type of bipolar disorder cannot be determined due to insufficient information or when the symptoms do not meet the full criteria for any specific type of bipolar disorder.
