Persistent mood [affective] disorders (F34)

The ICD-10 code section F34 covers persistent mood or affective disorders, which are long-lasting mood conditions affecting an individual's emotional state. These codes are used to classify different types of chronic mood disorders that differ from acute episodes.

This section includes specific codes such as F34.0 for cyclothymic disorder, a condition also known as cyclothymia or affective personality trait, characterized by fluctuating mood disturbances less severe than bipolar disorder. The F34.1 code represents dysthymic disorder, often referred to as dysthymia or early and late onset dysthymia, describing a persistent depressive mood lasting for years. Other codes like F34.81 identify disruptive mood dysregulation disorder, which involves severe irritability and mood swings in children. These codes help healthcare professionals and coders distinguish among various persistent mood disorders for accurate diagnosis and record-keeping. Using the correct ICD-10 code for persistent mood affective disorders ensures clear communication regarding the patient’s long-term mood conditions.
