About the F30–F39 Code Range
ICD-10 codes F30-F39 cover mood or affective disorders, which include various types of manic, bipolar, depressive, and persistent mood conditions. These codes help classify different episodes and severities such as manic episodes, bipolar disorder phases, and depressive episodes, whether mild, moderate, or severe.
This code range is used to specify mood disorders like manic episodes (F30), including those without and with psychotic symptoms, and their remission status. Bipolar disorder (F31) codes detail current episodes—hypomanic, manic, depressed, or mixed—and the disorder’s remission phases, also covering bipolar II and other variants. Codes F32 and F33 refer to single and recurrent major depressive episodes, respectively, with classification based on severity and presence of psychotic features. Persistent mood disorders such as cyclothymic disorder and dysthymic disorder fall under F34, with specific codes for disruptive mood dysregulation disorder. Lastly, F39 captures unspecified mood disorders. The synonyms provided, like "manic disorder," "bipolar affective disorder," or "major depressive disorder," link common terms directly to these precise codes to aid medical coders and healthcare professionals in accurate diagnosis and documentation.
