What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

Dysthymic disorder, also known as persistent depressive disorder, is a chronic form of depression characterized by a depressed mood that occurs for most of the day, for more days than not, for at least 2 years in adults (1 year in children and adolescents). While the symptoms may be less severe than major depression, they are long-lasting and can significantly impact daily functioning. Symptoms may include poor appetite or overeating, insomnia or sleeping too much, low energy, low self-esteem, poor concentration, and feelings of hopelessness.

Additional Information

This is a diagnosis code used for billing and medical record purposes. Treatment typically involves psychotherapy and may include antidepressant medications. The chronic nature requires ongoing management and support.
