International Classification of Diseases

Last updated: 10/3/2025

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

Fibromyalgia is a chronic disorder characterized by widespread musculoskeletal pain, tenderness at specific points on the body, and often accompanied by fatigue, sleep disturbances, and mood issues. The pain is typically described as a constant dull ache that occurs on both sides of the body and above and below the waist. This condition affects how the brain and spinal cord process pain signals, often amplifying painful sensations.

Additional Information

Fibromyalgia is a diagnosis of exclusion, meaning other conditions must be ruled out first. Treatment typically involves a multidisciplinary approach including medications, exercise, stress reduction, and sleep management.
