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

This code describes a condition where there is abnormal function or restriction in the sacral region (the triangular bone at the base of the spine that connects to the pelvis). 'Segmental dysfunction' refers to problems with individual vertebral segments, while 'somatic dysfunction' indicates issues with the body's structural components including muscles, fascia, and joints. This can cause pain, stiffness, and restricted movement in the lower back and pelvic area.

Additional Information

This is a diagnostic code used primarily in osteopathic medicine and some physical medicine practices. Treatment typically focuses on manual therapy, exercise, and conservative management approaches.
