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 are problems with how the bones, joints, and muscles in your lower back (lumbar spine) move and work together. 'Segmental' refers to individual spine segments not moving properly, while 'somatic' refers to problems with the body's structural components like muscles, bones, and connective tissues. This can cause pain, stiffness, and reduced mobility in the lower back area.

Additional Information

This is a functional diagnosis often used in osteopathic and chiropractic medicine to describe mechanical problems in spinal movement rather than structural damage. Treatment typically focuses on restoring normal movement and function.
