M9902 - Dysfunction of spinal joints and muscles in the chest/upper back area

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 problems with how the spine moves and functions in the thoracic region (the middle part of your back, roughly from your shoulders to the bottom of your ribcage). 'Segmental dysfunction' refers to problems with individual spinal segments not moving properly, while 'somatic dysfunction' involves issues with the muscles, joints, and connective tissues in this area. This can cause pain, stiffness, or restricted movement in the upper back and chest region.

Additional Information

This is primarily an osteopathic medicine diagnosis used to describe functional problems with spinal movement rather than structural damage. Treatment typically focuses on manual therapy techniques to restore normal function.
