International Classification of Diseases

Last updated: 4/10/2026

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 movement or positioning of the ribs and related muscles, joints, or connective tissues in the chest area. Segmental and somatic dysfunction refers to problems with how the spine segments and body structures move and function together. In the rib cage area, this can cause restricted movement, muscle tension, or misalignment that may lead to pain, stiffness, or breathing difficulties. This condition is commonly treated with chiropractic care or osteopathic manipulative treatment to restore normal movement and function.

Additional Information

This is a non-billable parent code that requires additional specificity for proper billing. Treatment typically involves manual therapy techniques to restore normal rib cage movement and function.
