M51.26 — Annen forskyvning av mellomvirvelskive, lumbalområdet

Discogenic back pain originates from the intervertebral disc itself, often due to internal degeneration or structural failure, such as a displacement of the disc components. This condition may involve the nucleus pulposus pushing through an annular tear.

In cases where the disc displacement is documented as unspecified size, imaging studies such as MRI are still crucial for guiding a diagnostic interpretation.

Herniation in the thoracolumbar region occurs when the disc material extends beyond its normal boundaries between two vertebrae, potentially leading to compression of the spinal nerves and resulting in functional impairment. Unlike other spinal diseases, such as tumors or infections, disc displacement is mechanical and often results from trauma, degeneration, or overuse. Accurate classification in the ICD-10-CM ensures appropriate diagnostic and procedural coding for each patient.
