M51.3: Other specified intervertebral disc degeneration

Intervertebral discs consist of cartilage and connective tissue. Intervertebral discs connect neighboring vertebrae to one another and absorb pressure and shocks. An intervertebral disc consists of a firm ring with a soft core.

One symptom of worn discs is back pain, for example. The pain may also spread to the arms or legs.
