Other intervertebral disc degeneration, thoracolumbar region

This code signifies age-related or pathological deterioration of the intervertebral discs within the thoracolumbar spine, excluding disc displacement or herniation. It represents a degenerative process affecting the structural integrity and function of the discs in the thoracic and lumbar regions.

Apply this code when documentation specifies intervertebral disc degeneration in the thoracolumbar region without evidence of disc herniation or displacement. This is appropriate for conditions like degenerative disc disease affecting both thoracic and lumbar segments, or when the specific segment (thoracic vs. lumbar) is not precisely documented but the involvement spans both.

• Ensure documentation clearly states "degeneration" and specifies the "thoracolumbar region" or implies involvement of both thoracic and lumbar segments.
• Do not use this code if disc displacement (e.g., herniation, protrusion) is documented; instead, refer to codes within M51.2-.
• If the degeneration is localized to either the thoracic (M51.34) or lumbar (M51.36) region only, use the more specific code.
