M51.36Other intervertebral disc degeneration, lumbar region

M51.36 is the ICD-10-CM diagnosis code for other intervertebral disc degeneration, lumbar region. It belongs to category M51 (thoracic, thoracolumbar, and lumbosacral intervertebral disc disorders), block M50-M54 (other dorsopathies) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within M51.3 (other thoracic, thoracolumbar and lumbosacral intervertebral disc degeneration), M51.36 is specifically for other intervertebral disc degeneration, lumbar region. Related codes cover thoracic region (M51.34), thoracolumbar region (M51.35) and lumbosacral region (M51.37).

To report this condition, pick the subcode that matches the documentation: M51.360 (with discogenic back pain only), M51.361 (with lower extremity pain only), M51.362 (with discogenic back pain and lower extremity pain) and M51.369 (without mention of lumbar back pain or lower extremity pain).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2025 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 722.52 (degeneration of lumbar or lumbosacral intervertebral disc).
