About M51.369

M51.369 is the ICD-10-CM diagnosis code for other intervertebral disc degeneration, lumbar region without mention of lumbar back pain or lower extremity pain. 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 billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within M51.36, choose M51.369 (without mention of lumbar back pain or lower extremity pain) only when documentation doesn't support a more specific option: with discogenic back pain only (M51.360), with lower extremity pain only (M51.361) and with discogenic back pain and lower extremity pain (M51.362).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 551 (Medical Back Problems with MCC, relative weight 1.6358) and DRG 552 (Medical Back Problems without MCC, relative weight 0.9584), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It was added in FY2025, effective October 1, 2024.
