M50.820Other cervical disc disorders, mid-cervical region, unspecified level

M50.820 is the ICD-10-CM diagnosis code for other cervical disc disorders, mid-cervical region, unspecified level. It belongs to category M50 (cervical 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 M50.82, choose M50.820 (unspecified level) only when documentation doesn't support a more specific option: disorders at C4-C5 level (M50.821), disorders at C5-C6 level (M50.822) and disorders at C6-C7 level (M50.823).

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 FY2017, effective October 1, 2016.

Before ICD-10, this condition was coded in ICD-9-CM as 722.91 (other and unspecified disc disorder, cervical region).
