ICD-10/M50.320

M50.320 ICD-10-CM Code: Other cervical disc degeneration, mid-cervical region, unspecified level

Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.

Inpatient Payment Groups (MS-DRG)

MS-DRGs this diagnosis helps define, as principal or secondary, per the CMS ICD-10-CM/PCS MS-DRG Definitions Manual v43.0, Appendix B.

  • MS-DRG 551 — MEDICAL BACK PROBLEMS WITH MCC (MDC 08)
  • MS-DRG 552 — MEDICAL BACK PROBLEMS WITHOUT MCC (MDC 08)

A diagnosis appearing in a group's logic does not by itself determine the DRG assigned to a stay; the grouper uses the full claim.
