M50.122 ICD-10-CM Code: Cervical disc disorder at C5-C6 level with radiculopathy
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.
