S10.94XS ICD-10-CM Code: External constriction of unspecified part of neck, sequela
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 604 — TRAUMA TO THE SKIN, SUBCUTANEOUS TISSUE AND BREAST WITH MCC (MDC 09)
- MS-DRG 605 — TRAUMA TO THE SKIN, SUBCUTANEOUS TISSUE AND BREAST WITHOUT MCC (MDC 09)
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.
