S37.63XA ICD-10-CM Code: Laceration of uterus, initial encounter
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 742 — UTERINE AND ADNEXA PROCEDURES FOR NON-MALIGNANCY WITH CC/MCC (MDC 13)
- MS-DRG 743 — UTERINE AND ADNEXA PROCEDURES FOR NON-MALIGNANCY WITHOUT CC/MCC (MDC 13)
- MS-DRG 760 — MENSTRUAL AND OTHER FEMALE REPRODUCTIVE SYSTEM DISORDERS WITH CC/MCC (MDC 13)
- MS-DRG 761 — MENSTRUAL AND OTHER FEMALE REPRODUCTIVE SYSTEM DISORDERS WITHOUT CC/MCC (MDC 13)
- MS-DRG 963 — OTHER MULTIPLE SIGNIFICANT TRAUMA WITH MCC (MDC 24)
- MS-DRG 964 — OTHER MULTIPLE SIGNIFICANT TRAUMA WITH CC (MDC 24)
- MS-DRG 965 — OTHER MULTIPLE SIGNIFICANT TRAUMA WITHOUT CC/MCC (MDC 24)
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.

Potential MS-DRG Relationships (FY2026)
CC — Complication or Comorbidity. Reported as a secondary diagnosis, this code raises the stay's MS-DRG severity tier — except when the principal diagnosis is one of 203 clinically related codes on its CMS exclusion list. Does not count toward severity when the stay groups to DRGs 957-959 (Other O.R. Procedures for Multiple Significant Trauma); DRGs 963-965 (Other Multiple Significant Trauma).
Named in the grouper logic of 7 MS-DRGs: DRG 742 (MDC 13), DRG 743 (MDC 13), DRG 760 (MDC 13), DRG 761 (MDC 13), DRG 963 (MDC 24), DRG 964 (MDC 24), DRG 965 (MDC 24).
From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.
