S37.12XS ICD-10-CM Code: Contusion of ureter, 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 729 — OTHER MALE REPRODUCTIVE SYSTEM DIAGNOSES WITH CC/MCC (MDC 12)
  • MS-DRG 730 — OTHER MALE REPRODUCTIVE SYSTEM DIAGNOSES WITHOUT CC/MCC (MDC 12)
  • MS-DRG 742 — UTERINE AND ADNEXA PROCEDURES FOR NON-MALIGNANCY WITH CC/MCC (MDC 13)

  • MS-DRG 761 — MENSTRUAL AND OTHER FEMALE REPRODUCTIVE SYSTEM DISORDERS WITHOUT CC/MCC (MDC 13)

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.
