S99.191S ICD-10-CM Code: Other physeal fracture of right metatarsal, 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 913 — TRAUMATIC INJURY WITH MCC (MDC 21)
  • MS-DRG 914 — TRAUMATIC INJURY WITHOUT MCC (MDC 21)

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.
