S99.041S ICD-10-CM Code: Salter-Harris Type IV physeal fracture of right calcaneus, 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.

Potential MS-DRG Relationships (FY2026)
Not on the CMS CC/MCC list — as a secondary diagnosis this code does not change MS-DRG severity.
Named in the grouper logic of 2 MS-DRGs: DRG 913 (MDC 21), DRG 914 (MDC 21).
From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.
