S82.61XB ICD-10-CM Code: Displaced fracture of lateral malleolus of right fibula, initial encounter for open fracture type I or II

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 562 — FRACTURE, SPRAIN, STRAIN AND DISLOCATION EXCEPT FEMUR, HIP, PELVIS AND THIGH WITH MCC (MDC 08)
  • MS-DRG 563 — FRACTURE, SPRAIN, STRAIN AND DISLOCATION EXCEPT FEMUR, HIP, PELVIS AND THIGH WITHOUT MCC (MDC 08)
  • 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.

Official Registry Overview & Definition

Displaced fracture of lateral malleolus of right fibula, initial encounter for open fracture type I or II is a billable ICD-10-CM diagnosis code (S82.61B).

Official Tabular Instructional Notes
