ICD-10/M84.751S

M84.751S ICD-10-CM Code: Incomplete atypical femoral fracture, right leg, 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 559 — AFTERCARE, MUSCULOSKELETAL SYSTEM AND CONNECTIVE TISSUE WITH MCC (MDC 08)
  • MS-DRG 560 — AFTERCARE, MUSCULOSKELETAL SYSTEM AND CONNECTIVE TISSUE WITH CC (MDC 08)
  • MS-DRG 561 — AFTERCARE, MUSCULOSKELETAL SYSTEM AND CONNECTIVE TISSUE WITHOUT CC/MCC (MDC 08)

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 3 MS-DRGs: DRG 559 (MDC 08), DRG 560 (MDC 08), DRG 561 (MDC 08).

From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.
