G11.11 is the authoritative medical code for Friedreich ataxia. This classification is used in medical billing and clinical recording to specify the clinical criteria for friedreich ataxia (ICD-10-CM G11.11), ensuring healthcare documentation aligns with current federal coding standards.

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 (FY2026), Appendix B.

  • MS-DRG 058 — MULTIPLE SCLEROSIS AND CEREBELLAR ATAXIA WITH MCC (MDC 01)
  • MS-DRG 059 — MULTIPLE SCLEROSIS AND CEREBELLAR ATAXIA WITH CC (MDC 01)
  • MS-DRG 060 — MULTIPLE SCLEROSIS AND CEREBELLAR ATAXIA WITHOUT CC/MCC (MDC 01)

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.

Code Set: Valid FY2026 and FY2027. FY2026 took effect October 1, 2025.
