ICD-10/I70.92

I70.92 ICD-10-CM Code: Chronic total occlusion of artery of the extremities

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 299 — PERIPHERAL VASCULAR DISORDERS WITH MCC (MDC 05)
  • MS-DRG 300 — PERIPHERAL VASCULAR DISORDERS WITH CC (MDC 05)
  • MS-DRG 301 — PERIPHERAL VASCULAR DISORDERS WITHOUT CC/MCC (MDC 05)

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.
