I87.011 ICD-10-CM Code: Postthrombotic syndrome with ulcer of right lower extremity
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.

- HCC 383 — Chronic Ulcer of Skin, Except Pressure, Not Specified as Through to Bone or Muscle
