I80.253 ICD-10-CM Code: Phlebitis and thrombophlebitis of calf muscular vein, bilateral
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 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)
- MS-DRG 791 — PREMATURITY WITH MAJOR PROBLEMS (MDC 15)
- MS-DRG 793 — FULL TERM NEONATE WITH MAJOR PROBLEMS (MDC 15)
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.
Risk Adjustment (CMS-HCC)
Payment categories this diagnosis maps to under CMS-HCC V28, payment year 2026.
- HCC 267 — Deep Vein Thrombosis and Pulmonary Embolism
Other models: CMS-HCC V22 HCC 108 · RxHCC V08 HCC 215
Risk scores depend on the enrollee's full accepted diagnosis set and segment; a category mapping alone does not determine payment.
