I50.814 ICD-10-CM Code: Right heart failure due to left heart failure

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 291 — HEART FAILURE AND SHOCK WITH MCC (MDC 05)
  • MS-DRG 292 — HEART FAILURE AND SHOCK WITH CC (MDC 05)
  • MS-DRG 293 — HEART FAILURE AND SHOCK 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 226 — Heart Failure, Except End-Stage and Acute (supersedes HCC 227)

Other models: CMS-HCC V22 HCC 85 · RxHCC V08 HCC 186

Risk scores depend on the enrollee's full accepted diagnosis set and segment; a category mapping alone does not determine payment.

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