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 173 — ULTRASOUND ACCELERATED AND OTHER THROMBOLYSIS WITH PRINCIPAL DIAGNOSIS PULMONARY EMBOLISM (MDC 04)
- MS-DRG 175 — PULMONARY EMBOLISM WITH MCC OR ACUTE COR PULMONALE (MDC 04)
- MS-DRG 176 — PULMONARY EMBOLISM WITHOUT MCC (MDC 04)
- 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.

Other models: CMS-HCC V22 HCC 107 · CMS-HCC V22 HCC 85 · RxHCC V08 HCC 186 · 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.
Code Set: Valid FY2026 and FY2027. FY2026 took effect October 1, 2025.
