C79.19 ICD-10-CM Code: Secondary malignant neoplasm of other urinary organs
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 656 — KIDNEY AND URETER PROCEDURES FOR NEOPLASM WITH MCC (MDC 11)
- MS-DRG 657 — KIDNEY AND URETER PROCEDURES FOR NEOPLASM WITH CC (MDC 11)
- MS-DRG 658 — KIDNEY AND URETER PROCEDURES FOR NEOPLASM WITHOUT CC/MCC (MDC 11)
- MS-DRG 686 — KIDNEY AND URINARY TRACT NEOPLASMS WITH MCC (MDC 11)
- MS-DRG 687 — KIDNEY AND URINARY TRACT NEOPLASMS WITH CC (MDC 11)
- MS-DRG 688 — KIDNEY AND URINARY TRACT NEOPLASMS WITHOUT CC/MCC (MDC 11)
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 18 — Cancer Metastatic to Bone, Other and Unspecified Metastatic Cancer; Acute Leukemia Except Myeloid (supersedes HCC 19, HCC 20, HCC 21, HCC 22, HCC 23)
Other models: CMS-HCC V22 HCC 8 · RxHCC V08 HCC 18
Risk scores depend on the enrollee's full accepted diagnosis set and segment; a category mapping alone does not determine payment.
