D49.519 ICD-10-CM Code: Neoplasm of unspecified behavior of unspecified kidney

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 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.

Potential MS-DRG Relationships (FY2026)

Not on the CMS CC/MCC list — as a secondary diagnosis this code does not change MS-DRG severity.

Named in the grouper logic of 6 MS-DRGs: DRG 656 (MDC 11), DRG 657 (MDC 11), DRG 658 (MDC 11), DRG 686 (MDC 11), DRG 687 (MDC 11), DRG 688 (MDC 11).

From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.

Clinical classification (AHRQ CCSR):NEO072 — Neoplasms of unspecified nature or uncertain behavior (default).
