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 698 — OTHER KIDNEY AND URINARY TRACT DIAGNOSES WITH MCC (MDC 11)
MS-DRG 699 — OTHER KIDNEY AND URINARY TRACT DIAGNOSES WITH CC (MDC 11)
MS-DRG 700 — OTHER KIDNEY AND URINARY TRACT DIAGNOSES WITHOUT CC/MCC (MDC 11)
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.
