About N99.89
N99.89 is the ICD-10-CM diagnosis code for other postprocedural complications and disorders of genitourinary system. It belongs to category N99 (intraoperative and postprocedural complications and disorders of genitourinary system, not elsewhere classified), block N99 (intraoperative and postprocedural complications and disorders of genitourinary system, not elsewhere classified) and chapter 14 (diseases of the genitourinary system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within N99.8, choose N99.89 (Other postprocedural complications and disorders of genitourinary system) only when documentation doesn't support a more specific option: other intraoperative complications of genitourinary system (N99.81), postprocedural hemorrhage of a genitourinary system organ or structure following a procedure (N99.82), residual ovary syndrome (N99.83), postprocedural hematoma and seroma of a genitourinary system organ or structure following a procedure (N99.84), post endometrial ablation syndrome (N99.85) and intraoperative and postprocedural complications and disorders of breast (N99.86).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 698 (Other Kidney and Urinary Tract Diagnoses with MCC, relative weight 1.6398), DRG 699 (Other Kidney and Urinary Tract Diagnoses with CC, relative weight 1.0003), DRG 700 (Other Kidney and Urinary Tract Diagnoses without CC/MCC, relative weight 0.6741), DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 997.5 (urinary complications, not elsewhere classified).
