About N99.820

N99.820 is the ICD-10-CM diagnosis code for postprocedural hemorrhage of a genitourinary system organ or structure following a genitourinary system procedure. 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 N99.82 (postprocedural hemorrhage of a genitourinary system organ or structure following a procedure), N99.820 is specifically for postprocedural hemorrhage of a genitourinary system organ or structure following a genitourinary system procedure. Related codes cover other procedure (N99.821).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 919 (Complications of Treatment with MCC, relative weight 1.763), DRG 920 (Complications of Treatment with CC, relative weight 0.9975) and DRG 921 (Complications of Treatment without CC/MCC, relative weight 0.6722), in MDC 21 (Injuries, Poisonings and Toxic Effects of Drugs), 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 changed in FY2017 (title revised).

Before ICD-10, this condition was coded in ICD-9-CM as 998.11 (hemorrhage complicating a procedure).
