N99.5Complications of stoma of urinary tract

N99.5 is the ICD-10-CM diagnosis code for complications of stoma of urinary tract. 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 a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within N99 (intraoperative and postprocedural complications and disorders of genitourinary system, not elsewhere classified), N99.5 is specifically for complications of stoma of urinary tract. Related codes cover postprocedural (acute) (chronic) kidney failure (N99.0), postprocedural urethral stricture (N99.1), postprocedural adhesions of vagina (N99.2), prolapse of vaginal vault after hysterectomy (N99.3), postprocedural pelvic peritoneal adhesions (N99.4), intraoperative hemorrhage and hematoma of a genitourinary system organ or structure complicating a procedure (N99.6), accidental puncture and laceration of a genitourinary system organ or structure during a procedure (N99.7) and other intraoperative and postprocedural complications and disorders of genitourinary system (N99.8).

To report this condition, pick the subcode that matches the documentation: N99.51 (cystostomy), N99.52 (tract) and N99.53 (tract).

The conditions in its Excludes2 note aren't part of N99.5, but may be coded alongside it if the patient has both: mechanical complication of urinary catheter (T83.0-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
