Intraoperative and postprocedural complications and disorders of genitourinary system, not elsewhere classified (N99) ICD-10-CM
The N99 code range covers intraoperative and postprocedural complications and disorders of genitourinary system, not elsewhere classified with 57 ICD-10-CM diagnosis codes. 44 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the N99 Code Range
These complications occur during or after procedures involving the urinary or reproductive system. The category also includes breast complications.
N99.0 describes kidney failure after a procedure. N99.1 groups urethral strictures, or narrowing of the urethra, by sex and, for males, by site. N99.2 through N99.4 describe vaginal and pelvic adhesions, where tissue sticks together, and vaginal vault prolapse after hysterectomy.
N99.5 separates urinary stoma complications by stoma type and problem, such as bleeding, infection or malfunction. N99.6 and N99.7 distinguish bleeding from accidental puncture during procedures, then separate genitourinary procedures from other procedures. N99.8 groups other complications, including those involving the ovary, endometrium and breast.
FY 2027 changes: The FY 2027 ICD-10-CM update, effective October 1, 2026, added N99.860 and N99.861.
