Intraoperative and postprocedural complications and disorders of genitourinary system, not elsewhere classified (N99)
The ICD-10 code section N99 is used to classify intraoperative and postprocedural complications and disorders of the genitourinary system that are not classified elsewhere. This includes complications arising during or after procedures involving the urinary tract and reproductive organs.
This section covers a variety of specific complications, such as postprocedural kidney failure (N99.0), which includes acute kidney injury following procedures, sometimes called postoperative renal impairment. It also details multiple types of postprocedural urethral strictures (N99.1 series) ; narrowed sections of the urethra after surgery, with subcodes for male and female strictures and exact locations like meatal or bulbous urethral stricture. Additional codes address adhesions and prolapses post-hysterectomy (N99.2, N99.3), as well as complications related to urinary stomas, such as infections, hemorrhage, or malfunction (N99.5 series). Intraoperative hemorrhages and accidental punctures during genitourinary procedures are captured by codes N99.6 and N99.7. The section also includes other less common but significant disorders like post endometrial ablation syndrome (N99.85) and residual ovary syndrome (N99.83).
Medical coders searching for the ICD-10 code for urinary complications following surgery, such as post-catheterization urethral stricture or hemorrhage after cystostomy, will find these codes essential for capturing specific genitourinary procedural complications. Using the synonyms provided (e.g., postoperative urethral stricture, ovarian remnant syndrome, cystostomy hemorrhage) helps ensure accurate coding and clarity when documenting genitourinary system complications not classified elsewhere.

Instructional Notations
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.

- postoophorectomy osteoporosis with current pathological fracture M80.8
- postoophorectomy osteoporosis without current pathological fracture M81.8
Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Anuria
Absence of urine formation. It is usually associated with complete bilateral ureteral (URETER) obstruction, complete lower urinary tract obstruction, or unilateral ureteral obstruction when a solitary kidney is present.
Oliguria
Decreased URINE output that is below the normal range. Oliguria can be defined as urine output of less than or equal to 0.5 or 1 ml/kg/hr depending on the age.
Ureter
One of a pair of thick-walled tubes that transports urine from the KIDNEY PELVIS to the URINARY BLADDER.
Urine
Liquid by-product of excretion produced in the kidneys, temporarily stored in the bladder until discharge through the URETHRA.
