Intraoperative and postprocedural complications and disorders of genitourinary system, not elsewhere classified (N99)

ICD-10 code range N99 covers complications and disorders that arise during or after procedures involving the genitourinary system and are not classified elsewhere. These codes are essential for identifying issues such as kidney failure, urethral strictures, stoma complications, hemorrhage, infections, and accidental injuries linked to genitourinary surgeries or interventions.

This range includes specific codes like N99.0 for acute or chronic postprocedural kidney failure often referred to by terms such as acute kidney injury or postoperative renal impairment. Codes N99.1–N99.12 detail various forms of postprocedural urethral strictures in males and females, including subtypes like meatal, bulbous, and membranous strictures, helping coders accurately classify strictures following catheterization or surgery. Postoperative adhesions and prolapse, such as vaginal vault prolapse after hysterectomy, are captured under N99.2–N99.4. The category also addresses complications of urinary tract stomas (N99.5 to N99.53), detailing hemorrhage, infections, malfunction, herniation, and stenosis. Intraoperative and postprocedural hemorrhage, hematoma, seroma, and accidental punctures affecting genitourinary organs are coded from N99.6 through N99.8. Additional unique codes like N99.83 identify residual ovary syndrome after surgery, while N99.89 covers a broad spectrum of other genitourinary procedure complications, including postoperative urinary incontinence, ureteral kinking, and failed endoscopic procedures. Using these codes ensures precise documentation of surgical complications and related genitourinary disorders for optimal patient care and billing accuracy.
