N99.6

N99.6 — Intraoperative hemorrhage and hematoma of a genitourinary system organ or structure complicating a procedure

Non-billable headerICD-10-CM

N99.6 is a non-billable header ICD-10-CM code for intraoperative hemorrhage and hematoma of a genitourinary system organ or structure complicating a procedure. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

intraoperative hemorrhage and hematoma of a genitourinary system organ or structure due to accidental puncture or laceration during a procedure (N99.7-)

Excludes2 inherited from the categories above N99.6

Also inherited, and the opposite of Excludes1: these conditions are not part of N99.6, but a patient can have both, so you may code both.

Written on N99 — Intraoperative and postprocedural complications and disorders of genitourinary system, not elsewhere classified

irradiation cystitis (N30.4-)
postoophorectomy osteoporosis with current pathological fracture (M80.8-)
postoophorectomy osteoporosis without current pathological fracture (M81.8)

Risk adjustment

N99.6 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code history

N99.6 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead N99.6
