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

Not part of this code, but both may be coded when both are present.

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-)
