K91.6

K91.6Intraoperative hemorrhage and hematoma of a digestive system organ or structure complicating a procedure

Non-billable headerICD-10-CM

K91.6 is a non-billable header ICD-10-CM code for intraoperative hemorrhage and hematoma of a digestive 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 digestive system organ or structure due to accidental puncture and laceration during a procedure (K91.7-)

Excludes2 inherited from the categories above K91.6

Also inherited, and the opposite of Excludes1: these conditions are not part of K91.6, but a patient can have both, so you may code both.

Written on K91 Intraoperative and postprocedural complications and disorders of digestive system, not elsewhere classified

  • complications of artificial opening of digestive system (K94.-)
  • complications of bariatric procedures (K95.-)
  • gastrojejunal ulcer (K28.-)
  • postprocedural (radiation) retroperitoneal abscess (K68.11)
  • radiation colitis (K52.0)
  • radiation gastroenteritis (K52.0)
  • radiation proctitis (K62.7)

Risk adjustment

K91.6 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

K91.6 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 K91.6
