K91.3 — Postprocedural intestinal obstruction
K91.3 is a non-billable header ICD-10-CM code for postprocedural intestinal obstruction. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes2 inherited from the categories above K91.3
Also inherited, and the opposite of Excludes1: these conditions are not part of K91.3, 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
Other codes that can never be billed with K91.3
These codes carry an Excludes1 note pointing at K91.3. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K91.3 alone.

Risk adjustment
K91.3 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.

K91.3 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
