K91
K91 — Intraoperative and postprocedural complications and disorders of digestive system, not elsewhere classified
Non-billable headerICD-10-CM
K91 is a non-billable header ICD-10-CM code for intraoperative and postprocedural complications and disorders of digestive system, not elsewhere classified. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
Other codes that can never be billed with K91
These codes carry an Excludes1 note pointing at K91. 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 alone.
Risk adjustment
K91 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.
