K56 — Paralytic ileus and intestinal obstruction without hernia
K56 is a non-billable header ICD-10-CM code for paralytic ileus and intestinal obstruction without hernia. 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.
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.
- stenosis of anus or rectum (K62.4)
Other codes that can never be billed with K56
These codes carry an Excludes1 note pointing at K56. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K56 alone.
Risk adjustment
K56 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 to one of these instead K56
8 child codes. Green means billable.
