K56.6 — Other and unspecified intestinal obstruction
K56.6 is a non-billable header ICD-10-CM code for other and unspecified intestinal obstruction. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes1 inherited from the categories above K56.6
These are not written on K56.6, but they bind it: a note on a category applies to every code beneath it. Billing K56.6 with anything listed here is a denial.
Written on K56 — Paralytic ileus and intestinal obstruction without hernia
Excludes2 inherited from the categories above K56.6
Also inherited, and the opposite of Excludes1: these conditions are not part of K56.6, but a patient can have both, so you may code both.
Other codes that can never be billed with K56.6
These codes carry an Excludes1 note pointing at K56.6. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K56.6 alone.
Risk adjustment
K56.6 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
K56.6 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
