K57

Header — not billable

Diverticular disease of intestine

The ICD-10 code for diverticular disease of intestine is K57.

K57 is a non-billable header code. It groups related conditions but cannot be used on its own for reimbursement — select one of the 8 more specific codes below.

Clinical notes

Code also

Two codes may be needed to fully describe a condition, but unlike Code First/Use Additional Code, the sequencing order is not mandated by convention.

if applicable peritonitis K65.-

Excludes1 (not coded here)

An Excludes1 note is a pure exclusion: the excluded condition and this code should never be reported together, because the two conditions cannot occur at the same time (e.g. a congenital form vs. an acquired form of the same disease).

congenital diverticulum of intestine (Q43.8)
Meckel's diverticulum (Q43.0)

Excludes2 (not included here)

An Excludes2 note means the excluded condition is not part of this one, but a patient can have both at the same time — in that case both codes may be reported together.

diverticulum of appendix (K38.2)
