K57: Diverticular disease of intestine
Non-billable headerICD-10-CM
K57 is a non-billable header ICD-10-CM code for diverticular disease of intestine. 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.
- diverticulum of appendix (K38.2)
Code also
Both codes may be needed to describe the encounter fully. Sequencing depends on the reason for the visit.
- if applicable:
- pelvic abscess (K6A.0-)
- peritonitis (K65.-)
