K57 — Diverticular disease of intestine
Is K57 billable?
No — K57 is a non-billable header code. K57 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 24 billable codes beneath K57.

Excludes1 — never code together
The conditions below can never be reported together with K57 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here
The conditions below are not part of K57, but a patient may have both at the same time. When documentation supports it, K57 and the excluded code may both be reported.
- diverticulum of appendix (K38.2)
Code also
Two codes may be needed to describe the condition fully. Whether K57 is sequenced first depends on the reason for the encounter.
Excludes2 — not included here — inherited from Chapter 11
The conditions below are not part of K57, but a patient may have both at the same time. When documentation supports it, K57 and the excluded code may both be reported.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)

How long has K57 existed?
K57 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
Which codes are confused with K57?
ICD-10-CM declares these codes mutually exclusive with K57 — exactly one of each pair can be correct for a given encounter.
