K50 — Crohn's disease [regional enteritis]
Is K50 billable?
No — K50 is a non-billable header code. K50 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 28 billable codes beneath K50.

Excludes1 — never code together — inherited from K50-K52
The conditions below can never be reported together with K50 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 — inherited from Chapter 11
The conditions below are not part of K50, but a patient may have both at the same time. When documentation supports it, K50 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)
