K90 — Intestinal malabsorption
Is K90 billable?
No — K90 is a non-billable header code. K90 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 13 billable codes beneath K90.

Excludes1 — never code together
The conditions below can never be reported together with K90 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- intestinal malabsorption following gastrointestinal surgery (K91.2)
Excludes2 — not included here — inherited from Chapter 11
The conditions below are not part of K90, but a patient may have both at the same time. When documentation supports it, K90 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)
