Use additional code
Report an additional code alongside K90.0 to fully describe the condition. K90.0 is sequenced first.
Code also
Two codes may be needed to describe the condition fully. Whether K90.0 is sequenced first depends on the reason for the encounter.
- exocrine pancreatic insufficiency (K86.81)
Inclusion terms
Alternative wording in documentation that is classified to K90.0.
- Celiac disease with steatorrhea
- Celiac gluten-sensitive enteropathy
- Nontropical sprue
Excludes1 — never code together — inherited from K90
The conditions below can never be reported together with K90.0 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 K90.0, but a patient may have both at the same time. When documentation supports it, K90.0 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 K90.0 existed?
K90.0 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 K90.0?
ICD-10-CM declares these codes mutually exclusive with K90.0 — exactly one of each pair can be correct for a given encounter.
