ICD-10 Code E84.19 – Cystic fibrosis with other intestinal manifestations (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E84.19 – Cystic fibrosis with other intestinal manifestations
What it is
This code identifies cystic fibrosis when the documented intestinal problem is not one of the more specific listed manifestations. Use it for CF-related bowel involvement when the record supports an intestinal complication but does not name a different CF code.
Clinical signs
Clinical features vary; refer to documentation. CF intestinal involvement may include abdominal pain, constipation, distal intestinal obstruction, or other bowel dysfunction related to thick secretions and impaired digestion.
When to use this code
Use E84.19 when the provider documents cystic fibrosis with an intestinal manifestation that is not captured by a more specific code. It is appropriate when the note clearly links the bowel problem to CF. If the record only says “cystic fibrosis” without intestinal involvement, do not assign this code.
Do not use for
Do not use this code for cystic fibrosis without intestinal manifestations, or when the bowel condition is documented separately and not attributed to CF. Check documentation if another CF complication is specified.
Coding tip
Verify that the intestinal finding is explicitly tied to cystic fibrosis before coding E84.19.
