E84.11 vs Q41
E84.11 (Meconium ileus in cystic fibrosis) compared with Q41 (Congenital absence, atresia and stenosis of small intestine), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. Q41 carries an Excludes1 note covering E84.11: “cystic fibrosis with intestinal manifestation (E84.11)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
