C17.3 vs Q43.0
C17.3 (Meckel's diverticulum, malignant) compared with Q43.0 (Meckel's diverticulum (displaced) (hypertrophic)), 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. C17.3 carries an Excludes1 note covering Q43.0: “Meckel's diverticulum, congenital (Q43.0)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
