R10.0 vs R10.3
R10.0 (Acute abdomen) compared with R10.3 (Pain localized to other parts of lower abdomen), 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. R10.0 carries an Excludes1 note covering R10.3: “localized abdominal pain (R10.1-R10.3-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
