F03 vs G30
F03 (Unspecified dementia) compared with G30 (Alzheimer's disease), 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. G30 carries an Excludes1 note covering F03: “senile dementia NOS (F03.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
