C30.0 vs C72.2
C30.0 (Malignant neoplasm of nasal cavity) compared with C72.2 (Malignant neoplasm of olfactory nerve), 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. C30.0 carries an Excludes1 note covering C72.2: “malignant neoplasm of olfactory bulb (C72.2-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
