B43.1 vs G07
B43.1 (Pheomycotic brain abscess) compared with G07 (Intracranial and intraspinal abscess and granuloma in diseases classified elsewhere), 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. G07 carries an Excludes1 note covering B43.1: “chromomycotic (B43.1)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
