G02 vs G05
G02 (Meningitis in other infectious and parasitic diseases classified elsewhere) compared with G05 (Encephalitis, myelitis and encephalomyelitis 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. G02 carries an Excludes1 note covering G05: “meningoencephalitis and meningomyelitis in other infectious and parasitic diseases classified elsewhere (G05)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
