A54.81 vs G01
A54.81 (Gonococcal meningitis) compared with G01 (Meningitis in bacterial 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. G01 carries an Excludes1 note covering A54.81: “gonococcal (A54.81)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
