A88 vs G14
A88 (Other viral infections of central nervous system, not elsewhere classified) compared with G14 (Postpolio syndrome), 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. A88 carries an Excludes1 note covering G14: “postpolio syndrome (G14)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
