A92.0 vs A98
A92.0 (Chikungunya virus disease) compared with A98 (Other viral hemorrhagic fevers, not elsewhere classified), 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. A98 carries an Excludes1 note covering A92.0: “chikungunya hemorrhagic fever (A92.0)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
