I08 vs Q22

I08 (Multiple valve diseases) compared with Q22 (Congenital malformations of pulmonary and tricuspid valves), from the official CMS tabular data. Both may be reported when both conditions are documented (Excludes2).

Can these codes be reported together?

Excludes2 marks distinct conditions — both may be reported when both are documented.
