Yes, that's how I read it too. From the OP:

"When performing say a Kruskal Wallis test, I don't want to consider
such patients [i.e., those labeled as "Either 1 or 2"] as a separate group."

I don't think we've been told what the outcome variable is. Nor have we
been told why the OP wants to use the KW test. It would not surprise me
at all if ANOVA was preferable to KW.
