Can I get a bench warrant if I am hospitalized before and after the assigned court date?

Have your attorney notify the court where you are.

Yes you can, because the Judge wouldn't know about your hospitalization. You should hire a lawyer, who can go to court without you present so a warrant isn't issued.

You could, however, if it is a fact you will be committed, you should inform the court and they can give you a continuance.

Your lawyer will need to explain this, with written confirmation, to the court. If no one appears, a warrant will issue.
