    I have looked through all my coding books and I cannot locate a mod 33. Do you mean place of service 33? Or mod 32?

    Modifier 33 is a new modifier added by the AMA in December. They have a couple of news letters regarding the definition and usage of the modifier. You can get these from their website. Also there is another thread on the forum for Modfier 33 if you go there you will find the info you seek.
