(Supratrochlear, supraorbital and infraorbital nerve blocks) I was advised to code these with cpt code 64402 facial nerve injection. I would have thought that code 64400 trigeminal nerve injection or any division or branch would better fit this procedure. The reason I was thinking this is that trigeminal nerve has 3 branches and one of the braches is opthalmic this nerve has branches listed and supratrochlear and surpraorgital are listed. I wanted to see if anyone could shead some light on this.. Thanks!
