I need some help clarifying codes 64490-64495 (new facet joint block code as of 1/1/10)...we are under the impression that you can only be reimbursed up to a maximum of three per day per patient, unless performed bilaterally. If billed with modifier 50 then they will be reimbursed at the number of levels you would perform and you can bill out multiple levels then. I'm confused though since I have always used RT & LT modifiers to Medicare and most payers unless they specify they want 50 to be used. Need help as I'm thinking this is just physician specific and not applied to ASC's. Has anyone else run into this issue and if so, can you assist me?

Thank you desperately!
