Doctor used codes 27096x2, 62311 and 77003. He attached a modifier 59 to the 27096. It passed through their edits and was paid. Now they are requested a refund on the 77003. The letter I've received states fluoroscopy included in 27096, which is true. But it isn't included in the 63211. I have searched the internet for information about billing these codes together and have been unsuccessful in finding anything. As these are two separate procedures why are they requesting the refund for the 77003? Are we only allowed payment of 77003 once per day? Before I do request any refunds I want to make sure their reasoning is correct.
