anybody can explain or help me how to bill 26 and TC in facility setting. our physicians renting an office in hospital, our physicians own the machine and does the reading and interpretation at the same time ex:92135 and 92136, we simply billed as 92135 and 92136, guess what we got denied by medicare as CO109- claim not cover by this payor... should we bill line item like 92135-26 on first line and 92135-TC on second line? thank you
