I have been researching whether or not 99211 and 99213/99214 can be billed together (adding modifier 25). Recently I was told that if a patient comes to see the physician he can bill 99213/99214 then if his/her nurse has to see the patient to administer an injection that is considered a separate service so they suggested billing 99211. I have viewed the CCI edits, Medicare guidelines and cannot locate anything that states the two codes can't be billed together. I disagree with the person who told me this except they have stated to me that she received this information from another source who is billing this way. Any input, suggestions or comments are greatly appreciated.
