When are labs coded. For example, in profee coding for a well child visit, would you code 83655 and 85018 if they are done? I’m not talking about actual blood draws, but the actual labs performed on blood samples. I thought labs were only coded with a certain modifier and only if they were sent to outside facility (so the provider gets paid for transportation charges). Otherwise if they were performed by an internal lab, I thought the provider skipped coding them and the internal lab coded them? Can someone please summarize when to code labs for me? For profee and other kinds of coding too? Thanks!!
