Actually, in my opinion, most billers do not do coding. We do seem to get several coding questions. It is good to know some coding, but I don't code for my providers. I will assist them if they are unsure what they should be coding by pointing them to possible codes but it must be their decision on the final codes. I am not a certified coder and I don't have the patient's chart in front of me, and I wasn't in the room. If I did coding it would be a separate service from the billing.
