Hello, I work in a medium sized practice, I do Physician billing for clinic billing. I have noticed over the past several months that the doctors have been billing based on time. In there documentation stating "more than 50% of the visit was spent on counseling and/or coordination of care for a total visit of 35 minutes." I guess my question is, can we bill just based on time, or does the documentation also have to reflect the Level of Service also. Meaning billing on time would be a 99214 for an established patient but documentation there is only a 99213. I have not been able to find any real clarification on this, I just want to make sure that I am coding these cases correctly. I could give an example if is needed. Thank you.
