I recently starting working for an FQHC facility and have been doing some research on how to properly bill/code for our facility. We have a lot of patients who will see a provider one day, then the following day come back JUST for a blood draw. From what I have been reading, the reimbursement we receive for the initial provider visit is an all inclusive rate which includes payment for the NV for just the blood draw. Some articles I have read, say we can code 36415 on the previous encounter with the provider or the following visit with the provider. Is that true? If so, what documentation is needed? Example, specifying date of actual blood draw.
