Agree, the pre, intra and post service work of the injections does not include labs.
Are you billing for a pro-fee/physician office?
When are the labs being ordered? If the provider saw the patient for an office E/M and ordered the labs at that time, they got credit for the lab orders at that visit.
If you are talking about Prolia, if that is being administered once every six months, when is the provider seeing the patient?
If you are talking about Zoledronic Acid, depending on why and if it is the once a year via IV, the provider would have seen the patient and ordered the labs at the E/M visit, correct?
Can you elaborate more on the scenario?
ACR may have helpful billing/coding info if you need help:
