I too have been trying to find more concrete information on this issue as well. I am a coder in an ENT office, but get this injection from my allergist in a different office. It bothers me quite a lot that I am being billed for a chemo code (yes, I do understand the description).
Here is a exerpt from SuperCoder that I found - regarding administering the Xolair (published Aug 2010, Pulmonology Coding Alert):
"Since the physician office doesn't incur the cost of the drug, the physician/practice should not be reimbursed for this. On the other hand, the administration of the drug does represent an expense to the physicain (for the office, ataff and equipment), and therefore, you can report it.
Red Flag
There has been much controversy over the correct code to select for Xolair administration. Athough catagorized as monoclonal antibody (which would lend toward reporting 96401.
Chemotherapy administration, subcutaneous or intramuscular; non-0hormal andi-neoplastic)., most payers require reporting 96372 (
Therapeutic, prophylactic, or diagnostic injection- specify the substance or drug - ; subcutaneous or intra muscular)
due to the fact that the use of Xolair isn not anti-neoplasticin nature.Without specific instruction allowing the physician to bill 96401 for Xolair administration, the more appropriate code to report is 96732"
If others have any other supporting info that is more recent, I would love to see it.
