What is the code for giving omalizumab in the office?
Omalizumab (Xolair) is given by subcutaneous injection. The applicable code is 90772 (renumbered 96372 for 2009) Therapeutic, prophylactic or diagnostic injection (specify substance or drug); subcutaneous or intramuscular. Also code J2357 for the agent, per 5 mg. Some have argued that the work of preparation and the risk of the injection justify use of the chemotherapy code for subcutaneous injection, 96401, but this has not yet been approved by CMS or AMA.
