Question: Our physician administered half dose of flu vaccine instead of a full dose to a child in treatment with chemotherapy for leukemia. The child was asked to return for a second half-dose. Can we bill half the charge and use a 52 modifier?

Answer: Your physician will typically administer half dose of a vaccine in younger children (under the age of three). You have a code specifically created for reporting this service. You’ll report 90655 (Influenza virus vaccine, trivalent, split virus, preservative free, when administered to children 6-35 months of age, for intramuscular use) for this vaccine administration. Your physician will advise a booster to the child after a month or two.
