Influenza codes received a makeover with this year’s CPT update. The codes are no longer classified based on age. The descriptions of these codes now reflect dosage amounts. Codes now state “becomes 0.25 mL dosage” in place of “when administered to children 6-35 months of age” and “becomes 0.5 mL dosage” in place of “when administered to individuals three years and older”. These changes affect codes 90655 – 90661 and 90685 – 90688.nn
