CPT® Code 90644

Meningococcal conjugate vaccine, serogroups C & Y and Haemophilus influenzae type b vaccine (Hib-MenCY), 4 dose schedule, when administered to children 6 weeks-18 months of age, for intramuscular use

This CPT® code 90644 refers to a specific combination vaccine designed to protect against meningococcal disease caused by the serogroups C and Y, as well as Haemophilus influenzae type b (Hib). Meningococcal disease is a serious infection caused by the bacterium Neisseria meningitides, which can lead to severe health complications such as septicemia and meningitis. The vaccine is particularly important as it targets two specific serogroups, C and Y, out of the 13 known subtypes of Neisseria meningitides, thereby providing essential immunity against these strains. Additionally, Hib infections can result in various serious conditions, including pneumonia, epiglottitis, and infections of the joints and bones, as well as meningitis. The formulation of this vaccine is specifically intended for children aged 6 weeks to 18 months, ensuring that this vulnerable population receives the necessary protection during a critical period of their immune development. It is important to note that this code pertains solely to the supply of the combination vaccine itself; an additional administration code must be reported for the actual intramuscular injection of the vaccine.
