The physician's responsibility includes patient preparation, intramuscular injection of the vaccine, post-injection monitoring for adverse reactions, patient education about the vaccine, potential side effects and aftercare instructions.

IMPORTANT Other influenza vaccine codes (e.g., 90630, 90653, 90656, 90673-74, 90682, 90685-88, 90756, Q2035, Q2037, Q2039) may be applicable depending on the specific vaccine administered.Separate codes are available for combination vaccines.
