The following are the allowed CVX codes for Influenza immunizations but there are two new vaccines with codes 149 and 150. Since Value sets are determined far ahead of reporting periods and ideally the vaccines administered should only need to be coded once for the patient and coded correctly, I would suggest that coding only that an immunization was administered be sufficient.
Code System Description
111 CVX influenza virus vaccine, live, attenuated, for intranasal use
135 CVX influenza, high dose seasonal, preservative-free
140 CVX Influenza, seasonal, injectable, preservative free
141 CVX Influenza, seasonal, injectable
144 CVX seasonal influenza, intradermal, preservative free
