Administration codes for Hep B and A for medicare

For Hep B I know I have to use G0010 but if Hep A was given the same day, do I do G0010 with 2 units or their is another code to report the adminstration on Hep A. Thank you

re: Administration codes for Hep B and A for medicare

G0008 Administration of influenza virus vaccine
G0009 Administration of pneumococcal vaccine
G0010 Administration of Hepatitis B vaccine

These are the only vaccines covered by Medicare.
Coverage of other vaccines provided as a preventive service may be covered under a patient's Part D coverage.

I am just curious that if Hep A and Hep B administered at the same time (separate vaccination not the combination) will you use G0010 and 90472 or G0010 and 90471 since there is not Gcode for Hep A?
