I have a handout from one of my insurers that says the following as an example:
MMR 90460
DTaP
Pneumo 90461 x 2
another visit...
RV 90460
DTAP-Hib-IPV 90461 x 1
It looks like they only want to pay for 1 unit of 90461 with each additional SHOT, but I thought it was originally for each add component.
