How do I make a manufacturer savings card actually apply at the pharmacy?
Ask the pharmacist to run it as secondary insurance with COB Code 03.
Say this to the pharmacist, word for word: “Please process the manufacturer savings card as secondary insurance with Coordination of Benefits (COB) Code 03.”
That is the instruction that makes the system stack the card on top of your existing coverage instead of rejecting it. It can take a co-pay from hundreds down to something manageable.
