I am by no means a technical expert on the subject, but I will give the basic information that I have learned by working in numerous pharmacies. Rx "BIN" refers to Bank Identification Number, which basically routes electronic pharmacy insurance claims in the right general direction. Rx "PCN" refers to Processor Control Number, which more specifically directs the electronic pharmacy claims. I'll give a generalized example. When I am setting up my computer system to bill a new insurance, I must first add the BIN, which is a six digit numerical code. There may be many different companies using the same BIN, though; so I then add the PCN to specify exactly how I want the claim to be billed electronically. The PCN does not have a consistent format. I've seen everything from eight digit numerical codes to a single letter and number put together. When someone drops off an insurance card at a pharmacy, these are some of the things for which the technicians will search. Unfortunately, there is no standardization among cards, and not all insurance companies have the decency to print the BIN or PCN on the card. This is why some people have more problems than others when trying to get their insurance cards to work at the pharmacy.
