Okay, so you know how when we play games with our friends, we need to follow some rules so that everyone can have fun and play together fairly? Well, when big companies like banks and other healthcare companies work together, they also need some rules so that everyone can work together safely and fairly. These rules are called the "General Code of Operating Rules" or GCOR for short.
GCOR is a set of rules that all these companies agree to follow when they work together to move things around safely. For example, when trains move around the country, different companies need to work together to make sure that the tracks are safe and the trains don't run into each other.
To make sure that everyone follows these rules, there are people called "inspectors" who check to make sure that everyone is playing by the rules. Just like how moms and dads might check to make sure we follow the rules when we play games with our friends.
So, the General Code of Operating Rules is like a big rulebook that everyone needs to follow when they work together to move things around. Following these rules makes sure that everything runs smoothly and safely for everyone involved.
