ONS coding system

Okay kiddo, so you know when we talk about things, we give them names, right? Like when we talk about different types of toys, we might call one a car and another a doll. Well, when grown-ups need to talk about different types of illnesses or injuries that people can have, they also use names. These names are called codes.

Now, ONs coding system is a way for grown-ups who work in hospitals or doctor's offices or other places where people go to get help with their health to keep track of all the different codes for different illnesses, injuries, and treatments. It's like a big list that they can use to look up the code for whatever they're talking about.

And why is this important, you might ask? Well, it helps them make sure they're all talking about the same thing and helps them keep track of all the different types of things they see. Plus, if they need to share information with other hospitals or doctors, they need to use the same codes so everyone understands what they're talking about.

So there you have it, ONs coding system is just a way for grown-ups to keep track of all the codes they use to talk about different health problems and treatments.
