How an health insurance company works and which departments are present in a Health insurance company ?

and i also want to know the internal procedure goes in health insurance company after a customer takes a policy ?
--------------------
It's not a mystery. The departments are reflections of their actions, just like any other company. Insurance companies try to attract customers, so they have a marketing department. Insurance companies collect premiums and pay out claims. So they have a billing department and a claims department. They have to set premiums so they have an actuarial department. They have to service their business so they have a Customer Service department. They have to service their producers so they have a Producer Services department. It's all pretty intuitive.
