What is the ruling on a female doctor sending medical reports to insurance companies for approval of examinations and operations?

If the insurance system in the hospital is based on cooperative (takaful) insurance, then there is no objection to working with it. However, if it is a forbidden commercial insurance, then the female doctor's work in the insurance department and her correspondence with the insurance company to obtain the insurance amount is considered aiding in sin and aggression, which is impermissible, due to His (Allah's) saying: "And do not cooperate in sin and aggression."
