Do I need to wait until my current medical malpractice insurance policy expires before I switch insurance companies?

You don’t have to wait.  In most cases, you can start the new policy while your old policy is still in effect, then cancel the old policy for a refund after the new policy is in place.  Your effective date will change, but your retroactive date remains the same, ensuring no gaps in coverage. It’s recommended that a MEDPLI Insurance Broker assist you when you are considering switching companies. See “switching carriers mid-term.”
