It is safe to get a health insurance for medical practitioners in the cases of illness, injury or if anything wrong happen by you to a patient. But there is a chance for the health insurance company to cancel your insurance due to many cases.
They will never look to retroactively cancel your health insurance, unless they have been defrauded in some way like false or incomplete information regarding your medical history or by in any other way of means.
In some cases like as you are honest in your service but due to some malpractice there is a chance of cancellation of your insurance.
Following the insurance company rules, one can get out of the problem. Get a piece of mind for your practice at "Baxtermalpracticeinsurance"
