Hey dude. check with Atena. One of my fren had a surgery and that almost cost 25 k, but he paid just 100 dolor since insurance covered all the expenses. and off course he had an insurance from atena, but make sure that when the insurance policy get effected. coz most of the insurence policy has some time crietria  like the police will get effective only after a year since insurance has established. so check with the insurance policy, and they have different kind of plan for insurance policy so check with all different plan. if u need to do surgery withing 6 month like that, get a better plan and i think its bit expensive. so try to talk with the clerk in the insurance company.
