Gall bladder removal costs

Hi guys recently my mother had sevear abdomen pain and after doing ctce scan,gallstones have been detected. Today I checked with two doctors at Care hopsital , Dr ravinder reddy & Dr PBS satyanarayana raju.. both told that the gall bladder have to removed with laposcopy and if there is any stones that have entered Common duct then that have to be removed first by andoscopy.. both costing around 1L & 60k... now I do have insurance which covers upto 3L provided by my company but then I would like to know the common pricing for these surgeries... have anyone done the same in hyderabad pls share your experience and insurance claim /expense s... I feel they are may anyhow try to bill upto 3L or maybe more with all that medicine, room stay and all charges... so if there is another hospital which can do same surgeries at lesser price I might have a look at it
