I would advise to go for Max Bupa, I had taken Max Bupa Health Insurance for my family (Me and my wife) and had to go for surgery for kidney stone immediately after 2 months. I was overwhelmed by the quick response from the claim team, I was hospitalized in Max Balaji Hospital.
I got the cashless approval within 4-5 hours also as this was day care surgery which no other insurance company cover for first 2-3 years..i got the reimbursement for Post hospitalization expenses within 10-12 days also post filing the claim..God bless you Guys.!
