Guys, could you recommend a reputed health insurance plan I could go for today - which will hold up for next 30-40 years?

ICICI Lombard? Have been using them for many years now.

@loud-glass-33663 ever had to claim it? How's the process?

Not my policy. My wife had ICICI Lombard and I had a different policy (through employer) when we had my first child. Claimed for maternity benefit - it was seamless. Just a call and cashless went through - no sub limits. Actually, my own policy (through a TPA) caused a lot of headaches to claim the balance (you can claim 2 policies) - they demanded original copies of bills, etc. which ICICI went to great lengths to have a notarised copy sent to my house on a Sunday (they didn’t need to). So then, I got our TPA ditched, switched to ICICI and have a policy from them since then personally as well.

i have max bupa , got cashless claim with breeze and had good experience with them better is lookout for hospital in your city which has cashless tieups with insurance providers and take decision on that basis
