I opted for the Health Infinity plan for my parents. The digital onboarding was incredibly fast with no medical tests required since they are under 50. We had a minor daycare procedure last month, and the cashless approval came through in less than 2 hours. Very impressed with the efficiency.

The Bajaj Finance Health app is a lifesaver. I use it for my regular OPD consultations and medicine orders. The 10% discount on pharmacy bills and the easy reimbursement for doctor visits make it much more than just a 'hospitalization' policy. It’s daily health support.

Switched my family floater to Bajaj General this year. The network of hospitals in my city (Pune) is excellent. The only downside was a slight delay in getting my physical card, but the digital copy on the app works everywhere. The 'Wellness Rewards' for hitting step goals is a cool touch!
