How do you buy a health insurance plan? If you just settle with the plan your agent sells or are happy knowing you have bought the cheapest plan, there is a bit of unlearning and a lot of learning in store for you. A health insurance policy packs in several features and caveats. To give you a ready comparison, we designed Mint Mediclaim Ratings (MMR), which was developed by SecureNow Insurance Broker Pvt. Ltd. The full ratings along with the methodology can be seen here: http://www.livemint.com/mintmediratings . In the ratings, for family floater plans, we have considered two sum insured amounts (Rs.10 lakh and Rs.20 lakh) and three age categories in each—eldest insured member is 35, 45 or 65 years old. For individual plans, the age categories are the same but the sum assured is Rs.5 lakh. The newest edition of the ratings (January 2015) has a new category of individual plans of Rs.10 lakh for senior citizens aged 70 years. This week, we spotlight family floater policies with sum assured Rs.10 lakh, the eldest person being 45 years old and the coverage is for two adults and two children. We also explain some of the important aspects that one should look at while choosing a policy. Let’s look at co-payment.
