Five important features to look out for in the policy. One is that some policies have a sub-limit within their policies. For instance, some policies say that there is a restriction of 1 percent on a room rent, which means that if a person has a Rs 3 lakh mediclaim cover; 1 percent of Rs 3 lakh is about Rs 3,000. So the individual is entitled to a room which is upto Rs 3,000 per day. But for some reason he gets into a room which is Rs 5,000 or Rs 6,000 per day charge because he does not get a normal room, he chooses a room of higher category. Now the expenses that the insurance company will bear is going to be proportionate to the category, which he is entitled to which is Rs 3,000 per day. Hospitals do have a practice of charging the operation theatre charges and surgeon's fees depending on the category of room that you are in. It is more appropriate for an individual to buy a policy, which does not have these sub-limits within the policy.

Another thing which a person needs to look out for is that there is a levy on claims that you make. There is a loading that an insurance company levies in case you have made a claim. For example the same person with Rs 3 lakh cover makes a claim of Rs 2 lakh in a year, which is more than 50 percent of his sum insured. Next year when the policy comes for renewal insurance companies penalize the individual and charge him almost double the premium of what he has paid last year. You need to be careful if that clause is included in your mediclaim policy.

The other thing is a co-pay clause. In every claim, if there is a co-pay clause of 20 percent, the consumer will need to pay 20 percent of every claim, irrespective of it being within the limit of his sum insured. For instance taking the same example of an individual having a Rs 3 lakh cover and he makes a claim of Rs 1 lakh and there is co-pay clause of 20 percent. The individual will have to bear 20 percent on himself and the rest will be borne by the insurance company.

Then is also another point that the individual needs to look out for and that - is there a maximum age till when the insurance company will cover you, which is say 65 years or 75 years of age. One need to ensure that the policy is going to promise to cover you even beyond 75 years of age, that you are going to live and gives you lifelong cover.
