There have been products in the past that were disease / organ specific and were sold especially with joint participation with single specialty hospitals, but of late such have become uncommon. The reason for this is that there are competing products in the market that offer coverage for an entire spectrum of ailments, which makes them more popular. I recommend that you take any health insurance cover that will give you more coverage as well. Recently, the health insurance covers launched by various companies are very attractive, especially the ones launched by Reliance General insurance company.
