Top up health insurance should be purchased from same company of which we have basic mediclaim policy or it should be purchased from company other than from which basic mediclaim is purchased.?
It is always best to buy the top up plans where you have base plan. Because it eases the process and claim settlement process. Because if you submit the documents at one point, then its enough.
There is no hard rule that to buy top plan you must have health insurance from the same company or even from different company. Hence, it is all about comfort.
