The present limit is Rs. 15000 although actual expense is much higher especially in case of combined family's health insurance. This type of insurance is taken by those who have no reimbursement facilty for medical treatment from their employers. Hence the amount of premium on medical insurance is dependent on one's need to protect family's medical necessities and no luxury at all. In fact, I, being a retired, spend around Rs. 20000 per year for Mediclaim worth Rs. 3 lacs each for myself and my wife. Therefore, the actual spending ( instead of limitation )on this score may please be exempted under Section 80D
