I already own several health insurance policies. What should I look out for if I would like to purchase more?

If you have previously purchased health insurance policies, you should note the following before buying another one:

• Multiple Medical Expense Policies
  The total reimbursement from all your plans is limited by the expenses you have actually incurred.  Buying additional medical expense insurance plans may not give you extra benefits.
• Switching Between Health Insurance Products
  Health insurance products usually do not cover any illness or disability you already have at the time you sign up.  If you make a switch to another health insurance product you may not be able to make claims relating to medical conditions that developed after you took up your original health insurance policy.
