When you're online, do a search for short term health insurance quotes with one of the major search engines. Visit health insurance sites that look promising and evaluate their overall look and feel of their site, their company profiles, and offers for free quotes. This will give you a general feel for their health insurance offerings and professionalism.
Complete the short application forms to get a detailed health insurance quote and don't be afraid to inquire about their price structure and coverage benefits. Short list those companies that you are most interested in.
Do a comparison of benefits. Not all health insurance plans are alike. Do a side-by-side comparison of the benefits and terms of the short term medical plan which will inevitably save you a lot of headaches down the road. Be careful not to make your decision solely on price. You may decide to go with the lowest cost option but it may not be the best option for you and your situation.
Contact any proposed companies to see how their customer service responds. Do they have online representatives available ready to assist? Is there a live phone number you can call if you have a problem? Are they responsive, friendly, and ready to help? What hours are they available should you need to reach them online or by phone?
