The article could have been entirely summed up by saying "health insurance has underwriting." If you are uninsurable, money won't buy you life insurance, disability insurance, or long term care insurance either. The person in the article admits to having or needing future testing or surgery. That is an automatic decline with all insurance companies until the issue is resolved, under control, or a diagnosis has been made. I'm surprised their agent even had them apply for a policy if that was known up front. The agent also apparently doesn't know what they're doing if they think applying separately would get them approved any differently than applying together.
There is some info missing from this story....something tells me not all of the facts have been disclosed. Would be interesting to see the application and hear the insurance company's side of the story. I often see these type of articles blaming the insurance industry. When all of the facts are made clear, it's usually easy to see why the person was declined. If I had a nickel for every time I heard something to the effect of "well I just have a little bit of diabetes, nothing major" or "I had a heart attack four years ago, but my doctor says I'm in great shape now!" well....I'd have a lot of money.
The article basically says "we have issues, we just want the insurance company to pay for it." Most people have had group plans their entire lives and don't think twice about being uninsurable on the individual market. Of course, that's why group health insurance is so expensive...the article also fails to mention their COBRA or HIPAA options, so yes, money could buy them health insurance, they just didn't like those options.
