I was a customer of Mega Health Insurance Co. around 2005 - 2006. Not only did I have to report them they arbitrarily raised my premiums.
In 2006 I was treated for a malignant brain tumor - surgery, MRIs, Care in ICU. Every time I checked my account all of the claims were shown as "Under review". I finally had to contact the Colorado Dept of Insurance.
The woman I spoke to there had no love for Mega Insurance. She proceeded to give them a deadline in which they either started paying claims or provide an explanation for not paying claims. Two days before the deadline - guess what? Claims were being paid.
Thankfully shortly after I cancelled my policy with Mega I was able to get on Medicare. I will NEVER recommend anyone purchase insurance from this company.
