"Important – Please contact us to provide more information."
That's what the letter from Independence Blue Cross said. Dated 7/28/2015, it arrived 8/4/2015, and informed me that I need to "call or respond online within seven business days to ensure that your future claims and those of your family members can be processed in a timely manner." So today is the deadline.
What do I need to contact them about? "We are required to determine if you or your family members have other health insurance coverage to process your claims."
OK, fair enough. And they inform me that "You can choose the most convenient way to provide this information to us". The first option is to "Simply dial 1-866-507-6575 and follow the prompts on our easy-use interactive voice response system"; the second option is "to visit our member website at www.ibxpress.com".
But it turns out that there are a couple of problems. The first problem is that both methods fail at the first step. And the second problem is that there's apparently no other way to contact them to "provide more information … to ensure that your future claims and those of your family members can be processed in a timely manner".
