In November of 2012 my wife got laid off and we had cobra coverage for 6 months through her company. I was already 65 years old and didn't know that under cobra I had to sign up for medicare part B.I thought coverage would be the same as while my wife was working, but I guess it only counts as a supplemental insurance. I had cataracts done and now the hospital is charging me $40,000! I talked to the actual doctor that performed the surgery and said even if people didn't have insurance to perform the surgery would only be $5000. How do I get my bill reduced to a reasonable price?
