On a 2007 Mva that was totally covered by insurance. The case was closed by Insurance Co. 6/09 and I did not become Medicare elegible until 9/1/09. They are trying to make paid charges all relate to injury 3/07 to my current bills and Dr. care. Where do I go to get help. Medicare simply will not cooperate or understand that I owe nothing.
Like an $$ award above the medical costs paid by your health insurer back in 2007 -2009. If so, you might be dealing with recovery due to Medicare Secondary Payor Act. I think Act was signed in back in 2012 or maybe 2013 & retro'd back 5 years. Award $ can be recouped if Medicare pays for care arising from follow up due to the accident that settlement $ given for.
If there was a settlement, I'd contact your old personal injury atty to help you figure out if thus is the issue & sort this out.
I hope many others with Medicare related issues post their advice for you, and it might help me too. Maybe I'll bring the documents myself in person to a SS office, as already suggested -
