Who else is supposed to aquire and submit the records? If I'm getting free money for five years and all that's required is a fax every five years, I wouldn't consider that particularly burdensome. I have to fill in a timesheet every week.
Maybe a better way to accomplish this is a free yearly physical with a doctor? The doctor can then be required to share any changes in disability with the government. Missing x years of appointments also stops your benefits. If you can't come to the doctor maybe they could do a house call?
