If your home visit is refused then ATOS will offer you an appointment at one of their HealthCare Centres.
If you refuse to attend, a second opportunity to attend the medical will be offered, if this is refused then your file is returned to the DWP as a no show.
The DWP
should write to you asking for you to show Good Cause why you did not attend, you condition would be an example of Good Cause.
A DWP Decision Maker will then make a Decision on your case. If they find for you I would expect it would result in a home medical, however, if they find against you, then your claim will be closed and you will need to appeal the Decision.
Let's hope it doesn't get that far
