ITA about not disclosing more than you need to. There's no need for anyone to have your dxs--none at all. Not at this stage. You do need to tell them if you need accommodations and what those would be. Or if you don't think you will need accommodations, state "no" to that. If you find you do later, you tell your HR person and manager what they are. At that point, you find out what type of documentation your Employer needs and get it.

Too much information such as MVA w/jury trial and implant and etc.... is too much. You were in an MVA. You couldn't work. The rest is YOUR business. If they're that desperate for knowledge about you let them go look for it themselves.
