Actually, they have access to this information with your signed releases. It's part of your prior work history. It will be in your personel file with that employer, and part of your file regarding Workmans Comp.

I have collected workmans comp twice in 20 years. My broken toe...no work lose. Is still part of that record, since workmans comp paid the medical bills.

While they can't release "medical records" without consent. They can confirm the information you provide, and release. You were injured on the job, drew comp for X number of days. And...it will contain a copy of your "release" from Doctors care. Otherwise, your previous employer would still be obligated for benefits. Something I'm sure they wanted release from ASAP.
