I just went to my lawyer handling my Workman's Compensation case.?

I was told to sign an Authorization to disclose protected Health Information to allow opposing lawyers from workman's compensation to view so a settlement can be reached. I was not given a copy and don't know exactly what information is being released. No protected Health information involving the claim is of any concern. However I do have protected Health information from several years ago I do not want released. Such as information involving my Federal Pension Disability and of course my records relating to Mental Disorders. Hey nobody is perfect. Would anyone know if this particular information would be released or just protected health information involving the workman's compensation claim. If someone may know exactly what health information is released I would appreciate knowing exactly what I signed. I do know I can revoke this authorization. Any help here? I'm only concerned that information regarding the terms of my Federal Pension Disability and mental heath status could become a matter of public record. Is this possible? Thank you.
