Did my employer violated my HIPPA rights by attending my doctors’ appointments when I was assigned a workers compensation nurse?

You need to talk with your lawyer about that. I typically do not allow nurses or employers or adjusters in the examining room during exams. I also make the nurses agree not to testify against my client before allowing them to provide services. Alabama comp law allows the employer to have access to your medical care information. However, I do not know how that affects your HIPPA rights, as those are Federal laws. I do know that you have your patient/physician privilege to privacy, though, and you can insist on exams being private. The Dr. has to honor that. Discuss strategies with your lawyer. Good luck.
