Very few people really have an obligation to treat with a company doctor. Unless your employer complies with the law and regulations governing treatment by a company doctor, you are free to treat with a physician or medical provider of your choice. You can go to any physician or medical provider if your employer fails to return your calls. You can also get in touch with the insurance company directly to report your claim and request information.
