If this invitation came by email — likely it came as a result of your internet searches. If it came by mail personally addressed to you — then you need to discover the sender. Health care providers and your insurance company are permitted to provide patients or insured with health information related to treatment. If it comes from someone unknown to you then 1) check wth your doctors to see if they know anything about it and if they do not then 2) file a complaint with HHS — https://www.hhs.gov/hipaa/filing-a-complaint/index.html
By the way it is HIPAA, not HIPPA or HIPIA
Thanks, My mistake, I cannot type either. LOL
