If your employer had the type of AETNA insurance that just has AETNA reviewing & paying claims... is it your employer's money used to pay the bills instead of AETNA's money? If it is, then it's very possible your employer is aware of all your health information including labs, diagnoses, vital signs, medications & every chart ever made on you. The employer is the "payor" and possibly has access to all of your information. It's seems wrong to alert employers of high risk / "high dollar" employees. I expressed my concerns about this and didn't get far. They claim the employer doesn't have the name of the actual employee costing them so much $$$.
I wonder though if an employer could figure out which of it's employees has been in the ICU for 20+ days? It doesn't seem too difficult for them to figure it out.
