My insurance changed from a PPO to and HMO and my the PHO that my primary care doctor is part of just joined an ACO and now I am under a Global Payment plan...what the heck does that all mean?? There is a battle raging on Capitol Hill about Health Care Reform and with that battle comes a whole new group of abbreviations and terms that we all need to be aware of in order to better understand what people are talking about. We have prepared a brief glossary of some of the terms that can help you to better understand the terms and abbreviations being used...it's not all inclusive, but at least it's a start. Just click on the photo to the right to be taken to the glossary of terms.
