OK! Finally got my Mass Health going.
UMass Worcester Program with Dr. Kelley take MassHealth and so does the Fallon Bariatric Program if you have any of the plans they accept (like MassHealth Blue Cross or MassHealth FCHP, or a list of many others accepted all of them listed on http://www.fallonclinic.com/internet/index.aspx ) I don't know of any prgrams closer to Springfeild.
I did a little poking around and found this center. I don't know anything about them, but it is closer to you that the ones mentioned. The link is http://www.pvweightloss.com/
