The MA legislature states...
"Section 13. Podiatry as used in this chapter shall mean the diagnosis and the treatment of the structures of the human foot by medical, mechanical, surgical, manipulative and electrical means without the use of other than local anesthetics, and excepting treatment of systemic conditions, and excluding amputation of the foot or toes. This and the ten following sections shall not apply to surgeons of the United States army, navy or of the United States Public Health Service, nor to physicians registered in the commonwealth. The term physician and surgeon when used in sections twelve B, twelve G, twenty-three N and eighty B shall include a podiatrist acting within the limitation imposed by this section."
TLDR, no ankle privileges and no amputations.
However, how it really works in MA is that certain hospitals will allows DPMs to practice full scope, but that is entirely dependent on the hospital. For example, Mt. Auburn allows the DPMs there to do everything. Dr. Basile probably does more TARs and complex recons than anyone in the Northeast and he works out of Mt. Auburn. However, that could all change, theoretically, if the hospital ever had a change of heart based on the current legal definition of podiatry. There are also some programs in MA though that you need to scrub with general or vascular to do toe amps. I would highly suggest spending time at any program in MA that you're seriously considering to see how things actually work. There are good programs in MA, but the rules/laws are confusing to say the least.
