...Not much more than during your residency, unfortunately. You are a "PGY 4..., etc" and basically the step up is a few thousand a year more than your general internal medicine salary. Some programs may be slightly more than others, ie, private hospitals sometimes pay more than, say county facilities. The way that you can make up for the lack of green during fellowship is moonlighting- as a subspecialty fellow, at least in my geographical region, you are sought after for not only moonlighting ops in your subspecialty, but in general internal medicine.
