mine is claims made I have no idea what the difference is. I finished residency and rented an office from a former attending in his suite, he told me what kind of insurance to buy, what company to use, the name of a biller. I have to keep this company until I retire to get tail coverage, but they give you like 1500 for staying five years and a little bit. I don't know if its my carrier that is so expensive or it's Michigan. But my practice is about an hour from my home because it was way more expensive in the counties closer to home. It was less expensive the first three years and went up a little each year and now it's 6400 a year for 20 hours a week. I have been waiting for a quote for a week.
