I read on another post somewhere that DO's in some specialties (such as surgery) can have problems with insurance companies refusing payment because they are not certified by (some acronym here--ABSM? ABSE?--I think basically b/c they are not an MD). Anyhow, there is a Canadian doctor in my home town that is having problems with insurance simply b/c he is Canadian! I know that companies can be pretty flaky sometimes about this. If anyone has knowledge of this, please post.
