Doctors shouldn't even have to do it. The treatment center should be able to do it. For example:

  Rolled ankle
    100% [of patients get charged]: Office visit: $50
    58%: X-rays: $55 - $95
    22%: boot/cast: $240
    3%: surgery: ??
    <1%: other: ??

This would't work for all symptoms, but it would work for a lot. But no treatment center does this.
