HIPAA may have something to say about doctors leaking patient information to Facebook.

  You have to intentionally leak medical information. Much of our laws are about intent. The other comments cover what most likely happened (both visiting FB on the same wi-fi, the physicians website or hospital website had a tracking pixel from some 3rd party service that got aggregated back and sold to FB, etc.) Keep in mind FB is only making a guess based on attributes it's been fed. I'm sure friend suggestions may also include other people who have visited the same hospital you have nothing in common with. They're hoping to get a few friend hits by aggregating as many signals as possible.
