If the provider wants to offer free/reduced services I would advise he discuss it with his legal counsel.. Putting out goodies is a good idea..but I hate being a stickler..I had a provider receive a citation from board of health for offering his patients donuts with the coffee.. go figure.. I thought that was ridiculous, he could put out coffee but not donuts? The board of health said it would be ok if the donuts/cookies were individually wrapped.. LOL guess they think doc's might poison the patients?
As I stated before, I usually just tell my clients to talk to their lawyers when it comes to those questions because it's not within the scope of my services.
