From the ADA:
Illinois is the latest state to issue regulations on how health care providers, including dentists, can participate in social couponing websites without violating unethical fee-splitting laws.
The Illinois Department of Financial and Professional Regulations on April 10 issued a statement that says as long as health care providers follow certain rules, advertising their services using vouchers does not constitute unethical fee-splitting.
Groupon of course is just a fancy e-coupon. Even if it is legal and ethical is it professional, is it effective? In other words does the use of a coupon project a professional image? Will it attract good long term patients? Could it repel good long term patients?
So far the answers to these questions have been mixed. Some dentists report very large responses to the Groupon offer with very few of these responders becoming long term patients. This is similar to the experience many dentists have with old fashioned mailed coupons.
