Sadly, I am sure this goes on more often than we will ever know. Years ago I worked for a dentist. When I first started with him he was seeing Medicaid patients. Shortly after that he stopped seeing any new Medicaid but still saw his old Medicaid patients and anyone who was already a patient but now unfortunately found themselves on Medicaid. If my memory serves me right, a routine cleaning under Medicaid provided a reimbursement of something like $6 while a regular insurance provided a reimbursement of $30. Remember this was years ago so the numbers I am sure have drastically changed, but you can see the huge difference in compensation. It is a matter of greed for sure.
