You may want to consider implementing a private pay version of the ABN or waiver so that your patients would be better informed. Well informed patients would subsequently result to better satisfaction. It is always a good idea to have your patients, with any insurance, to be pre notified and sign that they agree to pay for any service that may be considered non covered or not "medically necessary."
