It is unlawful and punishable under Section 59 for any person licensed under this Act to knowingly advertise that the licensee will accept as payment for services rendered by assignment from any third party payor the amount the third party payor covers as payment in full, if the effect is to give the impression of eliminating the need of payment by the patient of any required deductible or copayment applicable in the patient's health benefit plan.
As used in this Section, "advertise" means solicitation by the licensee or through another by means of handbills, posters, circulars, motion pictures, radio, newspapers, television or in any other manner.
