R.I. Gen. Laws § 9-19-34.1
In the event the defendant so elects, in a legal action based upon a cause of action arising after January 1, 1987, for personal injury against a licensed physician, hospital, clinic, health maintenance organization, professional service corporation providing health care services under chapter 5.1 of title 7, dentist, or dental hygienist based upon professional negligence, the defendant may introduce evidence of any amount payable as a benefit to the plaintiff as a result of the personal injury pursuant to any state income disability or workers' compensation act, any health, sickness or income disability insurance, accident insurance that provides health benefits or income disability coverage, and any contract or agreement of any group, organization, partnership, or corporation to provide, pay for, or reimburse the cost of medical, hospital, dental, or other health care services. Where the defendant elects to introduce such evidence, the plaintiff may introduce evidence of any amount which the plaintiff has paid or contributed to secure his or her right to any insurance benefits concerning which the defendant has introduced evidence. When such evidence is introduced, the jury shall be instructed to reduce the award for damages by a sum equal to the difference between the total benefits received and the total amount paid to secure the benefits by the plaintiff or the court may ascertain the sum by special interrogatory and reduce the award for damages after verdict. Whenever an award is so reduced, the lien of any first party payor who has paid such a benefit against the judgment shall be foreclosed and the plaintiff shall have no legal obligation to reimburse the payor.
