    (b) GAO Study and Report.--
            (1) Study.--The Comptroller General of the United States 
        (in this subsection referred to as the ``Comptroller General'') 
        shall conduct a study on supplemental benefits provided to 
        enrollees in Medicare Advantage plans under part C of title 
        XVIII of the Social Security Act. Such study shall include an 
        analysis of the following:
                    (A) The type of supplemental benefits provided to 
                such enrollees, the total number of enrollees receiving 
                each supplemental benefit, and whether the supplemental 
                benefit is covered by the standard benchmark cost of 
                the benefit or with an additional premium.
                    (B) The frequency in which supplemental benefits 
                are utilized by such enrollees.
                    (C) The impact supplemental benefits have on--
                            (i) indicators of the quality of care 
                        received by such enrollees, including overall 
                        health and function of the enrollees;
                            (ii) the utilization of items and services 
                        for which benefits are available under the 
                        original Medicare fee-for-service program 
                        option under parts A and B of such title XVIII 
                        by such enrollees; and
                            (iii) the amount of the bids submitted by 
                        Medicare Advantage Organizations for Medicare 
                        Advantage plans under such part C.
            (2) Report.--Not later than 5 years after the date of the 
        enactment of this Act, the Comptroller General shall submit to 
        Congress a report containing the results of the study conducted 
        under paragraph (1), together with recommendations for such 
        legislation and administrative action as the Comptroller 
        General determines appropriate.

Summary: This bill allows a Medicare Advantage (MA) plan to provide certain supplemental benefits to chronically ill enrollees beginning in plan year 2020. The Government Accountability Office must report to Congress on the provision of such supplemental benefits to MA enrollees.
