Star Rating for Biosimilars Act
This bill requires the Centers for Medicare & Medicaid Services (CMS) to establish quality measures regarding biosimilar biological products under the five-star performance rating system for Medicare Advantage plans. The measures must assess the level of access that plans provide to covered biosimilars, including with respect to formularies, cost-sharing, and utilization management.
The CMS must also incorporate such measures into similar rating systems for plans under the Medicare prescription drug benefit.
To amend title XVIII of the Social Security Act to require the 
Secretary of Health and Human Services to add a new set of measures to 
the 5-star rating system under the Medicare Advantage program in order 
    to encourage increased access to biosimilar biological products.

    Be it enacted by the Senate and House of Representatives of the 
United States of America in Congress assembled,

SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Star Rating for Biosimilars Act''.

                                addition to the reference biological 
                                product.

                                percentage of enrollees prescribed the 
                                biosimilar biological product when the 
                                reference biological product is also
