Thats answered in section 122:
“Health Benefits Advisory Committee to recommend covered benefits and essential, enhanced, and premium plans.” This will be chaired by the Surgeon General and will have “9 members who are not Federal employees or officers and who are appointed by the President”, “9 members who are not Federal employees or officers and who are appointed by the Comptroller General”, and an “even number of members (not to exceed 8 ) who are Federal employees and officers, as the President may appoint.” A committe with up to 27 members, 18 of whom are picked by the President. The bill says these people will “reflect providers, consumer representatives, employers, labor, health insurance issuers, experts in health care financing and delivery, experts in racial and ethnic disparities, experts in care for those with disabilities, representatives of relevant governmental agencies, and at least one practicing physician or other health professional and an expert on children’s health”. But with no checks and balances on the selection of this group, you can only hope that absolute power does not corrupt absolutely.
