Apparently I had the wrong bill version number, as Whenifhow kindly pointed out.
The correct version, H. R. 4872, does NOT have an Independent Medicare Advisory Board or Independent Cost Advisory Board.
So the unconstitutional horror of a 15 member panel writing laws wholesale does not seem to be in THIS bill, yet.
Since I got confused, you should check the version and bill number, but I think I got it right.
There is a 9 member advisory panel dealing with education, a 15 member Advisory Committee dealing with health workforce statistics, a Health Benefits Advisory Committee (death panel, I think), a TELEHEALTH ADVISORY COMMITTEE, but not the committee in the article.

is the public law and it DOES have Independent Medicare Advisory Board.
I was wrong about being wrong.
