On Wednesday, the CBO estimated that enacting the bill would increase the budget deficit by $531 million between 2013-2017 and by about $1.1 billion between 2013-2022. The estimates assume no pay-for measures for the bill.
Some Democrats oppose the measure, saying it would weaken standards designed to protect consumers. Some experts also question how much the MLR threatens insurance brokers' business, arguing that agents are also the victims of an increasingly unfriendly market.
But Republicans say the bill is important to ensure that consumers can still avail themselves of brokers' help.
Energy and Commerce Chairman Fred Upton (R-Mich.) said in September that under the current MLR, "it will become harder to shop for a plan you like and can afford" as agents see less business.
