Huh?
From the NY Times, I am having a hard time reconciling these statements from the same article:
First statement:
The law provides a partial exemption for certain health plans in existence on March 23, when Mr. Obama signed the legislation. Under this provision, known as a grandfather clause, plans can lose the exemption if they make significant changes in deductibles, co-payments or benefits.
About half of employer-sponsored health plans will see such changes by the end of 2013, the administration says in an economic analysis of the rules.
Second statement:
About 133 million Americans are in group health plans from employers with 100 or more employees, the administration said, and most "will not see major changes to their coverage as a result of this regulation."
My translation: Yes, you will lose your current health plan despite Obama's promises, but he doesn't want you to realize this until 2013, conveniently just after the next presidential election.
