Ezra Klein has a link to some of the key provisions that take effect this year. There are a lot, so for now let me flag a few that I think may be of most interest to Slog readers:

EXTENDS COVERAGE FOR YOUNG PEOPLE UP TO 26TH BIRTHDAY THROUGH PARENTS’ INSURANCE: Requires health plans to allow young people up to their 26th birthday to remain on their parents’ insurance policy, at the parents’ choice. Effective 6 months after enactment.

IMMEDIATE HELP FOR THE UNINSURED UNTIL EXCHANGE IS AVAILABLE: Provides immediate access to insurance for Americans who are uninsured because of a pre-existing condition—through a temporary high-risk pool. Effective 90 days after enactment.

ENDS RESCISSIONS: Bans health plans from dropping people from coverage when they get sick. Effective 6 months after enactment.

BANS LIFETIME LIMITS ON COVERAGE: Prohibits health plans from placing lifetime caps on coverage. Effective 6 months after enactment.

BANS RESTRICTIVE ANNUAL LIMITS ON COVERAGE: Tightly restricts new plans’ use of annual limits to ensure access to needed care. These tight restrictions will be defined by HHS. Effective 6 months after enactment. (Beginning in 2014, the use of any annual limits would be prohibited for all plans.)

PROHIBITING DISCRIMINATION BASED ON SALARY: Prohibits new group health plans from establishing any eligibility rules for health care coverage that have the effect of discriminating in favor of higher wage employees. Effective 6 months after enactment.

SMALL BUSINESS TAX CREDITS: Offers tax credits to small businesses to make employee coverage more affordable. Tax credits of up to 35 percent of premiums will be immediately available to firms that choose to offer coverage. Effective beginning for calendar year 2010. (Beginning in 2014, the small business tax credits will cover 50 percent of premiums.)

And there's a lot more where that came from.
