The 113th Congress will be the first one in 40 years to convene without California Rep. Pete Stark as a member.

Stark was defeated in November by a fellow Democrat under new California voting rules. Stark may not be a household name, but he leaves a long-lasting mark on the nation's health care system.

Most of the really big changes made by the 2010 health law don't start for another year. That includes things like a ban on restricting pre-existing conditions, and required insurance coverage for most Americans. But Jan. 1, 2013, will nevertheless mark some major changes.

When it comes to reducing Medicare spending, asking wealthier seniors to pay more is one of the few areas where Democrats have shown a willingness to even consider the subject.

"I do believe there should be means testing. And those of us with higher income in retirement should pay more," said Sen. Dick Durbin, D-Ill., on last Sunday's Meet the Press. "That could be part of the solution."

At least in public, Republicans have been clear that they see the current budget negotiations as a chance to address what they see as the source of Washington's deficit problem: major entitlement programs.

The Affordable Care Act, as passed by Congress in 2010, assumed that every low-income person would have access to health insurance starting in 2014.

That's when about 17 million Americans — mostly unmarried healthy adults with incomes up to 133 percent of poverty, or about $15,000 a year — would gain access to Medicaid.

Dozens of medical, women's health and reproductive health groups marked the first anniversary of Health and Human Services Secretary Kathleen Sebelius' decision to maintain age restrictions on the sale of the morning-after birth control pill without a prescription by urging her to reconsider that decision.

Friday marks a not-so-happy anniversary for some of President Obama's biggest supporters: It's exactly one year since Health and Human Services Secretary Kathleen Sebelius decided not to lift the age restrictions on availability of the so-called morning-after pill, Plan B.

There's not much in health care that economists agree on. But one of the few things that bring them together is the idea that excluding the value of health insurance from federal taxes is nuts.

What's the largest tax break in the federal tax code?

If you said the mortgage interest deduction, you'd be wrong. The break for charitable giving? Nope. How about capital gains, or state and local taxes? No, and no.

Believe it or not, dollar for dollar, the most tax revenue the federal government forgoes every year is from not taxing the value of health insurance that employers provide their workers.

Whenever the discussion turns to saving money in Medicare, the idea of raising the eligibility age often comes up.

"I don't think you can look at entitlement reform without adjusting the age for retirement," Sen. Lindsey Graham, R-S.C., said on ABC's This Week last Sunday. "Let it float up another year or so over the next 30 years, adjust Medicare from 65 to 67."
