#NationalNurseWeek (CBS News) HOUSTON – In Washington, the Supreme Court heard a third and final day of arguments over the health care law backed by President Barack Obama. It requires all Americans to have health insurance or pay a fine.

It was passed two years ago to help nearly 50 million Americans who are uninsured get coverage. Nowhere is the problem greater than in Texas where nearly 25 percent of state residents lack coverage.

CBS Correspondent Ben Tracy reports on a nurse who is helping to fill the gap.

Nine-year-old Georgia Shivers had a big wood splinter lodged in her foot. A visit to a doctor was not an option. Her mom Kristy does not have health insurance. It would cost her $400 per month.

“We need groceries and you know, pay bills, and insurance is just too much right now,” says Kristy Shivers.

So, Shivers had a dilemma. “I was going, ‘Uh, we’re going to have to go to the emergency room for this because there was nowhere else to go.’”

Her best alternative turned out to be in a Houston area strip mall, where Melissa Herpel opened a clinic in June for those without insurance.

“On most days, I’m averaging anywhere between 15 to 20 patients,” Herpel said.

The 31-year old nurse practitioner is allowed to do almost everything a general practitioner can do except deliver a baby.

“When you think of uninsured nowadays, you think of poor, you think of low income, you think of a tiny shack house with someone who has no amenities,” said Herpel. “That’s not the case anymore.”
