Several months after back surgery, Linda Burdick sat holding a hospital bill for almost $60,000.
And this was after her insurance had paid its share of the bill. She had no idea she'd be billed for anything close to that amount.
"And just said to my husband, 'Oh my God, we're going to owe $60,000 to the hospital. How are we ever going to pay that?'"
The bill Burdick received is called a "balance bill." When the insurance company doesn't pay the total charge, doctors and hospitals often bill patients for the balance. The problem is, millions of balance bills these days are either illegal - or they are highly inflated.
Last year in California alone, the insurance industry reported that 1.7 million patients had been "balance billed" $528 million above what the patients owed.
Burdick hired two billing investigators. After demanding an itemized accounting, health care navigators Lin Osborn and Beth Morgan believe Burdick was overcharged by $40,000, for items like six surgical screws - at $1,750 each. They say overbilling is now the norm.
"Outright wrong is 100 percent," Osborn said. "I've never seen a hospital bill that I thought followed all the regulations correctly. Not once."
Burdick also asked her state attorney general, Richard Blumenthal, for help. Blumenthal's office has handled thousands of balance bill complaints.
"There's no explanation for some of them except purposeful balance billing or overcharging," Blumenthal said.
"If you don't fight, you are going to lose," Burdick said.
Burdick's fight applies to anyone with a suspect medical bill. All patients have the right to an itemized bill. Any charge can be disputed directly with the hospital.
