(CBS) According to the FBI, all you have to do to get into this business is rent a cheap storefront office, find or create a front man to get an occupational license, bribe a doctor or forge a prescription pad, and obtain the names and ID numbers of legitimate Medicare patients you can bill the phony charges to.
"There's a whole industry of people out there that do nothing but provide patients," Waterman told Kroft.
Asked what he means by "provide patients," Waterman said, "I'm just talking about lists of patients, people's names, Social Security numbers, addresses, and date of birth. With those four things, you can bill for a patient."
Asked where Tony got his fictitious customers, he told Kroft, "They'll be people that would sell you a list of maybe $10 per patient. And I'll buy 1,000, 10,000 maybe at a time. And then you just fill in the patient's name and you send it. And then I used the same patients with the same company and then the next company I used the same patients and I kept using them, and they'll pay for the same patient every time."
Once the crooked companies get hold of the patient lists, usually stolen from doctors' offices or hospitals, they begin running up all sorts of outlandish charges and submit them to Medicare for payment, knowing full well that the agency is required by law to pay the claims within 15 to 30 days, and that it has only enough auditors to check a tiny fraction of the charges to see if they are legitimate.
If they're not, it's usually people like 76-year-old Clara Mahoney who catch them.
She began to notice all sorts of crazy things turning up on her quarterly Medicare statements back in 2003 - things that Medicare paid for on her behalf that she had never ordered, never wanted and never received.
"Air mattresses, a wheel chair, urine bag for my leg," Mahoney said, listing some of the unwanted items Medicare was charged for on her behalf. "It was getting so I didn't wanna open up the explanation of benefits because you know, it's like, 'Oh, no. Not again.'"
