In written comments, many of the hospitals have thanked the office for professionalism and helpful feedback.
Most of the audit targets contacted by Modern Healthcare declined to comment or didn't return calls, but the experiences described by the executives who did respond suggest those formal letters don't tell the whole story.
Officials at two hospitals said the auditors didn't seem knowledgeable about the complex healthcare coding issues facing the industry. And they said the final audit reports were written to make it seem as though something other than human error may have led to billing disputes.
“Bottom line, I was not impressed with the entire process, and much of it was caused by the auditors assigned to us not having the appropriate expertise to do a healthcare audit,” Christine Newgren, University of Colorado Health chief compliance officer, said in an e-mail.
And it's not clear how the inspector general's office was selecting the hospitals that were singled out for the audit treatment.
Hospitals received about $168 billion in 2011 to care for Medicare beneficiaries, and an untold portion of that 12-figure sum was lost to waste, fraud and abuse—some of it intentional and some not, officials say.
To date, the office has released the results for about 42 hospital Medicare compliance audits, and another 45 are in progress. The efforts have returned about $20 million to Medicare so far, or about $480,000 per audit. Investigators say each noncompliant claim for Medicare services averages about $1,700 in overpayments.
“We have to pay attention to where the money that is paid to hospitals is going,” Office of the Inspector General Chief Counsel Greg Demske told a banquet hall full of health lawyers and compliance officials this month at the annual Fraud and Compliance Forum in Baltimore. “As we do more of these, we further refine how we engage in these audits.”
In written responses to auditors available publicly, many of the hospitals thanked the inspector general's office for its work and admitted that the issues brought to light by auditors should have not have been billed as they were.
For example, officials with 339-bed West Florida Hospital, an HCA facility in Pensacola, agreed to repay $172,995 after concurring with the auditor's finding that 151 of the 208 claims reviewed by investigators contained billing errors.
“We appreciate the OIG's audit review for the 2009 and 2010 years,” Chief Financial Officer Randy Butler wrote to the agency in a May 31 letter that also outlined how staff received additional training and internal policies were beefed up after the probe.
Stephanie Barnes Taylor, the chief legal officer for 381-bed Singing River Hospital in Pascagoula, Miss., was not so sanguine.
She said she still remembers the feeling when she learned in August 2011 that the inspector general's office had some questions about the documentation to support $3.4 million in Medicare payments the hospital received between 2008 and 2010.
“Obviously, it is always a bit anxiety-provoking when you get a notice from the OIG about a potential audit,” Taylor, who was chief compliance officer at the publicly owned hospital at the time, said in an interview.
As the auditors took up residence in a conference room at the hospital, she remembered thinking that although the auditors were professional and courteous, they didn't seem well-versed in the complex world of healthcare billing.
“The auditors weren't very familiar with a lot of the processes,” she said.
Singing River officials got the chance to work directly with the auditors before and after they turned over electronic documentation to support the 100 inpatient and 269 outpatient Medicare claims that the inspector general's office had turned up as questionable through data-mining of the hospitals bills. Although Taylor felt the hospital could support all of the bills, auditors ultimately concluded that 192 of the claims lacked supporting documentation.
After a yearlong investigation, the hospital first learned through a public filing—not a direct letter from the inspector general's office—that the auditors had concluded the hospital received $515,651 in overpayments over the three years.
The audit report had two main findings: that the hospital incorrectly billed Medicare for $390,276 worth of small-dose Lupron cancer treatments when larger, less expensive doses were used and that it billed $120,789 for inpatient visits that should have been outpatient stays. The hospital is still contesting the findings with its Medicare Administrative Contractor, which has tried to recoup the payments.
Although the hospital disagreed with both conclusions, auditors noted that they had removed allegations in their original draft report that said physicians had actually prescribed Lupron for reasons other than those approved by the Food and Drug Administration.
