Judging by their bills, it would appear that elderly patients treated in the emergency room at Baylor Medical Center in Irving, Texas, are among the sickest in the country — far sicker than patients at most other hospitals.

In 2008, the hospital billed Medicare for the two most expensive levels of care for eight of every 10 patients it treated and released from its emergency room — almost twice the national average, according to a Center for Public Integrity analysis. Among those claims, 64 percent of the total were for the most expensive level of care.

But the charges may have more to do with billing practices than sicker patients. A Baylor representative conceded hospital billing for emergency room care “did not align with industry trends,” but said that the hospital since 2009 has reined in its charges.

The Texas hospital’s billing pattern is far from unique. Between 2001 and 2008, hospitals across the country dramatically increased their Medicare billing for emergency room care, adding more than $1 billion to the cost of the program to taxpayers, a Center investigation has found. The fees are based on a system of billing codes — so-called evaluation and management codes — that makes higher payments for treatments that require more time and resources.

Use of the top two most expensive codes for emergency room care nationwide nearly doubled, from 25 percent to 45 percent of all claims, during the time period examined. In many cases, these claims were not for treating patients with life-threatening injuries. Instead, the claims the Center analyzed included only patients who were sent home from the emergency room without being admitted to the hospital. Often, they were treated for seemingly minor injuries and complaints.

Electronic medical records, long touted by government officials as a critical tool for cutting health care costs, appear to be prompting some doctors and hospitals to bill higher fees to Medicare for treating seniors.

The federal government’s campaign to wire up medicine started under President George W. Bush. But the initiative hit warp drive with a February 2009 decision by Congress and the Obama administration to spend as much as $30 billion in economic stimulus money to help doctors and hospitals buy the equipment needed to convert medical record-keeping from paper files.

In the rush to get the program off the ground, though, federal officials failed to impose strict controls over billing software, despite warnings from several prominent medical fraud authorities. Now that decision could come back to haunt policy makers and taxpayers alike, a Center for Public Integrity investigation has found.

Experts say digital medical records may prove — as promised — to be cost-effective, allowing smoother information sharing that helps cut down on wasteful spending and medical errors.

Yet Medicare regulators also acknowledge they are struggling to rein in a surge of aggressive — and potentially expensive — billing by doctors and hospitals that they have linked, at least anecdotally, to the rapid proliferation of the billing software and electronic medical records. A variety of federal reports and whistleblower suits reflect these concerns.

Regulators may lack the auditing tools to verify the legitimacy of millions of medical bills spit out by computerized records programs, which can create exquisitely detailed patient files with just a few mouse clicks.

“This is a new era for investigators,” said Jennifer Trussell, who directs the investigations unit of the U.S. Department of Health and Human Services Office of Inspector General.

When news broke last September that some doctors and hospitals could be using electronic health records to overbill Medicare, top government officials swung into action.

U.S. Health and Human Services Secretary Kathleen Sebelius and Attorney General Eric Holder fired off a stern letter to five prominent medical groups threatening criminal prosecution for applying the technology to bill for more complex and costly services than merited — a practice is known as “upcoding.”

But the Centers for Medicare and Medicaid Services, which reports to Sebelius, is taking a much less confrontational stance as it opens a “listening session” this morning in Baltimore on the digital billing controversy.

The agency has lined up nearly a dozen health industry speakers representing mostly hospitals, doctors and the software industry to give their take on fair and honest billing and coding standards to impose as medicine wires up. No one at the meeting will represent patients or others who pay medical bills.

A CMS spokesman called the meeting "another step toward ensuring appropriate use" of electronic records, which are "critical to our efforts to reform the health care delivery system, lowering costs while improving the quality of care.”

Six U.S. Senators are calling for an overhaul of the federal government’s $35 billion plan for doctors and hospitals to switch from paper to electronic medical records, citing concerns from patient privacy to possible Medicare billing fraud.

The report issued Tuesday by the half-dozen Republicans concedes that many lawmakers and medical experts believe the digital systems can reduce health care costs and improve the quality of care by reducing duplicative testing and cutting down on medical errors.

But the report asserts that the Obama administration’s push to use billions of dollars in stimulus money helping doctors and hospitals buy digital systems needs to be “recalibrated.”

“Now, nearly four years after the enactment…and after hundreds of pages of regulations implementing the program,” the document says, “we see evidence that the program is at risk of not achieving its goals and that $35 billion in taxpayer money is being spent ineffectively in the process.”

Federal officials, in an apparent effort to clamp down on Medicare fraud and abuse, are tightening scrutiny of the  growing numbers of doctors who rely on electronic medical records to bill for their services.

The Centers for Medicare and Medicaid Services has directed its auditors to look more closely to make sure the systems are properly documenting the services being paid for by the government. The new policy, announced in November, went into effect earlier this week.

The new directive was first reported by FierceEMR.

At issue is the impact electronic medical records can have on billing for doctor visits. Doctors must choose one of five escalating payment levels, known as “Evaluation and Management” codes that best reflect the amount of time spent with a patient as well as the complexity of the care.

Medical groups argue that computers make it easier for them to document all of the work they do, which leads to higher codes and fees. But officials worry that the software also can be manipulated to inflate bills — a practice known as “upcoding.”

The stakes are high. Medicare spent more than $33.5 billion in 2010 using these numeric codes for services ranging from routine doctor office visits to outpatient hospital or nursing home care. More than half the doctors billing Medicare were using electronic records in 2011, and that number has since grown further, officials said.

In early 2009, federal officials announced they would pay billions of dollars to hospitals and doctors who agreed to buy electronic medical records and use them to improve the quality of health care.

But the Centers for Medicare and Medicaid Services has since paid out more than $3.6 billion to medical professionals who made the switch without verifying they are meeting the required quality goals, according to a new federal audit to be released today.

The Department of Health and Human Services Inspector General’s audit warns that the electronic records program is “vulnerable” to abuse and that officials should immediately “strengthen” oversight to protect tax dollars from being wasted.  

Many experts believe electronic health records hold great potential to keep people healthier. To achieve that goal, government officials insisted that doctors and hospitals receiving payments meet a lengthy checklist of quality standards, ranging from writing prescriptions electronically to recording immunization and smoking histories.

Yet it’s not clear if that’s happening because nobody checks to make sure. In a response included in the audit report, CMS Acting Administrator Marilyn Tavenner said that requiring medical professionals to prove they are meeting the quality requirements prior to cutting them a check would be burdensome and “significantly delay payments.”

Tavenner said that the agency plans to conduct some audits in the future and would then take steps to recover any improper payments. But the Inspector General opined that CMS should verify compliance first to avoid having to track down miscreants later, a much maligned practice sometimes referred to as “pay and chase.”

The nation’s largest hospital group has asked federal officials to create new Medicare pay scales for emergency rooms and outpatient clinics and determine if electronic health records are prompting hospitals to overcharge the federal program.

The American Hospital Association, which represents about 5,000 hospitals nationwide, also signaled that it wants to work with law enforcement officials to write Medicare billing standards that keep its members on the right side of the law.

Hospitals want to ensure that they “receive only the payment to which they are entitled,” Rich Umbdenstock, the group’s president, wrote in a letter dated Nov. 12. The letter was sent to Department of Health and Human Services Secretary Kathleen Sebelius and Attorney General Eric Holder.

“Hospitals share the administration’s goal of a health system that offers high-quality, affordable care and work hard to ensure billing is correct the first time,” Umbdenstock wrote.

The industry has come under fire in the wake of the Center for Public Integrity’s “Cracking the Codes” series, which found that thousands of medical professionals have steadily billed higher rates for treating seniors on Medicare over the last decade — adding $11 billion or more to their fees. The investigation suggested that Medicare billing errors and abuses have been worsening as doctors and hospitals switch to electronic health records.

Federal officials will focus on possible Medicare overbilling by doctors and hospitals that use electronic medical records, a top government fraud investigator said  Wednesday, in announcing investigative priorities for the coming year.

“Electronic medical records can improve quality of care and efficiency and help us uncover cases of fraud and abuse. At the same time, we must guard against the use of electronic records to cover up crime,” said Daniel Levinson, the Department of Health and Human Services inspector general, in a video presentation.

The video posted on the agency’s website on Wednesday summarized the inspector general’s “work plan,” for 2013, a listing of Medicare and Medicaid fraud fighting efforts the agency plans to emphasize.  

The plan states that the agency “will identify fraud and abuse vulnerabilities in electronic health records (EHR) systems as articulated in literature and by experts to determine how certified EHR systems address these vulnerabilities.” The agency did not provide further details of its review. 

The economics of switching to electronic health records is receiving new scrutiny in the wake of the Center for Public Integrity’s “Cracking the Codes” series, which found that thousands of medical professionals have steadily billed higher rates for treating seniors on Medicare over the last decade — adding $11 billion or more to their fees. The investigation suggested that Medicare billing errors and abuses are worsening as doctors and hospitals switch to electronic health records. A similar report was subsequently published by the New York Times.

The nation’s top health information technology official has launched an internal review to determine if electronic health records are prompting some doctors and hospitals to overbill Medicare.

Dr. Farzad Mostashari, the Obama administration’s National Coordinator for Health Information Technology, said in an interview Monday afternoon that his policy-setting committee of experts would examine the issue and make recommendations on how to address it. 

It is the second government action in the wake of the Center for Public Integrity’s “Cracking the Codes” series, which found that thousands of medical professionals have steadily billed higher rates for treating seniors on Medicare over the last decade — adding $11 billion or more to their fees.

The Center’s year-long investigation, published in September, suggested that Medicare billing errors and abuses are worsening as doctors and hospitals switch to electronic health records. A similar report was subsequently published by the New York Times.

Mostashari said he wants to find out if the digital systems are triggering higher billing codes by allowing doctors to cut and paste records from prior encounters with a patient, a practice known as “cloning.” Many experts say that this process can raise the size of a patient’s bill, even though it reflects little in the way of added or necessary medical service.

“If we are just copying the same information over and over, that’s not good medicine,” Mostashari said. “I’ve asked the policy committee to provide guidance on that.”

Mostshari also said that he wanted to determine if some software functions that do little more than prompt doctors to inflate the size of their bills “should be off limits.”
