The Center for Public Integrity

Medical professionals who cheat Medicare by billing for more complex and costly services than they deliver threaten to drain the elderly health-care program’s already shaky finances, Sen. Charles Grassley said Thursday.

The Iowa Republican’s comments came in reaction to The Center for Public Integrity’s “Cracking the Codes”  series published this week. The investigation 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.

Grassley called the findings “disturbing,” though “not surprising” because any time Medicare creates a new payment structure, “a cottage industry develops to teach providers how to maximize revenue in the system.” 

The Center’s year-long examination  uncovered a variety of costly billing errors and abuses that have plagued Medicare for years—from confusion over how to pick proper payment codes to outright overcharges. The findings also suggest the problems are worsening as doctors and hospitals switch to electronic health records.

 Medicare pays doctors for office visits using five escalating payment codes, which range from a minimal visit of about five minutes time for about $20 to about $140 paid for more complex treatments that generally take 40 minutes or more of face-to-face time with the doctor. Federal officials expect a medical practice to report a range of the five codes because some patients require more time and effort to treat than others. Medicare uses the scales to pay for more than 200 million office visits each year and other doctor services that cost taxpayers more than $33 billion.

Eleven years ago, Dr. Kathryn Locatell’s testimony at a U.S. Senate hearing on alleged Medicare billing abuses generated a rush of media coverage, but little lasting reform.

Locatell, a California physician, helped expose medical billing consultants who made a living teaching doctors how to use the billing system to reel in higher fees.

The techniques ranged from billing for medical treatments that weren’t needed to packing a patient’s file with irrelevant details as a means to justify higher, more lucrative, Medicare billing codes.

“The information presented to us at the seminars did not include any method of … ensuring that the services billed for were medically necessary,” Locatell testified at the June 2001 Senate Finance Committee hearing.

Despite much legislative hand-wringing and media attention — CBS Evening News told her story prominently — little changed in the aftermath of the congressional probe.

More than a decade later, federal officials are still struggling to make sure doctors code accurately and charge Medicare only for treatments that are medically necessary, a Center for Public Integrity investigation has found.

The Center’s analysis of Medicare billing records found that more than 7,500 doctors billed the two top paying codes for three out of four office visits, a sharp rise from the start of the decade. Government records also show medical professionals billing billions of dollars in suspect payments in recent years through coding errors.

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.

The “Cracking the Codes” stories are but the latest in a series of Center pieces that illuminate questionable Medicare practices and policies by marrying traditional shoe-leather reporting with rigorous data analysis.

The foundation of these pieces is the Center’s access to about two terabytes of Medicare claims data — data that was obtained by the Center in 2010 as the result of a settlement from litigation against the Centers for Medicare and Medicaid Services.   

Delving deeply into this data has now helped us expose one of medicine’s dirty little secrets: medical providers garnering extra Medicare fees by “upcoding,” or billing for more extensive care than had actually been delivered. But it wasn’t easy. “Cracking the Codes” is the result of almost 20 months of often-tedious work.

That work began in early 2011, with preliminary analysis by data editor David Donald that summarized changes in hundreds of codes used by doctors and hospitals to bill Medicare over much of the past decade. Center investigative reporter Fred Schulte spent hours sifting those findings for story ideas, and subsequently discovered sharp spikes in higher-cost Medicare billing codes for routine patient visits to doctors. The code patterns indicated that short office visits paying doctors modest amounts had dropped off precipitously, while lengthier and higher-paid visits were rising dramatically. The trends ran counter to much of the medical research; the differences were costing taxpayers billions of dollars. 

Under Donald’s direction, former Center data analyst Elizabeth Lucas then embarked on a six-month journey through millions of Medicare records to determine the extent of the billing anomalies and  quantify the cost to taxpayers. The database was daunting indeed, consisting of scores of tables and thousands of columns, totaling more than 700 million claims.
