Upcoding is in the eye of the beholder

There was an interesting and important article in the NY Times the other day about the gradual increase in the average E/M coding levels used by doctors over the last few years. For the non-docs, med students and ER trainees out there, here is a brief summary of the way physician billing works in the ER:

During and after the patient encounter, the physician creates a medical record. This is a pretty standardized document including the history the doctor got from the patient, the exam, any tests and the medical decision-making. And, of course, the diagnosis. This gets reviewed, typically, by a professional coder who then applies Medicare's rules to determine what level of complexity the service was, and the associated cost of that service. (In some cases, the doctors code their own charts, and some are automatically coded by a computer, but both of these are exceptions to the rule.) ER visits are coded on a 5-level scale, with a Level 1 (99281) being the simplest and a Level 5 being the most intense. These are called E/M codes because they refer to the "Evaluation and Management" of the case, as opposed to, say, a surgical procedure.

The amount Medicare pays the doctor for an E/M code in the ER ranges from about $20 to $175. (If you've ever received a multi-thousand-dollar ER bill, chances are good that was the hospital bill. The physician's fees are much more modest in most cases.

Medicare, of course, tracks utilization and recently published a report (PDF Link) about the recent trends in the doctors' use of the codes. What they found is that over the last decade, we have shifted from using the lower codes and towards the higher ones:


This is where it gets interesting. The feds and some consumer watchdogs view this trend as clear evidence of fraud and abuse, that the physicians are "upcoding" the visit levels to increase their income. On the other hand, I've spent the last decade trying to educate physicians on how to document the patient encounter so that you can accurately capture the legitimate value of the service provided. So I look at that trend and think to myself "Job well done."

From the perspective of a practicing physician, the rules that govern the documentation required to capture a service level are deliberately onerous and designed to produce downcodes. They require the doc to collect far more data than is actually necessary based on the actual condition of the patient. You forget to check one box, you leave out one required element, and despite the complexity, gravity and risk of a patient's condition, you will not be paid for the service. For years, we have been losing money to these archaic rules (they date from 1995), and we have been struggling to stem the leakage of revenue from our practices.

The industry responded to these rules by developing tools to comply with them. The first thing was to have professional coders. Prior to 2000, a substantial majority of ER charts were hand-coded by the physician; now that is quite rare. Then we got templated paper records which prompted the docs to get all the required data points. Now we have EMRs which do the same thing more efficiently. It's no surprise that as an industry we have gotten better at meeting the guidelines.

And then there is the fact that the ER is a different place than it was in 2000. Our patients are older and sicker. We do more in the ER than was true in the past. Patients are rarely directly admitted any more, but rather get the majority of their admitting workup done in the ER. I don't know how much of the skew in the above graph is due to these factors, but they shouldn't be disregarded.

But I don't like where this is going. The government is desperate, understandably, to save money on healthcare expenditures. They seem to have assumed their conclusion that the increased coding levels is fraudulent and unjustified, and there seem to be few voices disagreeing with them. Furthermore, there is some inappropriate upcoding, and it's very easy for a patient with an egregious bill or a certain physician (or group) who pushed the envelope too far to be held up as anecdotal proof that doctors are all a bunch of thieves.

The article quotes some insurers as saying that nearly half of the charges being submitted are "upcodes," without noting that the insurers have a vested interest in not paying and may not be presenting an honest picture of the claims. We had a run-in with a certain national insurer who analyzed a few hundred claims, found that 80% of them were upcoded and demanded a couple of million dollars in restitution. We fought back, of course, defended each chart on the merits of the care, and established that in fact 97% of the time the correct, higher, code was appropriately used. That the insurers are not necessarily honest players here passes unremarked.

I think changes are coming, and it worries me. We already have one insurer saying that they simply won't pay for cloned records — but how will they tell if a chart has been cloned? Do charts have DNA? I think what we are going to see is the carriers becoming very aggressive in arbitrarily denying payment or demanding restitution. I would love to see revised and streamlined coding rules to replace the old ones, but I suspect that if that were to happen, the new rules will be designed to be more restrictive and more burdensome.

Just go to the ER, redux


Sweet Breakdancing Jeebus, we are back to this:

Downplaying the need for the government to ensure that every person has health insurance, Mitt Romney on Sunday suggested that emergency room care suffices as a substitute for the uninsured. 
"Well, we do provide care for people who don't have insurance," he said in an interview with Scott Pelley of CBS's "60 Minutes" that aired Sunday night. "If someone has a heart attack, they don't sit in their apartment and die. We pick them up in an ambulance, and take them to the hospital, and give them care."

If this quote sounds familiar, it was previously uttered, near word for word, by the intellectual giant who was the standard bearer of the Republican party for most of the last decade, George W Bush (remember him?). He said, in 2007:
"The immediate goal is to make sure there are more people on private insurance plans. I mean, people have access to health care in America," he said. "After all, you just go to an emergency room."
I was going to expound on my long-held point that "Just go to the ER" is not a substitute for national health policy, and that the ER is unable to provide comprehensive and preventative care yadda yadda yadda but fuck it. You all know that already. I can't stand it. I'm gonna go have a drink instead.
