What To Do When Your Doctor Fails To Doctor?
Not everyone loves their job. Not everyone has a job. Not everyone does their job. And that includes doctors and lawyers. Not all doctors and lawyers do their jobs well. When a doctor fails to doctor, where does the liability lie? On the facility? On the hospital?
That is exactly what happened in one of my cases. My client, an inpatient substance abuse facility, hired a physician. Upon hire, the doctor signed an employment agreement that stated that he or she would perform the role as a doctor/medical director for the facility. Years passed. There were no complaints, so the executive committee was under the impression that the doctor was fulfilling his duties. The members certainly had no reason to suspect that the doctor was not doctoring according to the employment contract. No, they assumed that a doctor would doctor.
Then a RAC audit happened. As you are well aware, RAC audits go back three years. The facility received a Tentative Notice of Overpayment from the RAC alleging the facility owed almost $10 million. I was hired, and I conducted a review of the facility, its policies, and interviewed all staff. It came to light that the doctor did not review the results of urinalysis tests. Remember, this is a substance abuse facility. Urine tests are essential. The Medicaid recipients provided the samples; they peed in a cup. The labs were ordered. The doctor has a standing order for definitive and presumptive urinalysis tests. The doctor has sole access to the test results electronically. We discovered, much to our horror, that the doctor never looked at the results. For the past three years, she has never informed any patient that they were or were not positive or negative for any substance. In my mind, reviewing the urinalysis results goes hand in hand with substance abuse therapy.
Here, we discovered a breakdown in the facility, but that breakdown was one person not doing his or her job. Sadly for him or her, we – the facility – were able to use the doctor’s failure to doctor to our advantage. We appealed the $10 million alleged overpayment. Our primary defense was throwing the doctor under the bus, and we had every right to do so. Who would have expected your medical director failing to direct or review pertinent tests. In the world of law, respondeat superior, normally, is the general rule. In Latin, respondeat superior means that the superior or the boss or the owner is responsible for those underneath them. In this case, the facility is the superior and the doctor is the inferior, so you would expect the facility to bear any liability of its employees. But, not here. Not in this case. The doctor failed to meet expectations of the job. By not reviewing urinalysis test results, the doctor veered enough off the track to relieve liability from the facility. The doctor’s inactions were the direct cause of the accusation of owing $10 million. The administrative law judge (“ALJ”) agreed. After terminating the doctor, we contemplated suing the physician for damages. However, since we won the alleged overpayment case, we did not do so.
Recoupment, Recoupment, Everywhere and Not a Drop to Keep
The Rime of the Ancient Mariner, a poem written by Samuel Coleridge, states “Water, water everywhere, nor any drop to drink.” It is a tale of retribution. The poem talks about a mariner who is traveling with his fellow sailors. Suddenly, when the mariner finds an albatross chasing them, the mariner at once kills the albatross in cold blood without any major reason. After the killing of the bird, nothing goes well with the mariner. He is not in a position even to hold communion with God. Killing an albatross is symbolic of showing a criminal disregard for a creature of nature.
Now, imagine the mariner is a Medicare or Medicaid auditor. You are the albatross. According to Coleridge, an auditor that needlessly and mindlessly accuses you of owing $1 million in alleged overpayments should suffer dire consequences. However, unlike in poetry, the auditors suffer nothing. The albatross may or may not perish. A health care company may or may not go bankrupt due to the mariner/auditor’s inane actions.
I have a case right now that the auditor applied the 1995 AND 1997 guidelines, instead of only the 1995 or 1997 guidelines. The auditor created a more rigid criteria than what was actually required. Not ok.
So, how do you stop recoupment when you are accused of owing money for allegedly improperly billing Medicare or Medicaid?
- Hire an attorney as soon as you receive a Tentative Notice of Overpayment (“TNO”). Do not do, what multiple clients of mine have done, do not wait until the last few days of being allowed to appeal the TNO until you contact an attorney. You want your attorney to have time on his or her side! And yours!
- Appeal timely or recoupment will begin. If you do not appeal, recoupment will occur.
- Start putting money aside to pay for attorneys’ fees. I hate saying this, but you are only as good (legally) as what you can pay your attorneys. Attorneys have bad reputations regarding billing, but in a situation in which you are accused of owing mass amounts of money or, in the worst case scenario, of fraud against Medicare, you want an experienced, specialized attorney, who understands Medicare and Medicaid. Note: You do not need to hire an attorney licensed or located in your State. Administrative Law Courts (where you go for Medicare and Medicaid legal issues) do not require the attorneys to be legally licensed in the State in which they are practicing. At least, most States do not require attorneys to be licensed in the State in which they are practicing. There are a few exceptions.
- Meditate. The process is tedious.
Warning for Acute Care Hospitals: You’re a Target for Overpayment Audits
Today I want to talk about upcoming Medicare audits targeted toward Acute Care Hospitals.
In September 2022, OIG reported that “Medicare Part B Overpaid Critical Access Hospitals and Docs for Same Services.” OIG Reports are blinking signs that flash the future Medicare audits to come. This is a brief blog so be sure to tune in on December 8th for the RACMonitor webinar: Warning for Acute Care Hospitals: You’re a Target for Overpayment Audits. I will be presenting on this topic in much more depth. It is a 60-minute webinar.
For OIG’s report regarding the ACHs, OIG audited 40,026 Medicare Part B claims, with half submitted by critical access hospitals and the rest submitted by health care practitioners for the same services provided to beneficiaries on the same dates of service (“DOS”). OIG studied claims from March 1, 2018, to Feb. 28, 2021, and found almost 100% noncompliance, which constituted almost $1million in overpayments to providers.
According to the OIG Report, CMS didn’t have a system to edit claims to prevent and detect any duplicate claims, as in the services billed by an acute hospital and by a physician elsewhere. Even if the physician reassigned his/her rights to reimbursement to the ACH.
As you know, a critical access hospital cannot bill Part B for any outpatient services delivered by a health care practitioner unless that provider reassigns the claim to the facility, which then bills Part B. However, OIG’s audit found that providers billed and got reimbursed for services they did perform but reassigned their billing rights to the critical access hospital.
The question is – why did the physicians get reimbursed even if they assigned their rights to reimbursement away? At some point, CMS needs to take responsibility as to the lack having a system to catch these alleged overpayments. If the physicians were reimbursed and had no reason to know that they were getting reimbursed for services that they assigned to an ACH, there is an equitable argument that CMS cannot take back money based on its own error and no intent by the physician.
On a different note, I wanted to give a shout out to ASMAC, which is the American Society of Medical Association Counsel; Attorneys Advocating for America’s Physicians. It is comprised of general counsels (GCs) of health care entities and presidents of State Medical Societies. ASMAC’s topics at conferences are cutting-edge in our industry of defending health care providers, interesting, and on-point by experts in the fields. I was to present there last week in Hawaii on extrapolations in Medicare and Medicaid provider audits. Thankfully, all their conferences are not in Hawaii; that is too far of a trip for someone on the East Coast. But you should look into the association, if ASMAC sounds like it would benefit you or you could benefit them, join.
Absent Auditors in Medicare Provider Appeals
(On a personal note, I apologize for how long since it has been my last blog. I was in an accident and spent 3 days in the ICU.)
I’d like to write today about the sheer absurdity about how these RAC, ZPIC, MAC, and other types of audits are being held against health care providers. When an auditor requests documents from a provider and opines that the provider owes a million dollars in alleged overpayments, I would expect that the auditor will show up before an independent tribunal to defend its findings. However, for so many of these Medicare provider appeals, the auditor doesn’t appear to defend its findings.
In my opinion, if the entity claiming that you owe money back to the government does not appear at the hearing, the provider should automatically prevail. A basic legal concept is that the accused should be able to confront its accuser.
I had depositions the last two weeks for a case that involved an opiate treatment program. The two main accusers were Optum and ID Medicaid. When Optum was deposed, they testified that Optum did not conduct the audit of the facility. When ID Medicaid was deposed, it contended that Optum did conduct the audit at issue.
When not one person can vouch for the veracity of an audit, it is ludicrous to force the provider to pay back anything. Auditors cannot hide behind smoke and mirrors. Auditors need to testify to the veracity of their audits.
To poke holes in Medicare audits, you need to know the rules. You wouldn’t play chess without knowing the rules. Various auditor have disparate look-back period, which is the time frame the auditor is allowed to look back and review a claim. For example, RACs may only look back 3 years. Whereas ZPICs have no specific look back period, although I would argue that the older the claim, the less likely it is to be recouped. There is also the federal 48-month limit to look backs absent accusations of fraud.
When appealing the outcome of a MAC or RAC audit, it is necessary for providers to have a specific reason for challenging the auditors’ determinations. Simply being dissatisfied or having generalized complaints about the process is not enough. Some examples of potential grounds for challenging a MAC or RAC determination on appeal include:
- Application if inapplicable Medicare billing rules
- Misinterpretation of applicable Medicare billing rules
- Reliance on unsound auditing methodologies
- Failure to seek an expert opinion
- Ignoring relevant information disclosed by the provider
- Exceeding the MAC’s or RAC’s scope of authority
It is imperative that you arm yourself in defending a Medicare audit, but if the auditor fails to appear at any stage in litigation, then you should call foul and win on a “absent” technicality.
Defenses Against Medicare/caid Audits: Arm Yourself!
Auditors are overzealous. I am not telling you anything you don’t know. Auditors cast wide nets to catch a few minnows. Occasionally, they catch a bass. But, for the most part, innocent, health care providers get caught in the overzealous, metaphoric net. What auditors and judges and basically the human population doesn’t understand is that accusing providers of “credible allegations of fraud” and alleged overpayments, when unfounded, has a profound and negative impact. First, the providers are forced to hire legal counsel at an extremely high cost. Their reputations and names get dragged through the mud because providers are guilty until they are proved innocent. Then, once they prove that there is no fraud or noncompliant documents, the wrongly accused providers are left with no recourse.
The audits generally result in similar reasoning for denials. For instance,
- Lacks medical necessity. Defense: The treating physician rule. Deference must be given to the treating physician, not the desk reviewer who has never seen the patient.
- Canned notes: Defense: While canned notes are not desirable, it is not against the law. There is no statute, regulation, or rule against canned notes. Canned notes are just not best practices. But, in reality, when you serve a certain population, the notes are going to be similar.
- X-rays tend to be denied for the sole reason that there are no identifying notes on the X-ray. Or the printed copy of the X-ray you submit to the auditors is unreadable. Defense/Proactive measure: When you submit an X-ray, include a brief note as to the DOS and consumer.
- Signature illegible; therefore, no proof of provider being properly trained and qualified. Defense: This one is easy; you just show proof of trainings, but to head off the issue, print your name under your signature or have it embedded into your EHR.
- Documentation nitpicking. The time, date, or other small omissions result in many a denial. Defense: There is no requirement for documents to be perfect. The SSA provides defenses for providers, such as “waiver of liability” and “providers without fault.” The “waiver of liability” defense provides that even if payment for claims is deemed not reasonable and necessary, payment may be rendered if the provider did not know and could not have been reasonably expected to know that payment would not be made.
Whenever a client tells me – let’s concede these claims because he/she believes the auditors to be right, I say, let me review it. With so many defenses, I rarely concede any claims. See blog for more details.
New Report Points to More Audits of Hospitals
Hospitals across the nation are seeing lower profits, and it’s all because of a sudden, tsunami of Medicare and Medicaid provider audits. Whether it be RAC, MAC, UPIC, or Program Integrity, hospital audits are rampant. Billing errors, especially ‘supposed bundling,’ are causing a high rate of insurance claims denials, hurting the finances of hospitals and providers.
A recent report from American Hospital Association (AHA) found “Under an optimistic scenario, hospitals would lose $53 billion in revenue this year. Under a more pessimistic scenario, hospitals would lose $122 billion thanks to a $64 billion decline in outpatient revenue”*[1]
The “Health Care Auditing and Revenue Integrity—2021 Benchmarking and Trends Report” is an insider’s look at billing and claims issues but reveals insights into health care costs trends and why administrative issues continue to play an outsize role in the nation’s high costs in this area. The data used covers 900+ facilities, 50,000 providers, 1500 coders, and 700 auditors – what could go wrong?
According to the report,
- 40% of COVID-19-related charges were denied and 40% of professional outpatient audits for COVID-19 and 20% of hospital inpatient audits failed.
- Undercoding poses a significant revenue risk, with audits indicating the average value of underpayment is $3,200 for a hospital claim and $64 for a professional claim.
- Overcoding remains problematic, with Medicare Advantage plans and payers under scrutiny for expensive inpatient medical necessity claims, drug charges, and clinical documentation to justify the final reimbursement.
- Missing modifiers resulted in an average denied amount of $900 for hospital outpatient claims, $690 for inpatient claims, and $170 for professional claims.
- 33% of charges submitted with hierarchical condition category (HCC) codes were initially denied by payers, highlighting increased scrutiny of complex inpatient stays and higher financial risk exposure to hospitals.
The top fields being audited were diagnoses, present on admission indicator, diagnosis position, CPT/HCPCS coding, units billed, and date of service. The average outcome from the audits was 70.5% satisfactory. So, as a whole, they got a ‘C’.
While this report did not in it of itself lead to any alleged overpayments and recoupments, guess who else is reading this audit and salivating like Pavlov’s dogs? The RACs, MACs, UPICs, and all other alphabet soup auditors. The 900 facilities and 50,000 health care providers need to be prepared for audits with consequences. Get those legal defenses ready!!!!

Medicare/caid Contracts: When the Contract Can Benefit the Provider
Today I pose a very important question for you. Do your participation contracts that you sign with Medicare/caid, MCOs, MACs – do they even matter? Are these boilerplate contracts worth the ink and the paper? The answer is yes and no. To the extent that the contracts are written aligned with the federal and State regulations, the contracts are enforceable. To the extent that the contracts violate the federal regulations, those clauses are unenforceable. The contract can even, at times, be more stringent or contain more limitations than the federal regulations. One thing is for sure, these contracts can be your worst enemy or your savior, depending on the clauses.
An Idaho client-provider of mine has been the victim of Optum-“black-hole-ism.” In this case, the “black-hole-ism” will save my client from paying $500k it does not owe. My client is the leading substance abuse (SA) provider in Idaho. Optum is managing Medicaid dollars, which makes it the Agent of the “single State agency,” the Department of Health of Idaho. 42 C.F.R. 431.10. See blog.
The Optum provider contract states that – “It is agreed that the parties knowingly and voluntarily waive any right to a Dispute if arbitration is not initiated within one year after the Dispute Date.” What a great clause. If only all contracts had this limiting clause.
In our dispute, Optum avers we owe $500k. The first demand we received was dated December 2018 for DOS 2016-2017. Notice Optum was timely back in 2018. That was when the client hired my team, and we submitted a rebuttal and initiated the informal appeal to Optum. Here’s where Optum gets sloppy. Months pass. A year passes. I hear crickets in the background. A year and a half passes. Who knows why Optum took a year and a half to respond? COVID happened. Black-hole-ism? Bureaucracy and red tape? Apathy? Ineptness?
Finally, we get a response in September 2020. We respond in October 2020. Our new response included a novel argument that was not included in the 2018 rebuttal. Our argument went something like: “Na Na Na Boo Boo, you’re too late per 7.1 Optum contract.” If we could have included a raspberry, we would done so.
Remember the clause? “It is agreed that the parties knowingly and voluntarily waive any right to a Dispute if arbitration is not initiated within one year after the Dispute Date.”
Well, 2020 is 3-4 years after the initial DOS at issue: 2016-2017. This time, the boilerplate contract is our friend.
Since there is also an arbitration clause, which is not your friend, we will be wholly dependent on an arbitrator to interpret the one-year, limiting clause as a logical, reasonable person. But I will be shocked if even an arbitrator doesn’t throw out this case with prejudice.
Take Medicare or Medicaid? Why You Should Have an Attorney on Retainer
They say that lightning never strikes the same place twice, but tell that to my colleague Bill. Bill has been struck by lightning twice and has lived to tell the story. Granted, he was not physically standing in the same place that he was struck the first time as when he was hit by lightning the second time – so lightning technically didn’t hit the same place twice. But it did strike the same person twice. Maybe Bill is just extremely unlucky, or maybe Bill is extremely lucky because he lived through the incidents.
An intense shock can severely impair most of the body’s vital functions. Cardiac arrest is common. Yet Bill lived. Twice.
No one ever thinks they will get struck by lightning. But it happens. According to the National Weather Service, so far this year, lightning strikes have killed at least 20 people in the US, and that does not even take into consideration the people who were just injured, like my pal Bill.
A lightning strike is a massive electrical discharge between the atmosphere and an earth-bound object. A lightning bolt can heat the surrounding air to 50,000 degrees Fahrenheit—that’s five times hotter than the sun—and can contain up to 300kV of energy.
Yet most people do survive, in part because lightning rarely passes through the body.
Instead, a “flashover” occurs, meaning that the lightning zips over the body, traveling via ultra-conductive sweat (and often rainwater), which provides an external voltage pathway around the body. When people do die from a lightning strike, it is usually due to an electrical discharge-induced hear attack. A body hit by lightning will show various signs of trauma.
Like a gunshot, a lightning strike causes both an exit and entrance wound, marking where the current both entered and left the victim. Lichtenberg scarring, which outlines ruptured blood vessels, frequently covers the body in odd, almost beautiful, spiderweb patterns.
Surprisingly enough, many lightning strike survivors do not remember being struck. Instead, the only evidence of the traumatic event is burnt, displaced clothing and marks along the body.
For instance, many lightning strike survivors report memory issues, trouble with concentration and severe headaches, all of which last decades after the initial strike.
Due to the rarity of lightning strike cases, less time and resources have been devoted to better understanding how these strikes impact long-term brain function. An unpublished study by medical doctor Mary Ann Cooper found that there were “significant differences in brain activity between lightning-strike victims and healthy people as they performed mental-aptitude tests.”
Aside from impacting long-term brain function, lightning strikes are also known to blow out eardrums, prompting constant muscle twitches and moderate to severe nerve damage. Overall, the effects of a lightning strike may range from a slight inconvenience to a debilitating, lifelong struggle. In the case of my colleague, you would never be able to tell mind looking at him that he has been hit by lightning twice.
Why is this – extensive – discussion about lightning strikes relevant? – Or is it not?
If you are a health care provider and accept Medicare or Medicaid, the risk of an audit far exceeds your chances of getting struck by lightning. In FY 2016, CMS continued its use of the Affordable Care Act authority to suspend Medicare payments to providers during an investigation of a credible allegation of fraud. CMS also has authority to suspend Medicare payments if reliable information of an overpayment exists. During FY 2016, there were 508 payment suspensions that were active at some point during the fiscal year. Of the 508 payment suspensions, 291 new payment suspensions were imposed during FY 2016.
Medicare and Medicaid audits far exceed lightning strikes. Yet, providers believe in their heart of hearts that and on an audit (or an audit with bad results) will never happen to them, which causes providers to not engage in attorney until after the lightning strikes. Then it’s too late, and you have Lichtenberg scarring across your arm.
There is scene in Breaking Bad in which Saul, the attorney, stops a person from talking. He says, “Give me a dollar. Don’t tell me anything until you give me a dollar. Once money is exchanged, we will have attorney-client privilege.” What Saul was saying is that the exchange of money catalyzed the duty for Saul to keep all conversation confidential.
This was a low-point of legal-fiction television. It made great drama with zero accuracy.
The question is why should you have an attorney on retainer?
The obvious response is that you can have confidential conversations with said attorney at your beck and call. The honest truth is that you do not have to have an attorney on retainer in order for your conversations to be confidential. But is smart to do so, and I will tell you why.
If you call me and I have never represented you and you ask me a legal question, our conversation is legally protected, even if you hire a different attorney.
No – the reason to have an attorney on retainer is to be able to consult him or her with legal questions on a daily basis, and, especially of there is an ongoing audit. Most of my clients do not contact me when they receive the document request. They think, “Oh, this is no big deal. I will give my records to [state] or [federal] – [and/or its contractors] government and they will determine that my [Medicare] or [Medicaid] records are amazing. In fact the [state] or [federal] government my even ask me to educate other providers on what pristine records should look like. I got this. Easy, peasy, lemon-squeezey.” They contact me when they get an accusation of an alleged overpayment of $5 million. Lichtenberg scarring has already occurred.
The smartest clients contact me prior to receiving an alleged overpayment of $12 million or an accusation of fraud. They contact me the moment they receive a notice of an audit or a request for documents…before ever submitting documents to the government.
Because, regardless the type of provider, be it dentist, behavioral counseling, podiatrist, chiropractor, or hospital, understand that every communication with a government auditor and/or contractor is admissible in court – if the communication does not go through an attorney. When the [state/federal] auditor asks to see a record and you say, “Let me get it from my off-site storage facility” – BAM – HIPAA violation. When the state/federal auditor asks to see a record and you say, “Here it is,” and fail to keep a copy for yourself, there can be discrepancy in the future as to what you actually provided. And you are in a “he said she said” battle – never good.
On the other hand, if you have an attorney on retainer, you can ask any question you need, you can get any advice you desire, and it’s all confidential. It is as though you have Siri in your back pocket. It’s the 411 for legal information. It’s an ATM for legal advice. AND it is all confidential.
Next time you think to yourself, “Self, I will ace any Medicaid or Medicare audit. I don’t need counsel. I can talk to the auditors myself without an attorney. I got this.”
Think again. [Don’t, necessarily, call Saul, but call someone.] Because, like lightning strike victims, you may not even remember the audit. Until you are scarred.
Medicare and Medicaid RAC Audits: How Auditors Get It Wrong
Here is an article that I wrote that was first published on RACMonitor on March 15, 2018:
All audits are questionable, contends the author, so appeal all audit results.
Providers ask me all the time – how will you legally prove that an alleged overpayment is erroneous? When I explain some examples of mistakes that Recovery Audit Contractors (RACs) and other health care auditors make, they ask, how do these auditors get it so wrong?
First, let’s debunk the notion that the government is always right. In my experience, the government is rarely right. Auditors are not always healthcare providers. Some have gone to college. Many have not. I googled the education criteria for a clinical compliance reviewer. The job application requires the clinical reviewer to “understand Medicare and Medicaid regulations,” but the education requirement was to have an RN. Another company required a college degree…in anything.
Let’s go over the most common mistakes auditors make that I have seen. I call them “oops, I did it again.” And I am not a fan of reruns.
- Using the Wrong Clinical Coverage Policy/Manual/Regulation
Before an on-site visit, auditors are given a checklist, which, theoretically, is based on the pertinent rules and regulations germane to the type of healthcare service being audited. The checklists are written by a government employee who most likely is not an attorney. There is no formal mechanism in place to compare the Medicare policies, rules, and manuals to the checklist. If the checklist is erroneous, then the audit results are erroneous. The Centers for Medicare & Medicaid Services (CMS) frequently revises final rules, changing requirements for certain healthcare services. State agencies amend small technicalities in the Medicaid policies constantly. These audit checklists are not updated every time CMS issues a new final rule or a state agency revises a clinical coverage policy.
For example, for hospital-based services, there is a different reimbursement rate depending on whether the patient is an inpatient or outpatient. Over the last few years there have been many modifications to the benchmarks for inpatient services. Another example is in behavioral outpatient therapy; while many states allow 32 unmanaged visits, others have decreased the number of unmanaged visits to 16, or, in some places, eight. Over and over, I have seen auditors apply the wrong policy or regulation. They apply the Medicare Manual from 2018 for dates of service performed in 2016, for example. In many cases, the more recent policies are more stringent that those of two or three years ago.
- A Flawed Sample Equals a Flawed Extrapolation
The second common blunder auditors often make is producing a flawed sample. Two common mishaps in creating a sample are: a) including non-government paid claims in the sample and b) failing to pick the sample randomly. Both common mistakes can render a sample invalid, and therefore, the extrapolation invalid. Auditors try to throw out their metaphoric fishing nets wide in order to collect multiple types of services. The auditors accidentally include dates of service of claims that were paid by third-party payors instead of Medicare/Medicaid. You’ve heard of the “fruit of the poisonous tree?” This makes the audit the fruit of the poisonous audit. The same argument goes for samples that are not random, as required by the U.S. Department of Health and Human Services (HHS) Office of Inspector General (OIG). A nonrandom sample is not acceptable and would also render any extrapolation invalid.
- A Simple Misunderstanding
A third common blooper found with RAC auditors is simple misunderstandings based on lack of communication between the auditor and provider. Say an auditor asks for a chart for date of service X. The provider gives the auditor the chart for date of service X, but what the auditor is really looking for is the physician’s order or prescription that was dated the day prior. The provider did not give the auditor the pertinent document because the auditor did not request it. These issues cause complications later, because inevitably, the auditor will argue that if the provider had the document all along, then why was the document not presented? Sometimes inaccurate accusations of fraud and fabrication are averred.
- The Erroneous Extrapolation
Auditors use a computer program called RAT-STATS to extrapolate the sample error rate across a universe of claims. There are so many variables that can render an extrapolation invalid. Auditors can have too low a confidence level. The OIG requires a 90 percent confidence level at 25 percent precision for the “point estimate.” The size and validity of the sample matters to the validity of the extrapolation. The RAT-STATS outcome must be reviewed by a statistician or a person with equal expertise. An appropriate statistical formula for variable sampling must be used. Any deviations from these directives and other mandates render the extrapolation invalid. (This is not an exhaustive list of requirements for extrapolations).
- That Darn Purple Ink!
A fifth reason that auditors get it wrong is because of nitpicky, nonsensical reasons such as using purple ink instead of blue. Yes, this actually happened to one of my clients. Or if the amount of time with the patient is not denoted on the medical record, but the duration is either not relevant or the duration is defined in the CPT code. Electronic signatures, when printed, sometimes are left off – but the document was signed. A date on the service note is transposed. Because there is little communication between the auditor and the provider, mistakes happen.
The moral of the story — appeal all audit results.
