Don’t Take ZPIC or RAC Extrapolation Calculations at Face Value – Can Their Results Be Readily Reproduced?

(July 14, 2010): Imagine a ZPIC, PSC, or RAC handing you a claim analysis rife with alleged errors, an indecipherable list of statistical formulae, and an extrapolated recovery demand that will cripple your practice or clinic.  What steps should you take to analyze their work?  Based on our experience, providers can and should carefully assess the contractor’s actions, use of formulas and application of the RAT-STAT program when selecting a statistical sample and extrapolating the alleged damages based on the sample pulled.  Over the years, we have challenged the extrapolation of damages conducted by Medicare contractors around the country, covering tens of thousands of claims.  Regardless of whether you are providing Partial Hospitalization, Evaluation and Management, Home Health, Physical Therapy, Surgical or other services, it is imperative that you work with experienced legal counsel and statistical experts to analyze the statistical sampling and extrapolation steps taken by the contractor. Should you succeed in invalidating the extrapolation, the whole games changes.  The question is – “How can you go about fighting an extrapolation calculation?”

One method is to show that the contractor’s auditor failed to identify a Statistically Valid Random Sample (SVRT).  Among the first steps is you should take is to retain experienced legal counsel to review the Medicare contractor’s actions.  Notably, there are a multitude of legal arguments which may be asserted (depending on the specific facts in your case).  Our firm has worked with several outstanding statistical experts over the years, each of which has a proven track record of analyzing the contractor’s actions and identifying any flaws made by the ZPIC or PSC when extrapolating damages.

Notably, Section 3.10.4.2 of CMS’ Medicare Program Integrity Manual establishes that the contractor is obligated to fully document the statistical methods an auditor employs:

“The PSC or ZPIC BI [Benefit Integrity] unit or the contractor MR [Medical Review] unit shall identify the source of the random numbers used to select the individual sampling units. The PSC or ZPIC BI unit or the contractor MR unit shall also document the program and its algorithm or table that is used; this documentation becomes part of the record of the sampling and must be available for review.” (emphasis added)

“The PSC or ZPIC BI units or the contractor MR units shall document all steps taken in the random selection process exactly as done to ensure that the necessary information is available for anyone attempting to replicate the sample selection.” (emphasis added)

ZPIC and PSC statisticians must be able show their work to the extent that a reviewer can attempt to “replicate” their actions and determine whether or not the steps taken were consistent with accepted principles and practices of statistical sampling.  The failure of a ZPIC or PSC statistician to fully and properly document his actions may serve as the basis for seeking to invalidate the extrapolation. The calculation of a valid statistical sample and the extrapolation of damages by ZPIC and PSC statistician is a highly complex process. After handling many extrapolated damages cases, we have found that few ZPIC or PSC statisticians fully meet their obligations to document the steps taken and / or conduct the process in a proper fashion, consistent with accepted statistical sampling procedures.  Should your practice or clinic find that it is facing an extrapolated Medicare audit, it is strongly recommended that you engage qualified, experienced counsel to represent you in the process.  Your legal counsel can then engage a qualified statistician to assess the contractor’s actions.

A Look at RACs — Part III: What Should Physicians and other Medicare Providers Know about Appeals and Recoupment?

(July 2, 2010):  CMS’ Recovery Audit Contractor (RAC) program is now permanent and nationwide.  As we discussed in Part I of this series, while small providers were largely ignored during the demonstration program, physicians, home health, hospice, and durable medical equipment (DME) suppliers should be on the lookout for increased attention.  In Part II, we discussed some ways providers can prepare for and respond to an audit request.

In this Part III, we will discuss a provider’s appeal options in the event that a RAC identifies an alleged overpayment as a result of its audit.  It is important to remember that RACs are paid on a contingency fee basis and so are highly incentivized to seek out overpayment errors.

CMS’ enthusiastic trumpeting of the RAC demonstration program results seems to ignore the RACs’ reputation for overly aggressive auditing.  Indeed, a June 2010 CMS program update reveals that, when providers chose to appeal a RAC determination, providers won 64.4% of the time.  CMS has since implemented a requirement that the RAC remit its contingency fee if its audit determination is overturned at any level of appeal, not just the first level.  Whether this will improve RACs dismal win rate on appeal remains to be seen.

I.          What Are the Options to Appeal a RAC Determination of Overpayment?

First, providers that want to challenge the determination should be aware they have a  very limited period of time to file for redetermination appeal if they wish to avoid recoupment.  While a provider has 120 days to file for redetermination appeal, if they wait past day 30, the Medicare contractor (not the RAC) will initiate recoupment.  Additional information regarding recoupment is discussed below.

Appealing a RAC claims denial follows the uniform Medicare Part A and Part B appeals process.    The following deadlines are strictly adhered to.

Medicare Appeal Deadlines

Level	Stage	Reviewing Entity	Filing Deadline
1st	Redetermination	Medicare Administrative Contractor (MAC)	120 days of receiving notice of initial determination
2nd	Reconsideration	Qualified Independent Contract (QIC)	180 days of receiving notice of redetermination decision
3rd	Hearing	Administrative Law Judge (ALJ)	60 days of receipt of the QIC’s decision
4th	Administrative Review (HHS)	Medicare Appeals Council (MAC)	60 days of receipt of the ALJ’s decision
5th	Judicial Review	Federal District Court	60 days of receipt of the MAC’s decision

Our experience has shown that ALJs are honest brokers who are the most willing to hear arguments from providers.  While they will follow the law andapplicable coverage provisions, they tend to be much more thorough and consider the provider’s arguments in support of payment.  In many cases, this has been the first level that a fair and reasonable consideration of the evidence has occurred.

II.         What about Recoupment?

Notably, the deadlines above are filing deadlines only.  Medicare begins recouping funds well before the time frame for appeal has lapsed at each stage.  Medicare begins recouping funds only 30 days after the RAC’s initial determination and only 60 days after its redetermination decision.  This puts significant pressure on providers to file for first and second level appeals more rapidly than they otherwise might.  In later stages, recoupment cannot be stayed by filing the appeal.

Recoupment Timeframes
Day One – Initial Demand of a RAC Overpayment Determination	First Level Appeal	Second Level Appeal	Appeals to Administrative Law
The process begins when a Demand Letter, with appeal rights, is sent to Provider.  If there is no appeal and the provider does not remit the demanded amount, offset begins on day 41.	To avoid recoupment starting on day 41, the provider must request the 1st level appeal within 30 daysfrom the date of the Demand Letter.  If an appeal is received after day 30 and recoupment started on day 41, the recoupment process will stop on the remaining balance.	To avoid recoupment beginning or resuming after a Redetermination, the provider must submit the 2nd level appeal request to the QIC within 60 daysfrom the overpayment letter (if applicable) or from the decision letter.  If an appeal request is received after day 60, the recoupment process will stop on the remaining balance.	Limitation on recoupment ends after the 2nd level appeal.  Recoupment shall begin 30 days from the appeal decision and will continue until debt is satisfied, whether or not the provider appeals to the ALJ or subsequent levels.

Separate from and prior to the appeals process, a provider may rebut any proposed recoupment action within 15 days of the notice of impending recoupment.  A provider may issue a statement to the claims processing contractor providing evidence as to why the overpayment action should not take place.  This process does NOT provide an opportunity to review the medical documentation or the audit determination itself.

A Look at RACs — Part II: How Should Physicians and Other Providers Respond to a RAC Audit?

(June 29, 2010): In Part I of this series, we reacquainted you with the design and purpose of the now permanent Recovery Audit Contractor (RAC) Program.  Although RACs largely focused on inpatient care during CMS’ demonstration program, RACs are a real threat to small providers that don’t have the intensive compliance programs in place that most hospitals do.  In this Part II, we will look at how physicians, home health, hospice, and durable medical equipment (DME) suppliers can prepare for and respond to RAC audits.

Even if no demands are issued, the RAC audit process exposes providers to substantial risks and administrative costs.  Fortunately, both can be managed with thoughtful implementation of effective compliance measures and a well-planned response to an audit.

I.              How Should Physicians and Other Small Providers Prepare for a RAC Audit?

It is essential that the preparation for a RAC audit begins before the RAC ever knocks on the door.  Deadlines are tight and so physicians without effective compliance programs in place run the risk of claims being denied simply because they can’t show that they crossed all the “T’s” and dotted the “I’s” in time.

Physicians, home health, hospice, and DME suppliers can begin to target their compliance efforts by examining the reasons for denials issued during the recently concluded RAC demonstration program.  During the course of that program, of improper payments identified,

• 35% were the result of incorrect coding;
• 8% were the result of insufficient documentation (including failure to submit information on time or to submit enough information); and
• 17% were the result of other issues, such as basing claim payments on outdated fee schedules or duplicate claims.  Meanwhile,
• 40% were deemed medically unnecessary.

In other words, 60% of denied claims had nothing to do with patient care.  No one goes into health care to spend their time creating and perfecting paper trails but long experience with Medicare tells us that doing so cannot be avoided.

Thus, to prepare for a RAC audit, as a provider you can:

• Implement and continuously review your compliance plan;
• Review the documentation requirements for each item or service you provide;
• Maintain your files thoroughly and consistently;
• Do NOT rely on other suppliers or providers for record-keeping; and
• Make sure all your documentation is legible.

II.         How Should Physicians and Other Small Providers Respond to a RAC Audit?

The RAC audit process starts with a request for records, upon which the provider has a strictly enforced 45 days (plus mail time) to respond.  Upon receiving a request for records, providers can take several steps to protect yourselves:

• Take care before conducting an internal review of the claims requested.  While an internal analysis can be invaluable, you want to avoid creating a non-privileged paper trail of identified problems that could later be referred to law enforcement if a RAC makes a fraud referral.
• Review past claims audits and evaluations to determine whether the requested claims have been previously evaluated.
• Remember that filing deadlines are strictly enforced so calculate early on when appeals must be filed and begin to gather supporting documentation.
• Consider retaining an expert in extrapolation.
• Do NOT assume the contractor’s arguments are meritorious.  Carefully review Medicare policy to see if the RAC cited it correctly.
• Retain duplicates of any information that you submit to the RAC.

III.        Is Anything Different in the Permanent Program?

Small providers with experience being audited in the demonstration program should be on the lookout for the several changes implemented under the permanent program that may help protect them.  For instance,

• RACs’ Contractor Medical Directors are now required to speak with a provider regarding a claim denial, if requested, and a reviewer must provide credentials upon request.
• The reason for the review must be listed on a request for records letters and overpayment letters.
• The look-back period is reduced to 3 years from 4.
• CMS has set uniform limits on the number of records that can be requested in a 45 day period (sliding scale).

 More details concerning these and other changes to the permanent program can be found in the CMS RAC Demonstration Evaluation Report, available at https://www.cms.gov/RAC/02_ExpansionStrategy.asp.

A Look at RACs — Part I: What Do Physicians, Home Health, Hospice, and DME Providers Need to Know?

(June 25, 2010): The purpose of this series of articles is to assess the Recovery Audit Contractor (RAC) Program from the perspective of physicians, home health, hospice, durable medical equipment (DME) providers, and other relatively small Medicare providers.  As many non-hospital providers will acknowledge, early cries of wolf by law firms and consultants did a fine job of initially publicizing the RAC threat.  Unfortunately, the threat of a RAC audit now appears to be largely ignored by non-hospital providers due to the seemingly widespread sense that RACs will likely continue to focus their efforts on large, institutional Medicare providers – the ultimate “low hanging fruit” in terms of potential Medicare overpayments.

RACs are, in fact, a real threat to physicians and other small Medicare providers, despite the fact the contractors have passed over these providers in the past.

Over the last six weeks, the Centers for Medicare and Medicaid Services (CMS) has sponsored nationwide conference calls titled “Nationwide RAC 101 Call” specifically aimed at physicians, home health, hospices, and DME providers. Further, CMS conducted two general nationwide conference calls discussing the RAC program that were open to all Medicare providers.

These seemingly innocent informational calls were in fact extraordinarily significant, servicing almost as a “touchstone” for CMS and its RAC auditors.  With the completion of these nationwide teleconferences, outreach has now been completed and CMS can affirmatively state that these non-hospital providers have been given multiple opportunities to learn about the RAC program and prepare for a RAC audit.   All states are now eligible for review.

While CMS must still approve “issues” prior to their widespread review by the RACs, the contractors now have the billing data that they need to analyze and identify possible targets.

As physicians and other non-hospital providers prepare for possible audit, it is helpful to review hospitals’ experiences when preparing for and responding to a RAC audit.  On June 22, 2010, the American Hospital Association (AHA) released its findings that the RAC program is having a widespread impact on almost all hospitals, even though many have not even been subjected yet to a RAC audit.[1] In fact, for the first quarter of 2010 alone:

• 84% of responding hospitals reported that RACs impacted their organization;
• 49% of responding hospitals reported increased administrative costs; and
• 17% of the hospitals using external resources to address RACs hired consultants at an average cost of almost $92,000.

So, what do providers and non-hospital Medicare providers need to know about RACs?  This multi-part series will address the following:  First, the purpose and impact of RACs; Second, how to respond to RACs when they come calling; Third, some of the emerging issues for physicians and other small Medicare providers regarding RACs.

I. What’s a RAC?

The RAC program was created by Section 306 of the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA).  Operating under the direction of the Department of Health and Human Services (HHS), RACs are independent third-party contractors tasked with identifying and correcting improper past Medicare payments.  Each of four RACs has jurisdiction over a separate region of the United States.

After a three year demonstration in which RACs identified $1.03 billion in improper Medicare fee-for-service payments, the program became permanent earlier this year.  RACs join scores of other Medicare audit contractors.  CMS created the following table to clarify the role RACs are supposed to play compared to other contractors.[2] However, as we will see later in this series, these roles are not clearly delineated and the overlap in the review process can create substantial confusion and waste.

Role of Medicare Review Contractors
Improper Payment Function	Contractor Performing Function
Preventing future improper payments through pre-pay review and provider education	Medicare claims processing contractors
Detecting past improper payments	RACs
Measuring improper payments	CERT [Comprehensive Error Rate Testing]
Performing higher-weighted DRG [diagnosis related group] reviews and expedited coverage reviews	QIOs [Quality Improvement Organization]

RACs are highly incentivized to hunt for evidence of overpayments in high-cost categories of service and to needle out errors that have nothing to do with actual patient care. RACs are paid on a contingency basis so it stands to reason that, during the initial program demonstration, only 4% of improper payments identified were underpayments.  This “bounty hunter” approach also helps to explain why prior audits have focused almost exclusively on high-cost inpatient care services. Recent GAO testimony shed light on this situation and may cause RACs or other contractors to shift their focus to entities that do not have hospitals’ long history of review and compliance, namely physicians and other relatively small Medicare providers.  Finally, a substantial percentage of overpayments collected by RACs during the demonstration program resulted from preventable coding errors, countering the myth that CMS is primarily focused on weeding out unnecessary service claims.

Providers in Region C may want to consider that the AHA found hospitals in that region, encompassing nearly 40% of all U.S. hospitals including those in Texas, Florida, and Virginia, reported the highest number of medical records requested, the highest amount of dollars targeted in medical record requests, and the highest number of denied claims (47% of the $2.47 million in denied claims reported in the first quarter of 2010).

II. Are There Any Safeguards to Protect Physicians and Other Small Group Providers?

Based on the demonstration program, numerous providers and others have expressed concern that RACs are overly aggressive auditors.  Despite some improvements, concerns about the RAC process are likely to persist.  As recent testimony by the GAO Health Care Director pointed out, the oversight of RACs leaves something to be desired.

Changes have been made to reduce the RACs unintended incentive to drive up fees (through the improper denial of claims). RACs are now required to pay back their contingency fee if the claim is overturned at any level of appeal, rather than just the first level as in the demonstration program.

Additionally, there are some limitations in place regarding the RACs ability to overwhelm providers with record requests.  RACs may not request records more frequently than every 45 days and, for instutitional providers, their requests are limited to 1% of all claims submitted for the previous calendar year.  This is an overall limit, however, meaning that a RAC may determine the composition of the records in an additional document request.  They can – and do – request categories of records up to the limit even if the request is disproportionate the provider’s business.

Finally, none of these improvements address the concern that the first several levels of the appeals process do not provide meaningful recourse for the overly aggressive auditing.

Counsel for HHS-OIG Discusses the Impact of Health Care Reform on Enforcement with Congress

(June 22, 2010):  In his testimony last week before the Health and Oversight Subcommittees of the House Committee on Ways and Means, Lewis Morris, Chief Counsel to the Inspector General (OIG) of Health and Human Services (HHS), emphasized the increasing speed and intensity of HHS-OIG’s multi-pronged health care fraud enforcement efforts.  Morris’ testimony reinforces the need for Medicare providers and suppliers to aggressively prepare for a knock on the door from HHS-OIG or one of its many enforcement partners.

Morris highlighted numerous new enforcement tools available under the Patient Protection and Affordable Care Act (PPACA), paying particular attention to innovations in data access and use.  These measures include consolidating and sharing data across agencies, as well as deploying new technology that allows “investigators to complete in a matter of days analysis that used to take months with traditional investigative tools.”

He further praised the enhanced accountability measures contained in PPACA, such as HHS-OIG’s ability to impose civil monetary penalties for “failing to grant [upon reasonable request] timely access to HHS-OIG for investigations, audits, or evaluations.”  Notably, PPACA Section 6408 provides for a penalty of $15,000 for each day for failure to grant access.

Morris’ testimony also reminded the health care community that:

• PPACA allows the HHS Secretary to suspend payments to providers or suppliers based on credible evidence of fraud.  At the same time, it expands the types of conduct constituting Federal health care fraud offenses under Title 18.
• HHS-OIG has improved access to information from entities directly or indirectly involved in providing medical items or services payable by any Federal program.

Perhaps most significantly:

• Medicare and Medicaid program integrity contractors (i.e., ZPICs and PSCs) are required to provide performance statistics, “including the number and amount of overpayments recovered, number of fraud referrals, and the return on investment of such activities.” (emphasis added).

 While not surprising, it is nonetheless disconcerting that ZPICs and PSCs are essentially being “graded” based on the “amount of overpayments recovered,” along with the number of enforcement actions handled and referred to law enforcement.  Based on these performance measures, is there any real difference between ZPICs and RACs?  While RACs may be compensated directly based on the amount of overpayments collected (and ZPICs are not), it is crystal clear that the government’s expectations of ZPICs are quite similar.  Now, more than ever before, it is essential that providers implement effective compliance measures to cover their practices and clinics.

More “Bounty Hunters” Conducting Medicare Audits?

More Medicare Audits on the Way?

Yesterday, the White House announced that President Obama  intends to back additional bipartisan plans to stamp out waste in government-run medical programs for the elderly and needy.  The White House said this new effort to root out improper payments in the Medicare and Medicaid programs could double taxpayer savings over the next three years to at least $2 billion.

“We cannot afford nor should we tolerate this waste of taxpayer dollars,” the White House said.   The government believes that approximately $54 billion was lost through improper Medicare and Medicaid payments in 2009. Medicare is the government-run program covering elderly Americans and Medicaid is for the country’s poorest.

President Obama is seeking to crack down on waste and fraud as his administration strives to secure an overhaul of the $2.5 trillion healthcare system to contain costs and expand coverage to tens of millions of more Americans.  The action endorses Republican-backed proposals on alleged health care wrongdoers.

How Does the New Proposal Work?

Similar to the current RAC reimbursement scheme, the proposed new plan will offer private Medicare audit companies a share of the money that they recoup in order to encourage them to work harder to uncover improper payments under Medicare and Medicaid.   President Obama is also expected to back bipartisan legislation to expand the ability of government agencies to undertake these so-called payment recapture audits by providing more funds.  No additional information on how this will impact CMS was given.

What Steps Can Providers Take When Faced with Medicare audits?

As many health care providers will readily attest, over the past year, it appears that there has been a marked increase in PSC and ZPIC Medicareaudits, almost all of which are accompanied by demands for extrapolated damages.  Once again, this points to the importance of self-assessment and an effective compliance strategy.

This new Medicare audit risk will increase the likelihood that providers who have not been subjected to RAC or other Medicare audits in the past may now find themselves being examined by RAC-like auditors in the future.  Coupled with existing PSC and ZPIC Medicare audits, sole practitioners, small practice groups and clinics will find their coding and billing practices under the spotlight.  Unfortunately, based on recent cases we have handled, it appears that PSCs and ZPICs are increasingly imposing their own views regarding what is required, well beyond the four corners of CMS-authorized provisions set out under LCDs and LMRPs covering the services at issue.  Fortunately, when faced with the facts, ALJs have applied a reasonable approach and most of the claims at issue have been found to be payable.  We recommend that health care providers carefully review their documentation practices to lessen the likelihood that ZPICs, PSCs, RACs and these new third-party reviewers can successfully argue that the claims don’t qualify for coverage during a Medicare audit.

Are ZPICs Tougher than RACs When Conducting Medicare Audits?

Medicare Audits: RACs vs. ZPICs

The Recovery Audit Contractor (RAC) program is an integral part of the Centers for Medicare & Medicaid Services’ (CMS’) “benefit integrity” efforts which seek to identify and recoup alleged overpayments paid to Medicare providers. While the RAC program is still being expanded in many parts of the country (to cover not only hospitals but also other providers and types of Medicare claims), health care providers should be aware that the Zone Program Integrity Contractors (ZPICs) are already active in many areas and are actively conducting Medicare audits of physicians, home health agencies, hospices, DME companies, therapy clinics, chiropractors and other small to mid-sized health care providers.  Despite the “hype” surrounding RACs, at this time, ZPICs represent a significantly greater risk to non-hospital providers than do RACs.  The purpose of this article to examine a number of the differences between these Medicare audit contractor programs.

What are the chances of your practice being reported by a ZPIC or RAC to HHS-OIG or DOJ for possible fraud violations?

While both Medicare audit contractor programs are designed to “find and prevent waste, fraud and abuse in Medicare,” the fact is that to date, ZPICs have been much more likely than RACs to report possible incidents of “fraud” that are identified while conducting Medicare audits.  Frankly, it makes sense.  RACs make money by identifying alleged overpayments – not by making a fraud referral to law enforcement.  Notably, as a result of recent criticism by HHS-OIG, CMS will be requiring RACs to be much more diligent in the future about making referrals to law enforcement when it appears that a health care provider’s conduct represents fraud rather than a mere overpayment.  CMS has provided training to RACs on how to identify fraud in the near future.  Importantly, a RAC denial of claims which results in a provider repayment will not necessarily prevent HHS-OIG from investigating and making a referral to DOJ for possible prosecution, as appropriate, if there are allegations of fraud or abuse arising out of the alleged overpayment.

Notably, recent letters by ZPICs conducting Medicare audits in South Texas and in other parts of the country have been seeking copies of business related records (copies of contracts, agreements with Medical Directors, lease agreements and more), along with its request for claims-related medical documentation.  Importantly, the contractor is assessing the provider’s business relationships to help verify that referral and other business relationships do not violate the Federal Anti-Kickback Statute or Stark Law.  To reduce the possiblity of civil or criminal liability, it is essential that Medicare providers take affirmative steps to better ensure that their practices are compliant with applicable statutory and regulatory requirements.  2011 will be the “Year of Compliance.”  All providers, regardless of size, should take steps to implement an effective Compliance Program.  Should you not have an compliance program in place, give us a call — we can help.

What is different about ZPICs and their predecessors, Program Safeguard Contractors (PSCs)?

Both ZPICs and Program Safeguard Contractors (PSCs) readily point out that they are not “bounty hunters” in the Medicare audit process.   ZPICs are not paid contingency fees like RACs and are paid directly by CMS on a contractual basis.  Nevertheless, common sense tells us that if ZPICs aren’t successful at identifying alleged overpayments through Medicare audits, the chances of a particular contractor getting their contract with CMS renewed are pretty slim.  Experience has shown that both ZPICs and PSCs don’t always appear to strictly adhere to medical review standards established by Medicare Administrative Contractors (MACs) and approved by CMS.  In our opinion, there appear to have been cases where these contractors applied their own unwritten standards, often denying claims based on conjecture and speculation rather than a strict application of the applicable LCD or LMRP.

In any event, over the last year, both ZPICs and PSCs have increasingly placed health care providers on pre-payment review, conducting post-payment Medicare audits, and  recommending suspensions of payment.  Additionally, in many cases they have been extrapolating the alleged damages based on a sample of claims reviewed. Finally, as discussed above, identified instances of potential fraud are being referred by ZPICs and PSCs to HHS-OIG for possible investigation, referral for prosecution and / or administrative sanction.

What sources of coding / billing data are used by ZPICs during Medicare audits?

ZPICS are required to use a variety of techniques, both proactive and reactive, to address any potentially fraudulent practices.  Proactive techniques will include the ZPIC IT Systems that will combine claims data (fiscal intermediary, regional home health intermediary, carrier, and durable medical equipment regional carrier data) and other source of information to create a platform for conducting complex data analyses. By combining data from various sources, ZPICs have been able to assemble a fairly comprehensive picture of a beneficiary’s claim history regardless of where the claim was processed. The primary source of this data is reportedly CMS’ National Claims History (NCH) database.

How do ZPICs conduct medical reviews?

During their Medicare audits, ZPICs conduct medical reviews of charts to determine, among other things, whether the service submitted was actually provided, and whether the service was medically reasonably and necessary.  Based upon their findings, ZPICs may approve, downcode or deny a claim.  To date, we have never seen a ZPIC conclude that a claim should have been coded at a higher level, only a lower level.  Regrettably, ZPICs are not required to have a physician review a claim in order to deny coverage.  In most of the cases on which we have worked, the contractor’s medical reviewer has been a Registered Nurse.   While some Federal courts have found that a treating physician’s opinion should be given paramount weight, others have ruled that the opinion of a treating physician should not be given any special consideration.  Generally, ZPICs have completely disregarded the “Treating Physician Rule,” despite the fact that a patient’s treating physician was the only provider to have actually seen and assessed the patient at issue.

How should you respond to a ZPIC Medicare audit?

In responding to a ZPIC audit, it is important to remember that although they may not technically be “bounty hunters,” in our opinion, they are in the business of finding fault.   Moreover, they are quite adept at identifying “technical” errors, many of which they will readily cite when denying your Medicare claims.  Unfortunately, it is not at all uncommon for a ZPIC to find that 75% — 100 % of the sample of claims reviewed did not qualify for coverage and payment by Medicare.  After extrapolating the damages to the universe of claims at issue, health care providers often find that they are facing alleged overpayments of between $150,000 and several million dollars.  In many cases, the assessment is far in excess of the provider’s ability to pay.  As such, the administrative appeal becomes a “bet the farm” matter for the health care provider.  If the assessment remains, the provider will have no choice but to declare bankruptcy.

It is also important to remember that ZPIC enforcement actions are not limited to merely overpayment assessments.  In recent months, ZPICs have been increasingly conducting unexpected site visits of health care provider’s offices and facilities, often requesting immediate access to a limited number of claims and the medical records supporing the services billed to Medicare.  Typically, they then require that a provider send supporting documention covering a wider list of claims within 30 days of their visit.  In other cases, should a ZPIC identify serious problems when reviewing the medical records requested, they may recommend to CMS that the provider’s Medicare billing privileges be suspended.  From a practical standapoint, few providers are diversified (in terms of payor mix) to the point that they can easily do without Medicare reimbursement.  The practical effect of a Medicare suspension is therefore that the provider cannot continue in business throughout the 180-day initial period of suspension typically imposed by CMS.  Finally, in a limited number of cases, after a ZPIC or PSC has visited an office, the provider will subsequently learn that the contractor has recommended that the provider’s Medicare number be revoked.  In a fairly recent case we are aware of (not involving a client of the Firm), the contractor claimed that the provider failed to cooperate, a clear violation of the provider’s “Conditions of Participation” with Medicare.  As a result, the contractor recommended (and CMS approved) the revocation of the provider’s Medicare number.  Short of exclusion from participation in the Medicare program, this is arguably the most serious and far-reaching administrative action that can be taken against a Medicare provider.

In light of the seriousness of the situation, regardless of whether you are contacted by a RAC, a ZPIC or a PSC, you must take great care when responding to Medicare audits.  Administrative enforcement actions can be extraordinarily serious.  Therefore, is essential that you engage an experienced attorney and law firm to represent your interest.
