Denials for Lack of Physician Orders

Connolly Review Results Letters Arrive Soon After Records Submitted

Word to the wise: Make SURE you have a process in place to check ALL (Medicare, at least) claims that go out your door to be paid, to insure that a clearly worded, appropriate Physician Order exists in the medical record.

If you do NOT insure that the order exists, you are risking the entire reimbursement. And if CMS decides that a pattern of this type of error is in your facility or practice… you are risking FAR more than that reimbursement.

Before I get to the subject of the headline, let me review what else was going on, recently.

Seven New Issues Posted

Last week was a pretty quiet week, which almost no activity by any of the RACs, except for a few additions by Connolly and HDI, on Friday, September 17. Connolly added 20 new DRG Validations, listed in five of six new (yes, really NEW) issues.

1 Duplicate Claims – DMEPOS
2 MSDRG 056: Degenerative Nervous System Disorders with MCC
3 MSDRG 057: Degenerative Nervous System Disorders without MCC
4 MSDRG 249: Percutaneous Cardiovascular Procedure with Non Drug-Eluting Stent without MCC
5 MSDRG 368, 369, 370, 371, 373, 377, 378, 379, 380, 381, 382, 383, 384, 385, 387, 388, 389, 390, 391, 392, 393, 395: Gastrointestinal Disorders
6 MSDRG 820: Lymphoma and Leukemia with Major O.R. Procedure with MCC

HDI added Part A Services delivered during a Hospice period.

1 Hospice Related Services – A

But these “new” issues are not all that happened…

Many Edits Made

Over the past couple of weeks, there have been many edits made to existing posts on all four of the RAC sites.

For example, many posted issues for Region A, DCS, actually removed some states from some of their approved issues. You might want to check the list, especially if you are in Vermont, New Hampshire or Maine. (Vermont was dropped from 14 issues, New Hampshire from 12, and Maine from less than that.)

Acute readmissions have been a recognized target for RACs for some time. There was an interesting edit made to the issue as posted on Region D, HDI’s site. Previously, the issue would deny for same day acute re-admissions for the same DRG with no B4 codes on the second claim. Now, it denies for no B4 or 42 Condition Codes on the second claim.

Another edit made in Region D: under the DRG Validation issue for Nervous System Disorders, MSDRGs 075 and 076 were specifically removed from the approved DRG list. Now, I caution everyone, be careful to not transpose those numbers – in the same issue are the approvals for Medical Necessity and DRG Validation for MSDRGs 057 and 056. I warn you because I myself have more than once looked at the list and been puzzled by it, when I kept thinking that the wrong ones were removed.

Denials for Lack of Physician Order

Despite the lack of activity on the lists themselves, the RACs have been very busy, sending out review results letters and denials. We have seen in Region C the first denials to come thru for a lack of or improper physician orders in a medical record. The types of claims being denied are both inpatient and outpatient. I can give you two examples that happen to be short stays.

An outpatient claim, where the patient wound up staying for 3 days. At some point, the patient’s status was changed to inpatient, which would have been appropriate (I’m told by the provider), except for one thing: in the documentation, there is a Nurse’s note, changing the patient status to inpatient, but there is nothing at all in the record that indicates that a physician ever approved or ordered this change. The claim was therefore denied, and the provider has no chance on appeal, because the physician’s order simply does not exist.

An inpatient claim, a 1-day stay: the patient was admitted to inpatient, even with just an 8-hour stay. I was told that the services were, in fact, inpatient services, and could have survived audit for inpatient status. Well, it could have survived, except for one thing: no physician order appears in the record to admit to patient to anything. Once again, the claim was denied; and again, there is no chance to appeal, since the order simply does not exist in the record.

Want to know the scary thing? Those claims were very easy to deny, they are not “worthy” of appeal, and the provider told me that the number of records requested was very few, compared to the limits that the RAC could ask for. In other words, the RAC knew exactly which records to ask for, and they were right on the money.  It seems like this is the proverbial “Easy Money” for the RAC.

Like I said, “Word…”

Why Did They Wait?

But if this is so easy, then why wasn’t the RAC doing this more, before now? My opinion is that the RACs have been waiting for at least some of the Medical Necessity issues to be released, so that they don’t have to ask for the records again, or so that they can have all their weapons loaded before they begin the battle in earnest. I think it is because the RACs are private companies, who actually care about efficiency. In the private sector, efficiency means more profits, and this makes private sector companies much better at this kind of work than many government agencies, who don’t have to worry about such “bourgeois” concerns as “profits.”

So What’s the “Word”?

Providers need to insure they have a reliable process in place to check documentation for physician orders before any claim is filed.

Which ones should they check? Only the ones they intend to send out the door. The RACs are willing to do this job for just nine percent of the claim (in Connolly’s case, anyway).

A provider, then, should be willing to do this for slightly more than that… say, 100 percent of the claim.

So I guess I’ll say that’s the “Word”: 100%.

That’s what is at stake, and that’s what providers should check.

RAC 101 – The Movie

New Video Posted by CMS

CMS posted a recording of a RAC 101 seminar conducted by Connie Leonard and Commander Marie Casey, earlier in April. If you missed the RAC 101 conference call on April 28, this is probably the same script.

The video includes a short Q&A period, with what we would characterize as typical FAQs.

However, there were two questions asked during this video that produced two previously unheard answers:

  • While RACs can use extrapolation, there are currently no issues approved that can use extrapolation; and
  • When one RAC is approved for a new issue, the other three RACs do not automatically receive approval for that same issue — the other RACs must submit their own case to be approved for their region.

Part A Denial is NOT Automatic Denial for Part B Services, Says Medicare Appeals Council

The Centers for Medicare and Medicaid Services (CMS) recently asked the Medicare Appeals Council (Council) to review and overturn an Administrative Law Judge (ALJ) “partly favorable” decision for O’Connor Hospital, of San Jose, California. The case originated in 2007 during the Recovery Audit Contractor (RAC) Demonstration Project. In its request to have Council review the appeal, CMS attempted to argue that the Part B services were not separately billable under Part A, and therefore the ALJ had erred as a matter of law when it ordered CMS to pay the provider the difference between the covered and non-covered services.

On February 1, 2010, the Council posted their decision: they did not agree and stated that the position of CMS was essentially inconsistent with policies found in its own manuals.

On December 7, 2007, the RAC charged with auditing California providers denied Medicare coverage for a claim of inpatient hospitalization services, as furnished to a beneficiary on November 1, and 2, 2004, at O’Connor Hospital. The RAC found the services provided were not “reasonable and necessary” per the Social Security Act, and therefore the hospital had received an overpayment. Like virtually every other claim filed by a RAC during the demonstration, said overpayment finding was upheld at both of the first two levels of the appeals process.

The first level of appeal in the RAC program, when requested by the provider, is a Redetermination. This is an additional examination of the claim by the RAC, supposedly by personnel who are different from the personnel who made the initial determination. One might consider this as simply a chance to ask the RAC to be sure to check their paperwork. We are not aware of any denials being overturned at this level of appeal during the Demonstration project.

The second level of appeal, again when requested, is a Reconsideration. These are always conducted by a Qualified Independent Contractor (QIC), thereby allowing an independent review of medical necessity issues by a panel of physicians or other health care professionals. (This is a change from previous programs, but did not originate with the RAC. These reviews were instituted in Section 521 of the Medicare, Medicaid, and SCHIP Benefits Improvement and Protection Act of 2000 (BIPA), and replaced the Hearing Officer Hearing process for Medicare Part B claims, while creating a “new” second level of appeal for Medicare Part A claims.)

The provider took the claims to the next level of appeal, the Administrative Law Judge, or ALJ. There were four claims in question for four different beneficiaries at O’Connor. On September 16, 2009, the ALJ overturned the RAC denial for three of the four claims, thereby reversing the denial and granting Medicare coverage for the inpatient services, as filed. The fourth claim, however, was a more sticky situation.

While the ALJ agreed with the RAC and denied the coverage for the inpatient services provided as billed on the fourth claim, the ALJ nevertheless found that “the observation and underlying care are warranted.” In other words, yes, the inpatient admission was not warranted, but the observation and other outpatient services were warranted and should therefore be paid by CMS, even though the services were never billed as such. Or, put another way: “down-code” the claim to Part B services and pay those.

The net effect was to reduce the recoupment to simply the difference between the Part A and Part B services provided for the fourth claim only, compared to complete recoupment of all four inpatient claims, as the RAC originally decided.

Even without knowing the exact figures involved, this all suggests that CMS may have lost money on the entire process — they had to return all monies recouped, less the difference noted, but the RAC got to keep their entire commission/fee/bounty, per their contract with CMS.

Of course, while the provider got back almost all their reimbursements for the four claims, they still had to pay legal fees out of their own pocket. Considering the time involved, these were likely not insignificant.

Without reviewing all the documents here, we do wish to note a few things we think providers should consider about these decisions, regarding potential strategies for RAC appeals:

First: Bring these decisions to the attention of your legal counsel. Providers should bring both these  decisions to the attention of their legal counsel, and their RAC Team.

Second:  In Part A Medical Necessity Denials, fight for reimbursements for Part B services, if provided. Medical necessity reviews have not yet been approved for RACs, but they are likely to begin at any time. Although the O’Connor case was a result of a RAC Demonstration project denial, the Medicare Appeals Council decision is at least the second time that the Council has reminded CMS that they in fact have current policies in place that not only say that such claims should be paid as described in these cases (unbilled Part B services are sometimes payable when Part A is denied), but that CMS even instructs contractors to do exactly that. These cases offer good reason to believe the Council will render decisions in the future that are consistent with these two.

Third: In such cases, refile for Part B services as provided. The date for “refiling” a claim under such circumstances could be difficult to determine, but may depend upon what the Medicare Appeals Council considers as “new evidence” — which, at least in the case of the UMDNJ appeal, could be inferred from the fact that the contractor reached a denial decision and informed the provider of same, thereby supplying the provider with “new evidence.” Even without such a date for “reopening” the file, in the case of the O’Connor appeal, the Council found that the time limit is simply the end of the entire process, its “finality.”

Fourth: Familiarize yourself with these decisions. The Council cites several documents that are important to the decisions.

The documents cited can all be found HERE on www.myedutrax.com in our Documents Section.

CMS Expands RAC Records Requests Limits

Limits Now Apply to All Institutional Claim Types, Not Just DRG Validations

The Centers for Medicare & Medicaid Services (CMS) modified its FY2010 Additional Documentation Request (ADR) Limits, expanding the scope of the rule to include all institutional providers, on January 28, 2010. Previously, the rule applied to ADRs for DRG Validation issues only, as posted by CMS on December 1, 2009, and would have only applied to Medicare Part A providers. CMS also indicated that more changes are yet to come, with rules applying to physicians and other types of providers, including DME suppliers.

The December posting indicated that there would be two “caps” made on RAC ADRs, during FY2010. Through March 2010, the cap would remain at 200 ADRs per 45 days for all providers/suppliers. However, from April through September 2010, providers/suppliers who bill in excess of 100,000 claims to Medicare, across all claims processing contractors, would have a cap of 300 ADRs per per 45 days.

These limits would apply per “campus” instead of per NPI (National Provider Identifier). The definition of a campus is CMS’s new method of calculating limits, and is based on providers’ Tax ID Numbers plus the first three numbers of the ZIP code where those provider entities are physically located.

This most recent posting does not change any of the previous limits or definitions, but does expand the rule to apply to all claim types, not just DRG Validations.

Read the new document  HERE , along with a copy of the text from the December document.

Automatic Denials First Up

At the recent RAC summit in Washington, D.C., the RAC spokespersons stated a few things you should know about, so we repeat them here.  Also, because it is so important, we offer a list of our articles about Medical Necessity, at the bottom of this post…

Claims Data Not Yet Distributed

The RACs have evidently not yet given the RAC Contractors access to the claims data warehouse. The natural question is then, so when will they give the contractors access to the data? No date has been set, that we’ve heard of, but it would seem that it should be soon. After all, they have already begun the “provider outreach,” (see previous post) which was a stated requirement before demand letters could be sent out. So, there would appear to be no more stops to remove. Realistically, however, we would guess that demand letters probably won’t start appearing for a month or two, at least, for the first states affected.

Black & White Issues First

The RACs claim that in the interest of causing as little controversy as possible, at least to begin with, the first denials will all be for so-called “black and white” issues. That is, the RACs will begin with only automatic denials, which are not subject to appeal. Automatic denials happen by “scrubbing” the data for issues that are known to be absolute violations of the payment rules, but were somehow missed by the edits already in place in the payment system. These denials do not require the RAC to see the documentation, and therefore they do not send out any requests for copies of the records from the facilities/practices. So, the good news is, they won’t ask for you to copy any records for these denials. The bad news is, you have no right to appeal, period.

Disclosures Encouraged (by CMS)

The RACs recommend that self-disclosure of overpayments is the best course of action. That is, if you know about a problem, because you’ve found it in an internal self-audit, they say you should go ahead and tell them about it. It’s not hard to see why they would recommend this action. First, it lets CMS not have to pay the bounty-hunter fees to the contractors, and it also gives CMS additional data to use to find the same problem in other facilities. So, is it really a good idea for a facility to self-disclose? We’d advise you — maybe.

We’re not lawyers, so we can’t give legal advise. However, we would advise any facility to tread carefully and with legal counsel at your side, absolutely. Preferably, you should have counsel with experience in healthcare audits and appeals. We work with several such firms: if you need recommendations, just contact us.

Medical Necessity Is Still A Major Target

But this is no surprise, yes?  If you’ve been following this process, you already know that Medical Necessity denials made up about 40% (in reimbursement dollars) of all denials in the RAC Demonstration Project. One thing we wish to continue to point out: when the RACs mention Medical Necessity, you need to keep in mind what they can look for, in the documentation.

Reread our previous post on clinical versus contract language. The RACs do not have to show or even disagree with the clinical decision associated with a billed code — they don’t have to question whether the patient needed the procedure or care given. They could, but they don’t have to go there to get a denial. They can simply disagree with the location, the setting that the care was given in — e.g., was the care appropriate for outpatient versus inpatient? Sometimes, the answer is clear, and sometimes it’s not.

You must pay attention to the setting, AND the documentation to show that the setting was appropriate, in order to keep the reimbursement. If the RAC decides that the documentation does not support the setting (for example, that the procedure billed should have been billed as outpatient, rather than inpatient), then the RAC can recoup the entire claim, including all the ancillary procedures, codes, bills, etc., even the ones from the physicians themselves. And you can recover little, if anything, on appeal.

The only good news in this last part, is that these types of denials can only be done via the Complex Reviews, not the Automatic Reveiws. So, since the RACs will start with the Automatics, these denials will come later.

That gives you, dear reader, a month or two extra perhaps, to do more internal audits and figure out your own problems before the RACs find them.

One last thing to remind you about, and hopefully motivate you to do those internal audits…

RACs Can Use Extrapolation

It was confirmed at this conference that the RACs will be able to use the practice of Extrapolation, but without the usual constraints of having to do all the scientific proofs of how they got the data, and used statistically valid random samples. Whatever that means, we are certain that it means that the RACs will be even more motivated to find these issues, because now they will be allowed to figure out an error rate, as a percantage of your claims, and M-u-l-t-i-p-l-y.

Example: The RAC asks for 100 records from you, concerning 1-Day Stays, for DRG XXX. In that batch, they find 45 errors for lack of documentation for Medical Necessity. That means they get to recoup 100% of the claim, for each of those errors. Let’s say that just cost you $450,000. Bad, but not horrific, you think…but they’re not done. The RAC can use Extrapolation, going back 3 years (but not earlier than 10/1/07).  So, based on that, they find that you filed 450 claims like those, over that time period. Now, via the magic of Extrapolation, they get to say that 45% of all 450 were likely in error — or 202 claims, at an average reimbursement of $10,000.

Voilà!  Now they recoup $2,020,000. And that’s just one DRG. Ouch!

It gets worse: since the denial was based on Medical Necessity, you cannot win on appeal.

See our other posts on Medical Necessity:

CMS Bans Rebill For RAC Denials

Inpatient claims denied by a RAC for medical necessity cannot be resumitted. CMS has recently made this very clear, via an FAQ posted on their website:

The FAQ Question posted: “If I receive a demand letter from a RAC because a service didn’t meet Medicare’s medical necessity criteria for an inpatient level of service, can we re-bill all the services on an outpatient claim?”

Answer: “Providers can re-bill for Inpatient Part B services, also known as ancillary services, but only for the services on the list in the Benefit Policy Manual, Chapter 6, Section 10. [ find the document here, try pg 10, ff. ]

So, the bad news is that the Part A services cannot be re-billed. The good news is that some of the Part B services, MAY be able to re-billed. The answer continues…

“Rebilling for any service will only be allowed if all claim processing rules and claim timelines rules are met. There are no exceptions to the rules in the national program.”

No exceptions, period, but the you can re-bill IF and ONLY IF the timeline rules allow it. Here’s one more detail about the time limits…

“The time limit for re-billing claims is 15-27 months from the date of service.” [ find the appropriate Claims Processing Manual, Chapter 1, Section 70, here ]

The good news there is that currently, the RACs cannot review claims dated earlier than October 1, 2007. So, that is only 16 months before today (February, 2009), meaning that any claims denied under this type of review by a RAC can therefore be re-billed, at least for the ancillary services. You need not worry about the time limit running out, then, until RACs can review claims outside that limit, which will not happen until January 1, 2010.

Meanwhile, re-bill what you can!

RACs Target FFS Only

The permanent Recovery Audit Contractor program will evidently only be reviewing and targeting Fee for Service claims filed with Medicare. This is confirmed in recent documents from CMS.

CMS recently posted the transcripts for two Open Door Forum Conference Calls, conducted November 12 and 13, 2008. We have studied these calls and will be making several posts concerning what can be learned from the calls. If you wish to download these transcripts and read them yourself, use these convenient links at www.myedutrax.com :

click here for Transcript for Part A Providers

click here for Transcript for Part B Providers

Meanwhile… here’s a key statement made by a CMS representative (see pp 60, f.):

“The recovery audit contractors will be given all of the Medicare claims for their jurisdiction that were [billed] to the fee for service Medicare program. So HMO Medicare is off the table, prescription drug benefit is off the table. But every other claim type is on the table and available to the RAC for review should they choose to pursue it.”

She is then asked by a caller if all individual 1500s for physician professional claims will be available for review by the RACs. Her reply was:

“Yes, that is correct…the permanent RACs will be able to review any and all services billed by a physician or any other provider who bills the fee for service [to] Medicare.”

The good news is that HMO Medicare and all Part D claims are, at least for now, not available for review by the RACs. Of course, that could change…

The bad news is that all physician claims made on Form 1500 are already in the hands of the RACs.

RACs Affect MDs Also

So here we are, at a facility of about 500 beds, in a room with the CEO, the CFO, the Corporate Compliance Officer for the parent firm, some outside auditors, at least one lawyer, four key MDs for the facility, and the VP of Medical Affairs, all gathered to discuss the RACs — the impending attack of the RACs. Yes, our favorite subject, go figure. We give our now fairly memorized presentation about the RACs, how they began, what they did, what they are doing now, and what they’ll be doing in the near future. Probably at their doorstep, too.

What the MDs were especially astonished to find out is that THEIR incomes are going to affected, as well as the hospital’s. Not only were they unaware of how the RACs operated, but they were also unaware of how the RAC could reach into their pockets, THRU the hospital claims.

Here’s what we mean:

When a RAC disallows and takes back reimbursement for a hospital claim, any attendant professional services (i.e., the MD’s billings) can ALSO be disallowed, and taken back, especially if the claim was disallowed due to lack of documentation to support Medical Necessity.

After we finished the presentation, the VP of Medical Affairs, an MD, asked if we knew how many MDs in the country are even aware of the risk that the RACs pose to their livelihood. Our answer: we don’t have a number, but we are certain it is very small, ridiculously so. Less than ten percent? Yes, we think that is probably about right.

One of the MDs then said, “Wait a minute… so what you’re telling us is that for the first time, it is in the interest of the physician to work directly with the hospital to insure that they get reimbursed correctly?”

Yes, that’s EXACTLY what we are saying. Both MDs and hospitals need to pay attention. This is not just about coding! The hospital is dependant upon the coder to properly code a claim. The coder is totally dependant upon the MD for the documentation for that claim.

Physicians must learn at least some of the Case Management Protocols, which are now more than ever being required to ensure proper, optimized reimbursement. (Or in some cases, any reimbursement AT ALL.)

We’ll be discussing this more, in further posts. You might also wish to read some of our previous posts, such as these:

How Much Do RACs Take?

Unfortunately, this is not a simple question… We thought this needed some clarification, at this time.

We have mentioned before that the RACs take back 100% of a claim when they issue a demand letter. (See Can I Resumbit? and Principal Diagnosis for examples).  We stand by those posts, but perhaps they need some explaining. You should consider them accurate, however, given past experience. During the pilot program, the RACs demanded 100% and very rarely allowed any resubmit of a claim. In the future, however, there may be some different experiences, depending upon the prevailing winds, the attitudes of any specific RAC program contractor, and perhaps the price of tea in China, who knows.

At eduTrax we are dubious that the RACs will demand less than 100% of a contested claim, since they are authorized to do so (currently), and they are, after all, PAID based upon the dollar amounts that they recoup.  See how much they make HERE.

We do allow that there is the possibility that a RAC will only demand the difference between their interpretation of the correct payment versus what was actually paid. But we’d like to point out that there is no reason to believe that the RACs actually participate in the program out of any altruistic concerns for the state of healthcare in the USA.

The RAC contractors participate for the oldest reason there is — they are well paid to do so, and the more they recoup, the more they profit. See our post on the recent delay in the program, initiated only due to legal wrangling by two firms who lost out on their bids to become RAC contractors. See the news article about it on our Latest News page, at www.myedutrax.com.

The only good thing we can say is that, absent any fraudulent activities or intent, the MOST they will demand is 100% of the specified reimbursements.

We realize that is not very reassuring. Many of our clients have decided to reserve 100% of reimbursement for any cases they can internally identify as problematic, through our audits and use of our courses and tools. We believe this to be a wise practice. We can all hope that they can only lose the difference between the amount that should have been submitted, versus the amount that was filed and paid. But there is, at this time, no evidence to support that hope.

For the sake of argument and to explain further, the possibility exists that RACs will only demand the difference between the correct versus the incorrect reimbursement. For example, as we explained in Too Late to Query, using an incorrectly coded case for a secondary diagnosis, if a RAC demands the entire amount of the claim, then the facility is out about $9000. If however, the RAC only demands the difference between the correct & incorrect coding, the facility is only (only?) out about $3000. The problem we have with this idea/hope involves the motivation of the RAC: they are in this for profit, nothing else. Let’s call these “fees” commissions, which is more accurate…

The difference between the two potential demand letters is $9000 versus $3000, a difference of $6000. The commission for the Region A RAC is 12.5%: the choice then is $1125 versus $375. Why would the RAC choose the smaller commission?

Of course, the RAC must return any commissions paid to them for demands that are successfully appealed. We have seen that the likelihood of appeals is low (less than 15% were appealed in the demonstration project) and the likelihood of being overturned on appeal is even lower (less than 5% were overturned). (Find the CMS Report here.)

And finally, there’s this — the AHA has estiimated that it costs a provider an average of $2000 to file an appeal for a claim in the RAC process.

So, armed with that knowledge, how many claims will YOU file appeals for?

Now you know why we’ve said the RACs will take 100% of the claim, not just the difference between the right and wrong reimbursements. There’s no incentive for them to NOT take 100%.

Too Late to Query

When a RAC requests a medical record for review, it is unlikely that the RAC will accept a Query from a physician in retrospect. RACs have only on rare occasions accepted a Query Form provided by an MD long after the claim was filed. If the specificity is not there when you’re coding a claim, that’s the time to send out the Query Form. Let’s look at an example of mis-coding due to a lack of specificity in the documentation, which was… oops… not queried at the time.

A patient is documented with aspiration pneumonia (507.0) and renal disease. The pneumonia codes to 507.0 as the Principal Dx. The Secondary Dx is more problematic, since the physician needs to give more specificity to get the most accurate code. With no specifics, it should be coded as Chronic Kidney Disease, Unspecified, code 585.9. But often, we’ve seen such a case coded as 585.6, End Stage Renal Disease (ESRD). However, if the MD does not say “end stage” in the documentation, then the case MUST be coded as Unspecified.

What’s the difference? The 507.0 Pneumonia with a 585.6 End Stage Renal Disease code will group to MSDRG 177 — a typical facility would get about $9,025.00 for that. But if the secondary is 585.9, the Unspecified code, then the grouper returns MSDRG 179, which only pays about $6240. The difference, then, is almost $3000. And that’s just if you undercode.

What happens if you overcode and then the RAC does an audit? THAT will cost you the entire claim.
