(September 4, 2009)
Before DUBINA, Chief Judge, CARNES, Circuit Judge, and RESTANI,* Judge.
CARNES, Circuit Judge:
More than a hundred years ago the mother of modern nursing, Florence
Nightingale, observed: “It may be a strange principle to enunciate as the very first
requirement in a Hospital that it should do the sick no harm. It is quite necessary,
nevertheless, to lay down such a principle . . . .”1 When Nightingale wrote those
words hospitals were not the sanitary sanctuaries they have become, and the harm
she meant to shield her patients from was new or worsening illness. Since then the
health care situation has become more complicated. Some hospitals are part of
profit-driven, multi-billion dollar corporations, and the harm they can do has taken
on additional forms. One such corporation is Tenet Health Care, and this case is
about the economic harm it did by manipulating part of the Medicare program.
I.
Boca Raton Community Hospital, Inc. is the largest hospital in southern
Palm Beach County, Florida. Tenet Health Care Corporation is the second-largest
for-profit hospital chain in the country, with more than seventy-five acute care

facilities in thirteen states including Florida. Both Boca and Tenet participate in
Medicare, a government health insurance system for the aged and disabled that is
administered by the Center for Medicare and Medicaid Services (the Center).
Medicare reimburses participating hospitals for treatments given to
qualified patients during acute care inpatient hospital stays. Instead of paying
whatever the treatment actually costs, however, Medicare pays the hospital a fixed
amount based on the patient’s diagnosis. Medicare recognized that some
treatments would cost significantly more than the standard fixed rate, so it created
an “outlier program” to supplement the fixed-rate payment in those cases. Under
the outlier program, a hospital receives additional reimbursements when the cost it
incurs to treat a patient is greater than the standard fixed-rate payment by a
specified amount called the fixed loss threshold. The loss threshold acts like an
insurance deductible because the hospital is responsible for that portion of the
treatment’s excessive cost and then Medicare disburses an outlier payment for the
amount exceeding the loss threshold.
The Center sets the loss threshold annually using a method that estimates
the level that will keep total outlier payments between five and six percent of total
inpatient Medicare reimbursements. The Center can consider a variety of factors
when setting the loss threshold, including policy concerns, public comment, and
3
expectations about inflation and the rate of change for hospital spending and
charges. Because the Center does not disclose which of those factors it uses or
how it uses them in any given year, we do not know the exact formula that
produces the loss threshold. Boca describes the loss-threshold-setting process as
an “iterative” one in which the Center begins with a “best guess” about what loss
threshold will meet its target percentage.2 According to Boca, after estimating the
next year’s number of outlier claims based on historical data, the Center then uses
trial and error until its best guess actually predicts total outlier payments equal to
the target.
The outlier program is designed to reimburse hospitals for extraordinary
costs, but during the years involved in this appeal the Center calculated outlier
payments using a hospital’s charges. To approximate a hospital’s costs, the Center
multiplied the hospital’s charges by its “audited” cost-to-charge ratio, a
hospital-specific number the Center reaches by reviewing a hospital’s most recent
settled cost reports.3 Because it takes between two and five years to audit cost
reports, the audited ratios the Center used to calculate outlier payments were
2
The total outlier payment target for 2000 through 2004 was 5.1 percent. The Center
actually paid out between 6.1 and 7.6 percent during those years.
3
The equation used by the Center to approximate costs when determining outlier
payments can be represented this way: APPROXIMATE COSTS = CHARGES × RATIO .

outdated and did not necessarily reflect a hospital’s actual current charges or costs.
Although a more current, “unaudited” ratio could be determined using a hospital’s
more recent (though tentative) cost reports, the Center used the time-lagged,
audited ratios. So an increase in billed charges without a corresponding increase
in costs made costs appear to have gone up even when they had not. As a result,
hospitals with constant costs could receive more outlier payments simply by
increasing charges.
At the end of each fiscal year, the Center calculated a national average of all
hospitals’ audited ratios. Using the national average the Center then created a
National Threshold ratio range with its high and low points three standard
deviations above and below the average. The Center assumed any audited ratios
that fell outside this range were “unreasonable, in that [they] [we]re probably due
to faulty data reporting or entry, and should not be used to identify and pay for
cost outliers.” To correct this perceived faulty data when calculating outlier
payments, the Center substituted a statewide average ratio for any audited ratio
that fell outside the range. If a hospital’s audited ratio fell below the low National
Threshold and the average ratio was substituted, that hospital would receive higher
outlier payments than it would have if its own audited ratio had been used.
5
In August 2003 the Center changed the outlier payment system in three
ways: (1) it allowed outlier payments to be calculated using unaudited ratios to
approximate actual costs more accurately by recognizing recent charge increases;
(2) it stopped substituting average ratios for ratios below the low National
Threshold so that hospitals received outlier payments based on their “actual” ratios
no matter how low those ratios fell; and (3) it made outlier payments subject to
recapture on a case-by-case basis to ensure that the finalized outlier payments
reflected an accurate assessment of the actual costs hospitals incurred. These
changes were prospective only.
Boca believed that in the period before the 2003 changes, Tenet had been
gaming the outlier program to get more reimbursements than its extraordinary-cost
cases justified. Boca filed a class action complaint to that effect in March 2005
and amended it to include a revised class definition in June 2006. In the amended
complaint, Boca alleged that Tenet increased its outlier reimbursements by
dramatically raising its charges without reference to any actual cost increases,
making average-cost cases look like outlier cases. Boca asserted that Tenet
maximized its outlier receipts by taking advantage of both the Center’s use of
outdated audited ratios that did not reflect price increases and the Center’s
substitution of average ratios for audited ratios below the low National Threshold.
6
Boca claimed that because Tenet’s charge increases were unrelated to real cost
increases, the excessive outlier payments it received from those inflated charges
were unlawful and constituted a RICO violation under 18 U.S.C. § 1962(c), (d).
As RICO predicate acts, Boca alleged that Tenet transported or received the
“stolen or converted” outlier funds in violation of the National Stolen Property
Act, 18 U.S.C. §§ 2314, 2315.
Boca originally sought to represent a class of “all acute-care hospitals in the
United States” that would have been eligible for outlier reimbursements between
2000 and 2004, or would have received higher reimbursements, but for Tenet’s
conduct. Boca later narrowed its class definition to include only acute-care
hospitals that received at least one outlier payment between 2000 and 2004, had an
unaudited ratio above the low National Threshold, and were not owned by Tenet
or a Florida governmental entity. Boca also added a component to its liability
theory by re-defining Tenet’s wrongful conduct, which it called “turbocharging,”
as the “breaking [of] any rational or reasonable relationship between charges and
costs by driving hospital [audited ratios] below the low National Threshold.” So
for both class certification and liability, Boca used the low National Threshold to
divide potential-class-member victim hospitals (those with audited ratios above
7
the low National Threshold) from non-class-member culpable hospitals (those
with audited ratios below the low National Threshold).
In describing its injury Boca claimed that Tenet’s turbocharging, and the
excessive outlier payments Tenet received as a result of it, forced the Center to
increase the loss threshold to keep total outlier payments at the target percentage.
That increase of the loss threshold caused Boca to receive less outlier money for
its legitimate extraordinary-cost cases than it would have but for Tenet’s
turbocharging. To prove its injury and resultant money damages, Boca offered an
expert opinion. The opinion purported to show that Tenet’s overcharging had
caused the loss threshold to increase, that Boca would have received additional
outlier payments but for Tenet’s overcharging, and the amount of those additional
outlier payments. Boca’s experts created a “Tenet-adjusted” loss threshold—the
loss threshold that the Center would have set if it had not had to pay out Tenet’s
unlawful outlier claims. They arrived at that loss threshold number by replacing
the audited ratios the Center used to calculate Tenet’s outlier payments with
unaudited ratios that allowed for a closer approximation of Tenet’s costs. The
experts then compared the amount of outlier payments Boca would have received
using their Tenet-adjusted loss threshold with the payments Boca actually did
8
receive. The difference in those amounts was, in their opinion, the injury Tenet’s
conduct had inflicted on Boca.
In December 2006 the district court denied Boca’s motion for class
certification. Eight months later in August 2007, the district court granted
summary judgment to Tenet after finding that its overcharging was not the
proximate cause of any loss in outlier payments Boca suffered. To reach that
conclusion the court considered the “motivating factors” behind the proximate
cause requirement described in Anza v. Ideal Steel Supply Corp., 547 U.S. 451,
126 S. Ct. 1991 (2006). The court found that the first Anza factor, whether the
connection between the conduct and the injury was too attenuated because other
things could have contributed to the injury, cut against Boca. The court noted that
some of Tenet’s charge increases could have been lawful and that the Center’s
exact reason for raising the loss threshold was not known. Many hospitals had
dramatically raised charges between 2000 and 2004, so Tenet’s overcharging was
not the only reason the loss threshold went up even if it did play a role.
The second and third Anza factors—whether damages would be difficult to
ascertain and whether a more direct victim could better vindicate the underlying
violation of the law—also cut against Boca. The court found that Boca’s injury
and damage opinions were flawed because they were not based on the amount of
9
Tenet’s overcharges. Because the government had filed its own suit against Tenet
based on the same overcharging “theft” that Boca alleged and had received a $900
million settlement, of which $800 million was recaptured outlier payments, the
court found that the most direct victim of Tenet’s misbehavior had already
vindicated the underlying violation of the law.
In the same August 2007 order, the district court granted Tenet’s motion to
strike Boca’s expert opinion on injury and damages. The experts’ methodology
did not fit Boca’s liability theory, according to the court, so their opinion did not
meet the requirements of Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S.
579, 113 S. Ct. 2786 (1993). The court noted that although Boca’s liability theory
rested on overcharging, the injury and damages calculations merely substituted
unaudited ratios for the audited ratios that the Center had used to determine
Tenet’s outlier payments. The experts made no attempt to figure out what Tenet
could have lawfully charged, so they did not know how much Tenet had
overcharged. As a result, the experts could not tell how Tenet’s overcharging had
impacted the loss threshold. Because outlier payments were based on charges
rather than costs, the court found that the experts’ decision to manipulate costs
instead of charges made their method unhelpful and thus inadmissible.

Boca appeals the district court’s denial of class certification, grant of
summary judgment, and exclusion of its expert opinion.
II.
We turn first to the district court’s exclusion of Boca’s expert opinion on
injury and damages. We review a district court’s exclusion of expert testimony
only for abuse of discretion, Gen. Elec. Co. v. Joiner, 522 U.S. 136, 141-43, 118 S.
Ct. 512, 517 (1997), which “requires that we defer to the district court’s ruling
unless it is manifestly erroneous.” Rink v. Cheminova, Inc., 400 F.3d 1286, 1291
(11th Cir. 2005) (internal quotation marks omitted). Because evaluating the
reliability of expert testimony is uniquely entrusted to the district court under
Daubert, we give the court “considerable leeway” in the execution of that duty.
Kumho Tire Co. v. Carmichael, 526 U.S. 137, 152, 119 S. Ct. 1167, 1176 (1999);
see also McCorvey v. Baxter Healthcare Corp., 298 F.3d 1253, 1256 (11th Cir.
2002).
The party offering the expert testimony has the burden of demonstrating that
the testimony is “relevant to the task at hand” and “logically advances a material
aspect” of its case. See Daubert, 509 U.S. at 597, 113 S. Ct. at 2799; Allison v.
McGhan Med. Corp., 184 F.3d 1300, 1312 (11th Cir. 1999) (internal quotation
marks omitted). The “basic standard of relevance . . . is a liberal one,” Daubert,
11
509 U.S. at 587, 113 S. Ct. at 2794, but if an expert opinion does not have a “valid
scientific connection to the pertinent inquiry” it should be excluded because there
is no “fit.” See id. at 591–92, 113 S. Ct. at 2796; McDowell v. Brown, 392 F.3d
1283, 1299 (11th Cir. 2004). The offering party must show that the opinion meets
the Daubert criteria, including reliable methodology and helpfulness to the
factfinder in understanding the evidence or determining a fact, by a preponderance
of the evidence. See Rink, 400 F.3d at 1292.
The district court found Boca’s method inadequate and speculative because
it did not attempt to show what amount of Tenet’s charges were unlawful. Instead
it focused on approximating Tenet’s actual costs more closely. To do this, Boca’s
method swapped the outdated audited ratios (or the artificially high average ratios)
the Center used to determine Tenet’s outlier payments for the more current and
accurate unaudited ratios. The court recognized that Boca’s method mirrored the
changes the Center implemented in its 2003 regulation amendments, which were
meant to close one of the loopholes opportunistic hospitals (like Tenet) had been
using to game the outlier program. But the court also noted that because Boca’s
liability theory was based on the idea that Tenet’s unlawful overcharges caused the
Center to raise the loss threshold, Boca’s injury and damages had to flow from
whatever effect those unlawful overcharges actually had on the loss threshold.
12
Without knowing the amount of unlawful overcharges, the court concluded,
Boca’s experts could never know the effect, if any, those charges had on the loss
threshold. And without knowing that effect, the experts could not show that Boca
had suffered an injury, much less the extent of it.
Boca contends that the district court misunderstood the outlier program in
general and its expert opinions’ methodology in particular. It argues that, whether
charges are reasonable or unreasonable, the Center’s cost-approximation equation
will generate the same number as long as the ratio used is accurate. Because the
Center pays outliers based on costs and not on charges, Boca argues, there is no
need to determine the amount of Tenet’s overcharging to see how it affected the
loss threshold. By replacing the “manipulated” audited ratios Tenet used to obtain
“fraudulent outliers” with “accurate” unaudited ratios, Boca asserts that its expert
opinion “isolates and removes Tenet’s excess outliers, provides a reasonable
measure of Tenet’s appropriate outliers based on its actual costs, and in turn
establishes the basis for determining the effect of Tenet’s scheme” on the loss
threshold. Tenet maintains that Boca’s expert opinion does not fit its liability
theory and would therefore “confuse and mislead the jury by impermissibly
purporting to measure Tenet’s impact” on the loss threshold.
13
The district court’s conclusion that Boca’s expert opinion on injury and
damages did not fit its liability theory was not manifestly erroneous because, like
an oversized coat, the expert opinion covered too much. Under Boca’s liability
theory, it is not unlawful for hospitals to overcharge (that is, to increase charges
out of step with costs) as long as their audited ratios do not fall below the low
National Threshold. Because Boca’s expert opinion uses unaudited ratios to
approximate Tenet’s actual costs, it includes the outlier payments Tenet got from
lawful overcharging, as well as unlawful overcharging, as part of Boca’s injury
and damages. In that way Boca’s expert opinion holds Tenet to a stricter standard
for injury and damages than its liability theory does for culpability by including
charges that were excessive but not so much so that they forced a hospital’s
audited ratio below the low National Threshold. In other words, Tenet could have
overcharged somewhat less than it did without being culpable under Boca’s
liability theory, but Boca’s injury and damages theory would still hold Tenet
accountable for even those portions of its overcharging that were not unlawful
according to the liability theory.
Boca drew a line between lawful and unlawful behavior for liability
purposes: the low National Threshold. Boca could have walked that line in a way
that fit its theory of injury and damages to its liability theory; it could have chosen
14
a method that showed that the behavior Boca claims caused its injuries, Tenet’s
unlawful overcharging, actually impacted the loss threshold. All that Boca’s
expert opinion purported to show, however, was the amount of most clearly lawful
outlier payments Tenet could have gotten—the amount of outlier money Tenet
would have received if it had used its actual costs to apply for the payments. What
Boca’s expert opinion fails to recognize (which, by contrast, its liability theory
does) is the range of behavior between clearly unlawful and perfectly lawful.
Having tailored a trim-fitting liability theory for the body of its case against
Tenet, Boca cannot hang a baggy injury and damages theory on it. Whatever
expert opinion Boca provided had to be suitably proportioned. And because
Boca’s injury and damages opinion was not confined to charges that its liability
theory would consider unlawful, it was too broad. It was ill-fitting. Thus the
district court did not abuse its discretion by excluding Boca’s expert opinion on
injury and damages for lack of fit with its liability theory.
III.
Our conclusion that the district court did not abuse its discretion in
excluding Boca’s expert opinion on injury and damages compels a second one:
that the district court’s grant of summary judgment in favor of Tenet was
appropriate. Without its expert opinion, Boca has not offered any evidence of
15
injury—an essential element of its RICO claim. See 18 U.S.C. §§ 1962(c),
1964(c) (authorizing “[a]ny person injured in his business or property” by an
unlawful pattern of racketeering to “recover threefold the damages he sustains”);
McCaleb v. A.O. Smith Corp., 200 F.3d 747, 752 (11th Cir. 2000) (“There is no
liability if a RICO violator has not caused injury.”); Beck v. Prupis, 162 F.3d
1090, 1095 (11th Cir. 1998) (“[A] civil RICO plaintiff must show that the
racketeering activity caused him to suffer an injury.”). Thus we do not need to
address the second reason the district court gave for granting summary judgment,
that Tenet was not the proximate cause of Boca’s injury.4
The district court made a point to emphasize, as we do now, that while
summary judgment for Tenet was appropriate, Tenet was not blameless. The
record shows that Tenet hospitals took advantage of a system designed to help pay
for the sickest and least fortunate patients to heal. The people hurt the most by
Tenet’s manipulation of the Medicare outlier program through excessive charge
increases are the uninsured, who are forced to pay hospitals’ “sticker prices”
instead of the reduced rates insurance companies negotiate for their clients. This
4
Because summary judgment was appropriate, Boca’s challenge to the district court’s
denial of class certification is moot. See Rink, 400 F.3d at 1297 (“Because we have found that
summary judgment was properly granted as to the underlying claims of the class representatives,
the issue of class certification is moot.”).
16
may not be what Florence Nightingale had in mind when she warned about the
harm hospitals could do, but it is still a harm against which patients deserve
protection. The government has addressed this new strain of harm by recovering
almost a billion dollars from Tenet and making changes to the way the outlier
program runs. Hopefully those actions will help prevent similar abuse in the
future and serve to remind hospitals that their first duty is to do no harm to
anyone.
AFFIRMED.
