IN ADDITION TO THE USUAL WITCHES’
brew of hard fraud, soft fraud, staged accidents and
slip-and-fall fraud rings, insurance carriers must contend with increasing instances of fraud borne of a policyholder’s adverse financial circumstances. The home-owner or SUV owner seeking to get out from under a
loan with a little help from a can of kerosene is far from
apocryphal. “Fraud has historically been committed
out of acts of greed,” says David Rioux, VP of corporate
security and the special investigative unit (SIU) for
Erie, Pa.-based Erie Insurance. “Now, given the economic situation we’re in, fraud is being committed out
of acts of desperation.”
Perhaps as troubling as the fraudulent claims carriers
manage to detect, are the frauds that escape detection.
“The funny thing about fraud is that nobody knows
how much there really is,” notes Donald Light, a senior
analyst at Boston-based Celent. “Insurers only know
how much they have found—they don’t know how
much they haven’t found.”
When it comes to fraud detection, experience is often
the best teacher. “Insurers are always getting better at it,
but, by nature, you almost have to be burned before you
find the fire,” adds Robin Harbage, C-counsel consultant
at San Diego-based EMB in North America.
While the totality of insurance fraud is likely
unknowable, new data from the Des Plaines, Ill.-based
National Insurance Crime Bureau (NICB) offers one
way of quantifying the problem. NICB data encompass-es property/casualty, commercial and vehicle data, but
the most pronounced surge occurred in auto claims, as
suspicious car fires were up 20% from last year, suspicious auto glass claims up 76% and “phantom” accidents were up 46%.
In fact, for the first half of 2009, NICB data shows
increases in nearly all referral categories compared with
the first half of 2008. Overall, a total of 41,619 questionable claims were referred to NICB for closer review
and investigation by member insurance companies in
the first half of 2009, compared with 36,743 received
during the same period a year earlier.
This upswing in fraud is not limited to the property/casualty sector. Workers’ compensation claims can
swell as workers anxious about layoffs file claims, aware
that workers’ compensation benefits are generally larger and longer-lasting than unemployment benefits.
So how do insurers stem this tide? By making better
use of their most abundant and critical asset: data. Using
predictive analytics to fight claims fraud is not new.
Once the province of the well-heeled, the proliferation
of predictive analytics technologies means now most
any insurer has the financial and technical ability to
bring these solutions right to their desktops. While the
solutions have improved significantly in the past five to
10 years, sporting better graphic interfaces and greater
use of visual link analysis to aid in the identification of
suspicious claims, they are beginning to plateau. “From
a pure technology perspective, there is not much new
in the last few years,” acknowledges Light.
THE HUMAN FACTOR
Absent technological leaps forward, how are insurers
advancing the use of predictive analytics to fight fraud?
One strategy is to use predictive analytics to augment
human decision-making, or make better use of human
capital. As analytic models shift from batch mode to
real-time, they can help with areas such as adjuster
assignments. For example, an experienced adjuster
could be assigned to an accident scene while remnants
of the accident are still present.
“I look at predictive analytics as a data watchdog—a
guide for adjusters and investigators to be on the alert
to critical data,” says Gregory Melanson, manager, special investigation unit, for Warwick, R.I.-based MetLife
Auto & Home. “You have finite resources, so you only
want to investigate files that really need it.”
Melanson says it is important to synthesize information culled from analytics with human interpretation.
Insurers can integrate predictive analytics with existing
business rules, such as special consideration for any
claims that occur within the first two weeks of a new
policy. “You are not going to pay three years’ worth of
premiums and then make a claim,” Harbage says.
“Many fraudsters will make a claim before the check
clears or bounces.”
While Melanson says the insurance industry is not
trailing fraudsters, he sees areas where insurers can be
more proactive. For example, incorporating existing
technologies such as geo-coding can help investigators
ferret out fraud, he says. “It may prompt an investigator
to ask: Why would someone go to a medical clinic 50
miles away?”
Yet, just because a model flags a claim it doesn’t necessarily mean the claim is fraudulent. Analytics can
highlight exonerating behavior in a seemingly suspicious claim as well, saving the adjuster the time and
aggravation of following a false lead. Analytics works
best when paired with solid claims management and
diligent investigative techniques. Melanson stresses that
the technology is not an exact science, and companies
need to guard against becoming over-reliant on analytics. “Often there are mitigating factors that are not in the
data,” he says.
Likewise, Rioux says predictive analytics work best as
a conduit to the information needed by adjusters and
investigators to make informed decisions. “From the
first notice of loss throughout the entire life of the
claim, we continuously score the claim, and there is a
threshold we set,” he says. “When it breaks that threshold, a notice will go to that claim handler.”
Rioux says analytic models now account for one-third
of referrals to SIU. “That’s actually a very good number,”
he says. “The reality is there are some adjusters that don’t
benefit as much from predictive analytics; they find these
things off gut feeling.”
One area where Rioux concedes humans come up
short is in consistency. Automation breeds consistency,
he says. While adjusters and investigators can suffer
from workload or training issues, predictive models do
not. “It levels the playing field across an organization,”
he says. “One thing about technology is that it doesn’t
have good days or bad days. Our claims are being scored
consistently across the organization.”
THE NOTES
Oddly, one bountiful source of predictive information—the copious amount of notes created by
adjusters—has only recently been incorporated in predictive models. Traditionally, carriers would use structured data such as historical records of known claims
fraud, plus policy and public data to build their predictive models. Presently, steady advances in text mining
capabilities have made this once-underutilized asset
another primary feedstock for analytics. Rioux says Erie
now incorporates adjuster notes into its predictive
models, which were originally built using hundreds of
predefined data fields such as names and addresses.
“One of the more recent additions to our solution
was the introduction of adjuster loss notes because text
mining is huge,” says Rioux, who is also president of
International Association of Special Investigators,
Baltimore. “The notes tell the story. Data fields just hold
pieces of information. Being able to read notes, and
organize them in a fashion useful for the model, has
really given predictive analytics a substantial lift.”
