A closer look at medical
expenses that drive the cost of claims
In the annual State of the Line released in May
by NCCI Holdings, Inc., the President and CEO Stephen J. Klingel notes,
“ NCCI’s short-term view of the (Workers’ Compensation)
line is optimistic, but the long-term view remains cautionary due to a series
of critical issues that continue to face the business. As always, in a cyclical,
long tail line such as Workers’ Compensation insurance, we need to
be mindful of those challenges that threaten to negatively impact our business.”
One of the major areas of concern is the continued escalation of medical
costs. In Workers’ Compensation, this is compounded by the problem
of over-utilization of medical services.
According to a recent survey of more than 70 health insurers representing
more than 100 million insured individuals prepared by Aon Consulting, the
costs of providing health care are projected to rise from 10.7% to 11.2%
in the next twelve months. Add to this the fact that in recent years, Workers’
Compensation medical claims severities have been increasing at a faster
rate than medical inflation alone and that studies have shown Workers’
Compensation pays more than group health to treat comparable injuries, it
is clear that medical cost benefits will continue to drive the costs of
claims.
An NCCI study, "Measuring the Factors Driving Medical Severity: Price,
Utilization, and the Mix", by Tanya Restrepo, Harry Shuford and Nathan
Beaven examined the factors responsible for the ongoing escalation of medical
severity in Workers’ Compensation claims. While price increases were
a minor factor, the growth in the number of treatments was the key driver.
Accounting for approximately a 35% increase in medical severities over the
years studied is the markedly higher number of treatments within each diagnosis
and a different mix of treatments across service categories. For example,
there might be a shift from diagnostic radiology to complex diagnostic testing
or complex surgery to physical therapy.
The following charts show the increase in the number of treatments by diagnosis
code for the years 2001/2002 compared with 1996/1997.

Driving Medical Severity, Price, Utilization, Mix by Tanya Restrepo, Harry
Shuford and Nathan Beaven.
The overall number of treatments increased for each of these diagnoses,
ranging from an increase of 7% for unilateral inguinal hernia to more than
80% for sprain of knee and leg. For all diagnoses combined, the number of
treatments increased 45%. Looking at the service categories, the three service
groups with above average increases in the number of treatments over the
study period were physical therapy (67%), complex surgery and anesthesia
(60%) and complex diagnostic testing (57%).
An NCCI study comparing Group Health and Workers’ Compensation in
14 states from 1996 to 2004 also revealed that Workers’ Compensation
pays more than group health to treat comparable injuries and that utilization
differences explain 80% of the overall treatment cost difference. Chronic
pain-related injuries such as bursitis, back pain and carpal tunnel have
particularly large differences.
The results of these studies suggest that the primary factor propelling
the upward trend in medical costs is changing patterns of utilization. Since
utilization is a function of the injury, this highlights the value of injury
specific cost controls aimed at over-utilization such as the application
of evidence based guidelines.
Workers’ Compensation is a complex system and many parties contribute
to medical decisions. While medical providers make initial testing, treatment
and disability management decisions, claims adjusters, employers, nurse
case managers, attorneys, and injured workers also make decisions about
care and absence from work. These groups often use standards that are not
based on evidence of effectiveness, but on a myriad of other factors, including
traditional insurance industry practices, perceptions of regulations, threats
of legal action, peer and family advice, and physician statements made without
scientific evidence.
With the seismic shifts in medical innovation and the corresponding increase
in treatment options and costs, providing appropriate, quality medical care
requires a basis in scientific evidence. If the employer provides timely
access to excellent medical care that uses objective, scientific-based guidelines
to treat job-related injuries and focuses on a return to work, the employer
and the employee benefit. Ensuring that quality and effectiveness drive
your medical care selection criteria and communicating to the work force
about the value in advance can go a long way in creating a positive response
and controlling Workers’ Compensation costs. |
