Tracking Health Care Costs:
An Upswing in Premiums and Costs Underlying Health Insurance
Data Bulletin No. 20
November 2000
he great ride for employers, government and consumers,
during which health insurance premiums increased at unprecedented low rates,
is over. Premiums, which increased on average only 2 percent per year between
1994 and 1998, increased 8.3 percent in 2000 (see Figure
1). This sharp rise reflects both substantial increases in the costs underlying
insurance premiums and a steeper one in premiums associated with the health
insurance underwriting cycle (see Issue Brief No. 31).
For 2000, the premium increase for fully insured plans was
9.6 percent, in contrast to the 7.1 percent rise for self-insured plans.
This cyclical pattern is providing employers with another reason to
self-insure and to deemphasize plan types that are most commonly
fully insured, such as health maintenance organizations (HMOs).
In fact, the proportion of employees
in firms that self-insure rose from 48
percent to 51 percent between 1999
and 2000.

Underlying Cost Trends
The trend in costs underlying private health insurance premiums generally determines
the trend in premium costs over time. These costs rose by 6.6 percent in 1999,
up from an average increase of 2.4 percent per year from 1993 to 1997 (see
Figure 2).
The 1999 increase followed a pattern similar to prior years, with sharply
higher spending for drugs and hospital outpatient services, but small or negative
changes in hospital inpatient spending (see Figure 3).
- Drug spending accounted for 44
percent of the 1999 cost increase.
About one-third was due to higher
drug prices, the rest to new drugs
and increases in use of existing drugs.
- Hospital outpatient spending, which
accounted for 21 percent of the
increase, has grown at a consistently
high rate throughout the 1990s,
with annual per capita cost increases
averaging around 8.5 percent.
- Hospital inpatient spending accounted
for only 3 percent of the increase,
continuing the pattern of the last
half-decade, during which per capita
spending fell more often than it rose.
- Growth in physician spending, which
accounted for 32 percent of the cost
increase, dipped in the mid-1990s-
a period of substantial deflation in
physician fees paid by private insurers-
but by 1999 had nearly returned
to the levels seen earlier in the decade.

Implications for Consumers
These trends ultimately will affect consumers, who generally have been insulated
from cost increases in recent years. Out-of-pocket spending for medical services
and drugs declined throughout the 1990s, primarily because of a shift to managed
care and its richer benefit structure. Now that most people are in managed care,
out-of-pocket spending is likely to parallel premium trends.
During the late 1990s, employers absorbed a large portion of premium increases,
especially for those employees with single coverage. But should the economy
weaken, this trend could reverse. If that happens, sharp increases in employee
contributions to health coverage could exacerbate the growing problem of employees
with the lowest earnings not enrolling in plans for which they are eligible
and becoming uninsured (see Issue Brief No. 22). Prescription drugs is one area
where employees have not been insulated from rising costs, where very rapid
spending increases on pharmaceuticals have led many employers to increase copayments
for brand-name drugs that are not on their formularies.
Several factors indicate that spending increases will continue to be higher
than in recent years. These include responses to the managed care backlash,
expensive new technologies and provider consolidation. However, the large, double-digit
increases of the late 1980s and early 1990s are not likely to return. Todays
health care markets are more competitive, and price pressure on providers is
likely to lead to continuing efforts on their part to cut their costs.
This Data Bulletin is based on data
from the Milliman & Robertson
Health Cost Index, which is designed
to reflect cost increases faced by
private insurers; the Kaiser Family
Foundation/Hospital Research and
Education Trust survey of employer-based
health plans for 1998-2000;
and the KPMG survey of employer-based
health plans for 1993-1998.
