Except for HIP, the United Nations Headquarters medical
insurance and dental insurance programmes are “experience-rated”. This
means the premiums each year are based on the cost of medical or dental
treatment received by UN participants in the prior year, plus the expected
effect of higher utilization and inflation, plus the appropriate allowance
for administrative expenses. The underlying elements in the cost of
health insurance for UN Headquarters programme participants are therefore
(1) continuing growth in utilization of services and medications, (2)
continuing increases in prices for services and medications, and (3)
expenses are incurred predominantly in the New York City area, which
is a high-cost health care market. In a year following a period of heavy
utilization, premium increases are likely to be relatively high. Conversely,
if utilization in the prior year has been moderate, the premium increase
in the subsequent year will likely be moderate. The yearly premiums
are calculated to meet medical expense and administration costs in the
forthcoming 12-month contract period. The underlying cost of medical
expenses is normally about 95% of the premium, and administrative expenses
make up the 5% remainder. Each year the expected overall costs of the
programme are first expressed as premiums and then borne collectively
by the participants and by the Organization in accordance with the sharing
ratios set by the General Assembly.
The HIP plan is “community-rated”. This means HIP premiums
are based on the average medical cost of all employers who purchase
the same kind of coverage from HIP, and not just that of United Nations
participants. The New York State Insurance Department regulates the
premium rates for community-rated programmes such as HIP.
