Dear Senator:
This letter responds to your request for additional information about the
provisions of the Patient Protection and Affordable Care Act (PPACA,
Public Law 111-148) regarding high-risk insurance pools.
PPACA appropriated $5 billion for the Department of Health and Human
Services (HHS) to implement a temporary program to operate such pools.
To be eligible to enroll, applicants must have been uninsured for at least
6 months and must have a preexisting medical condition. Enrollees will be
charged a standard premium--one that is based on the expected costs of
covering a broadly representative population, rather than the costs of
covering high-risk enrollees. Federal subsidies to the pools will cover the
difference between the enrollees' premiums and the costs of providing their
insurance. The program is scheduled to commence later this year and may
continue to operate through 2013 (after which time qualified enrollees
could switch to a health plan offered through newly created insurance
exchanges).
In its analysis of PPACA released in March, the Congressional Budget
Office (CBO) estimated that all of the $5 billion appropriated for the
program would be spent.1 CBO concluded that the new pools would be
more attractive than the high-risk pools that now exist in many states, both
because the premium would be lower (state high-risk pools typically charge
a premium between 125 percent and 200 percent of the standard premium)

and because the new pools would provide immediate coverage for
enrollees' preexisting medical conditions (current high-risk pools generally
do not do so). Reflecting that assessment, CBO estimated that the funding
available for subsidies would not be sufficient to cover the costs of all
applicants through 2013, so CBO assumed that HHS would use the
authority given to it under the act to limit enrollment in the program. On
that basis, CBO expects that the number of enrollees in the program will
average about 200,000 over the 2011­2013 period. If, instead, more people
are allowed to sign up initially, the available funds will probably be
exhausted prior to 2013, but total spending for the program will still be
capped at $5 billion.
You also asked about the federal costs of implementing a similar program
for high-risk pools that did not cap the funding available. Estimating those
costs is difficult not only because of the uncertainty surrounding the
number and types of people who would want to enroll but also because
several of the program's features have not been precisely defined. For
example, the new high-risk pools are supposed to cover at least 65 percent
of enrollees' costs for health care, on average, but could cover a higher
share. The larger the share of costs that the program would cover, the more
attractive it would be to potential enrollees and the more expensive it would
be to implement--because there would be more enrollees and higher costs
per enrollee. Similarly, the law provides little guidance about how the
requirement for participants to have a preexisting condition will be met,
how applicants' lack of insurance coverage will be monitored, and how the
program will interact with existing high-risk pools. The resulting
uncertainty about the program's design did not affect CBO's cost estimate
with the $5 billion funding cap in place, but how those features are
ultimately defined would affect the estimated cost of an uncapped program.
At this point, therefore, CBO can provide only a preliminary range of
estimates reflecting some assumptions about an uncapped program's
specifications. If the program covered about 65 percent of enrollees' costs
for health care, federal spending through 2013 would probably fall between
$10 billion and $15 billion--or $5 billion to $10 billion more than the cap
specified in PPACA. Total enrollment in the federal high-risk pool program
would be expected to grow from roughly 400,000 in 2011 to about 600,000
or 700,000 in 2013.

Several factors affect the estimate of enrollment. The number of people
who may be eligible for the program is in the millions--much greater than
the estimates of participation--but CBO focused its analysis on those
people who would be likely to enroll and has not estimated the total size of
the eligible population. In the absence of the program, most of those
enrollees would have been uninsured, but some would have had coverage
from an individually purchased or employment-based plan. (Reductions in
employment-based coverage tend to raise federal revenues because that
coverage receives favorable tax treatment, but CBO has not estimated the
effects of an uncapped program on revenues.) Although enrollees will be
subsidized, many potential applicants will be discouraged from enrolling by
the premium they would have to pay and the cost-sharing requirements they
would face in the program. Others might be eligible for the program but not
aware of it.
I hope that this analysis is helpful. If you have any questions, please contact
me or CBO staff. The primary staff contacts for this analysis are Philip Ellis
and Holly Harvey.
Sincerely,
Douglas W. Elmendorf
Director
