CBO Releases Updated Estimates for the Insurance Coverage Provisions of the Affordable Care Act

Posted on
March 13, 2012

In preparing the March 2012 baseline budget projections, CBO and the staff of the Joint Committee on Taxation (JCT) have updated estimates of the budgetary effects of the health insurance coverage provisions of the Affordable Care Act (ACA)—the health care legislation enacted in March 2010. Those provisions:

  • Establish a mandate for most legal residents of the United States to obtain health insurance;
  • Create insurance “exchanges” through which certain individuals and families may receive federal subsidies to substantially reduce the cost of purchasing health insurance;
  • Significantly expand eligibility for Medicaid;
  • Impose an excise tax on certain health insurance plans with relatively high premiums;
  • Establish penalties on certain employers who do not provide minimum health benefits to their employees; and
  • Make other changes to prior law.

The most recent previous estimate of those effects was prepared in March 2011. For more details on the insurance coverage provisions of the ACA, you can see CBO’s cost estimate for the health care legislation, which was issued in March 2010.

The Estimated Net Cost of the Insurance Coverage Provisions Is Smaller Than Estimated in March 2011

CBO and JCT now estimate that the insurance coverage provisions of the ACA will have a net cost of just under $1.1 trillion over the 2012-2021 period-about $50 billion less than the agencies' March 2011 estimate for that 10-year period. (For comparison with previous estimates, these numbers cover the 2012-2021 period; estimates including 2022 can be found below.)

The net costs--specifically the combined effects on federal revenues and mandatory spending--reflect:

  • Gross additional costs of $1.5 trillion for Medicaid, the Children's Health Insurance Program (CHIP), tax credits and other subsidies for the purchase of health insurance through the newly established exchanges and related costs, and tax credits for small employers,
  • Offset in part by about $0.4 trillion in receipts from penalty payments, the new excise tax on high-premium insurance plans, and other budgetary effects (mostly increases in tax revenues).

Those amounts do not encompass all of the budgetary impacts of the ACA. They do not include federal administrative costs, which will be subject to future appropriation action. Also, they do not include the effects of the many other provisions of the law, including some that will cause significant reductions in Medicare spending relative to that under prior law and others that will generate added tax revenues relative those under prior law.

CBO and JCT have previously estimated that the ACA will, on net, reduce budget deficits over the 2012-2021 period; that estimate of the overall budgetary impact of the ACA has not been updated.

Gross Costs Are Higher, but Offsetting Budgetary Effects Are Also Higher

The current estimate of the gross costs of the coverage provisions—$1,496 billion through 2021—is about $50 billion higher than last year's projection; however, the other budgetary effects of those provisions, which partially offset those gross costs, also have increased in CBO’s and JCT’s estimates—to $413 billion—leading to the small decrease in the net 10-year tally.

Over the 10-year period from 2012 through 2021, enactment of the coverage provisions of the ACA was projected last March to increase federal deficits by $1,131 billion, whereas the March 2012 estimate indicates that those provisions will increase deficits by $1,083 billion.

The net cost was boosted by:

  • An additional $168 billion in estimated costs for Medicaid and CHIP, and
  • $8 billion less in estimated revenues from the excise tax on certain high-premium health insurance plans.

But those increases were more than offset by a reduction of:

  • $97 billion in the projected costs for the tax credits and other subsidies for health insurance provided through the exchanges and related spending
  • $20 billion in the projected costs for tax credits for small employers, and
  • $107 billion in deficits from the projected revenue effects of changes in taxable compensation and penalty payments and from other small changes in estimated spending.

The Revisions in Estimates Reflect Legislative, Economic, and Technical Changes

The major sources for the differences between the March 2011 and March 2012 projections are the following:

  • New Legislation. Several laws were enacted during the past year that changed the estimated budgetary effects of the insurance coverage provisions of the ACA.
  • Changes in the Economic Outlook. The March 2012 baseline incorporates CBO’s macroeconomic forecast published in January 2012, which reflects a slower recovery when compared with the forecast published in January 2011 (which was used in producing the March 2011 baseline).
  • Technical Changes. The March 2012 baseline incorporates updated projections of the growth in private health insurance premiums, reflecting slower growth than the previous projections. In addition, CBO and JCT made a number of other technical changes in their estimating procedures.

The Number of the Nonelderly Uninsured Is Higher Than Previously Estimated

CBO and JCT's projections of health insurance coverage have changed since last March. Fewer people are now expected to obtain health insurance coverage from their employer or in insurance exchanges; more are now expected to obtain coverage from Medicaid or CHIP or from nongroup or other sources. More are expected to be uninsured. The extent of the change in insurance coverage varies from year to year.

Compared with prior law, the ACA is now estimated by CBO and JCT to reduce the number of nonelderly people without health insurance coverage by 30 million to 33 million in 2016 and subsequent years, leaving 26 million to 27 million nonelderly residents uninsured in those years (see Table 3 at the end of the report). The share of legal nonelderly residents with insurance is projected to rise from 82 percent in 2012 to 93 percent in 2016 and subsequent years. That share rose to 95 percent in CBO and JCT's previous estimate.

According to the current estimates, from 2016 on, between 20 million and 23 million people will receive coverage through the new insurance exchanges, and 16 million to 17 million additional people will be enrolled in Medicaid and CHIP as a result of ACA. Also, 3 million to 5 million fewer people will have coverage through an employer compared with the number under prior law

Estimates Through Fiscal Year 2022

This report also presents estimates through fiscal year 2022, because the baseline projection period now extends through that additional year. The ACA’s provisions related to insurance coverage are now projected to have a net cost of $1,252 billion over the 2012-2022 period; that amount represents a gross cost to the federal government of $1,762 billion, offset in part by $510 billion in receipts and other budgetary effects (primarily revenues from penalties and other sources).

The addition of 2022 to the projection period has the effect of increasing the costs of the coverage provisions of the ACA relative to those projected in March 2011 for the 2012-2021 period because that change adds a year in which the expansion of eligibility for Medicaid and subsidies for health insurance purchased through the exchanges will be in effect. CBO and JCT have not estimated the budgetary effects in 2022 of the other provisions of the ACA; over the 2012-2021 period, those other provisions were previously estimated to reduce budget deficits.
