IRS Denies Tax Exemption to Commercial ACO
Health Care Insight
By T.J. Sullivan, Linda S. Moroney, Matthew Amodeo and Taylor R. Harrsion
On April 8, 2016, the IRS released a final adverse exemption determination with respect to an accountable care
organization (ACO) formed by an unnamed nonprofit health care system.[1] The adverse determination confirms and
elaborates on the view, first strongly implied by the IRS in Notice 2011-20,[2] that ACOs not participating in CMS’s
Medicare Shared Savings Program (MSSP) will face an uphill battle in qualifying for exemption from federal income tax.
ACOs do not provide health care services; rather, they integrate, coordinate and foster accountability for patient care among
likeminded health care providers in the ACO’s network. ACOs apply patient data collection and analytic tools, evidence
based medicine principles, and information sharing to improve individual patient outcomes and population health, and to
reduce the cost of care.
The Affordable Care Act established the MSSP to encourage health care providers to form ACOs,
and offer them the incentive of sharing in any Medicare program cost savings achieved through the MSSP. Recognizing the
potential benefits, health systems have established a significant number of ACOs in recent years, some to participate only
in the MSSP, others in arrangements with commercial insurance companies, and in some cases, both.
The ACO at issue in the recent IRS adverse determination was a strictly “commercial” ACO, meaning that it was formed to
negotiate with commercial payers and did not participate in the MSSP. Health care provider participants in the ACO
included physicians employed by the health system and its affiliates, and also included independent, community-based
providers who were unaffiliated with the health system.
These unaffiliated providers comprised approximately half of the
ACO’s participants. Aside from data collection and analysis, the ACO acted as the contracting agent for all participating
providers in the negotiation and execution of certain agreements with third-party commercial payers, linking rewards and
penalties to the achievement of certain quality goals and performance measures.
In applying existing federal tax exemption law and authorities to the ACO, the IRS first noted that the exempt charitable
purpose of lessening the burden of government, which it found helpful in Notice 2011-20, is not applicable to ACOs
operating outside of the MSSP. The IRS also noted that, while the promotion of health generally may be an exempt
charitable purpose, not all activities that promote health necessarily further exempt charitable purposes. In particular, the
IRS noted that the ACO’s negotiation with private health insurers on behalf of unrelated health care providers does not
further a charitable purpose because it provides primary benefits to the unrelated health care providers and only indirect
benefits to the public as a whole.
The IRS position is, essentially, that this ACO benefits the private interests of the
physicians more than incidentally, which precludes exemption.
While the analysis in the adverse determination letter should have no effect on ACOs formed solely to participate in the
MSSP, tax-exempt health systems are well-advised to carefully consider the structure of their commercial ACOs and the
potential tax ramifications. In particular, the adverse determination seems to indicate that an ACO’s participation in the
MSSP is a key factor in determining the ACO’s taxexempt status. The IRS also appears to be indicating that nonMSSP
ACOs comprised of large numbers of providers unaffiliated with the health system may preclude tax-exempt status. Further,
outside of the exemption determination context, the analysis relating to whether commercial ACO activities further an
exempt charitable purpose is likely to have implications in the context of unrelated business taxable income and, possibly,
tax-exempt bond financing.
This adverse determination could lead some providers to choose socalled “dual purpose” ACOs, formed to participate in
both the MSSP and commercial ACO arrangements, which could raise potential Antitrust and MSSP regulatory concerns.
This topic will be the focus of discussion in another Drinker Biddle client alert to be released shortly.
