An ACO may contract with both public and private payors. Even if an ACO initially plans to contract only with private payors, the ACO may choose to organize in a manner to comply with the federal regulations to provide flexibility for future contracting with public payors and to address the antitrust compliance risk of ACO contracting procedures.

Choice of Entity and Corporate Structure. Federal regulations do not dictate the type of legal entity for ACO formation, but they do require that the ACO be a legal entity with a federal taxpayer identification number (TIN). There are many considerations in selecting the choice of entity and related affiliates of an ACO. Most North Carolina ACOs have been organized as limited liability companies (LLCs) due to the flexibility that LLCs can offer. Further, there are a host of other issues entities must consider in organizing and structuring an ACO (e.g., whether the ACO is to be wholly owned by a tax-exempt entity, whether it is to be jointly owned by multiple providers, whether a separate affiliate is to provide management services to the ACO, etc.).

ACO Issues for Tax-Exempt Entities. Tax-exempt entities that participate in ACOs will want to understand the potential tax consequences of having an ownership interest in an ACO. ACOs are often organized as LLCs that are classified as partnerships for tax purposes. If classified as a partnership, the LLC’s items of income and loss flow through to its members and are reported on their income tax returns. The activities of an LLC treated as a partnership for tax purposes are considered to be the activities of a nonprofit organization that is an owner of the LLC when evaluating whether the nonprofit is operated exclusively for exempt purposes within the meaning of IRC Section 501(c)(3). Similarly, the activities of such an LLC are attributed to its nonprofit partners in determining whether they are engaged in an unrelated trade or business that may produce unrelated business taxable income.

In Notice 2011-20, the IRS solicited comments as to whether existing guidance governing tax-exempt organizations is sufficient for those planning to participate in the MSSP through an ACO. The IRS also made the following statements in the Notice:

The Notice does not address whether an exempt organization’s participation in non-MSSP activities through an ACO will be consistent with the organization’s tax-exemption or will not result in unrelated business income tax. The IRS, however, requested comments regarding those issues.

Choice of Owners. A threshold decision in ACO formation is to define the scope of the owners of the ACO. Capital formation may influence the extent to which physicians, as compared to hospitals and health systems, are owners in the ACO. To some extent, the financial benefits of ACO operations and performance can be shared with participating providers even if they are not owners through the allocation of shared savings payments. For a hospital or health system, a structure without physician ownership allows ACO start-up costs to be paid by the hospital/health system without the requirement for any pro rata contribution by physicians. On the other hand, physician ownership can be key to achieving the real aims and operational success of an ACO or other clinically integrated network. Indeed, federal regulations require all participants to demonstrate a “meaningful commitment” to the ACO, and these regulations identify financial investment as one example of meaningful commitment. A hybrid model, in which the institutional investors provide the bulk of initial capital and receive equity interests with priority over the equity interests of those who do not provide as much capital, may also be considered. Another option is for the ACO to be owned by the larger institution with better access to capital, with management and administrative services provided by a management service organization that includes physician ownership.

To the extent that ownership of the ACO is offered to a large number of physicians or other providers, the ACO will need to comply with securities laws applicable to private and public offerings. At some point, the number of security holders can become so large that the ACO becomes subject to public company filing requirements.

Governance. Federally contracted ACOs must satisfy detailed governance requirements. The ACO must have an identifiable governing body, unique to the ACO, which is responsible for overseeing the ACO’s activities and charting its strategic direction. Absent CMS’ approval to an exception to this general rule, ACO participants must have 75% control of the governing body, and the governing body must include a Medicare beneficiary representative. ACOs also are required to have an administrative officer that manages the ACO’s operations and activities, and a board certified medical director who oversees the ACO’s clinical programs and initiatives. Typically, ACOs will establish additional provider-led committees to identify opportunities to reduce costs or improve quality, create clinical guidelines, and oversee adherence to those guidelines. ACOs are required to have a conflict-of-interest policy, and must have a compliance plan with a compliance officer who is different from the person serving as legal counsel to the ACO.

The ACO application requires submission of the ACO's charter and governing documents, executive job descriptions, committee charters and other materials, all of which are aimed at allowing CMS to determine whether the applicant has a leadership and management structure that includes clinical and administrative systems to promote evidence-based medicine. These requirements are also based, in part, on addressing antitrust issues by requiring a governance structure that allows a degree of clinical integration sufficient to justify group contracting at the ACO level.

The governance process during ACO formation is also integral to qualify for applicable waivers under the federal fraud and abuse laws (i.e., the laws and regulations relating to Stark, Anti-Kickback, and Civil Monetary Penalties), which were adopted to allow ACO formation. ACOs must qualify for the waivers so that the ACOs can distribute the shared savings payments among the ACO participants and providers. To qualify, the ACO’s governing body must make certain express determinations, and those determinations must be supported by contemporaneous written documentation. It is important that the governing body take certain action during the organization process of the ACO.

Network Formation. During the start-up phase of an ACO, the ACO engages in broad recruitment efforts to contract with participating providers via provider agreements. The MSSP regulations distinguish between ACO participants and providers. Participants are individual providers or groups of providers that have a Medicare-enrolled TIN and are eligible to bill for Medicare services, which alone or together comprise the ACO. For example, ACO participants might include group practices, acute care hospitals, solo practices, qualified health centers or rural health centers. CMS uses the TINs of ACO participants as a basis for establishing eligibility, assignment of beneficiaries, computation of the ACO’s performance benchmark, and quality assessment. ACO providers are individuals or entities that are Medicare-eligible providers that bill for services under the TIN of an ACO participant. MSSP applications must include a list of ACO participants and ACO providers. The ACO application process requires that agreements with participants and providers be signed prior to submission of the application, and these agreements must comply with the MSSP regulations. If accepted into the MSSP, the ACO must then notify CMS within thirty days of changes in the list of participants and providers.

All ACOs will enter into participating provider agreements with primary care and specialist physicians and other providers. In ACOs sponsored by health systems, the health system may be the exclusive hospital provider in the ACO within its geographic area and capabilities. But the reverse is generally not true, i.e., the hospital is not restricted from contracting with other ACOs. In fact, to fall in the antitrust safety zone described below, hospitals need to be allowed to contract independently with payors and other ACOs.

A key consideration in network formation of any type is the sufficiency of the network, but for ACOs, this consideration is especially important. The aim of the ACO is to improve the quality of care and clinical outcomes of the beneficiaries assigned to the ACO. The ACO must have authority to influence clinical protocols and to promote evidence-based medicine across a continuum of essential providers in a patient’s care. Thus, the choice of quality providers (ideally, with some electronic medical record and data reporting capabilities) can be important.

The federal regulations require that primary care services be provided on an exclusive basis to only one ACO. CMS has responded to several criticisms about this exclusivity requirement, probably because it is so different from the realm of IPA and PHO formation where non-exclusivity is the norm. CMS explains that exclusivity is required for physicians billing under primary physician care codes for purposes of beneficiary assignment. Otherwise, CMS cannot attribute shared savings to one ACO if these services are provided by physicians through multiple ACOs. Exclusivity is determined by TINs, not NPI numbers. The primary care physicians include internal medicine, geriatrics, family practice and general practice, but an ACO also needs to check the HCPCS codes issued by CMS since some specialists may also bill under these codes.

The CMS application process will include a review of the ACO’s remedial process for dealing with providers who do not meet performance standards via correction measures and expulsion.

Each ACO participant must demonstrate a “meaningful commitment” via financial contributions or human investment in ACO programs and committees and via an agreement to follow policies and be subject to corrective measures and expulsion for failure to do so.

Antitrust. When competing health care providers jointly negotiate with payors, through an ACO or otherwise, they need to avoid violating antitrust laws, which bar competitors from conspiring to set prices or engaging in other anticompetitive conduct. Networks, like IPAs and PHOs, are accustomed to addressing antitrust issues through financial risk-sharing and clinical integration in accordance with the Statements of Antitrust Enforcement Policy in Health Care, jointly adopted by the Department of Justice (DOJ) and Federal Trade Commission (FTC) in 1996.

ACOs present some unique antitrust issues, and the DOJ and FTC have adopted an additional Statement addressing the agencies’ antitrust enforcement policy for ACOs (ACO Antitrust Statement). Price fixing is not a concern for federally contracted ACOs since CMS sets Medicare Part A and Part B payment rates, but it is a concern with ACOs that contract with private payors. Recognizing that ACOs’ potential to improve quality and reduce costs generally will offset any harm to competition resulting from joint contracting, the ACO Antitrust Statement includes an antitrust safety zone for ACOs marketed to private payors that qualify for and participate in the MSSP, satisfy certain market share requirements (generally by having 30% or less market share except in rural areas), and whose ambulatory surgical center and hospital members are non-exclusive to the ACO.
ACOs that do not satisfy the safety zone requirements will be subject to scrutiny under the “rule of reason,” which assesses whether the procompetitive effects of a restraint on trade are likely to outweigh any associated harms to competition. The ACO Antitrust Statement identifies several types of conduct by ACOs that will receive particularly close scrutiny under the rule of reason, including (1) sharing competitively sensitive information; (2) preventing payors from establishing incentives for their enrollees to choose certain providers; (3) tying sales of ACO services to the purchase of goods and services of providers outside the ACO (and vice versa); (3) exclusive contracting with ACO care providers (with the exception of primary care physicians, who must be exclusive to one ACO); and (5) restricting payors’ abilities to make cost, quality and efficiency data available to their enrollees.

Fraud and Abuse. An ACO must consider the applicability of federal fraud and abuse laws, such as the Stark Law, the Anti-Kickback Statute and the Civil Monetary Penalties Law. These laws generally prohibit certain physician self-referrals, compensation in exchange for referrals and providing inducements to beneficiaries of a federal health care program. CMS has recognized that the restrictions that federal fraud and abuse laws place on certain arrangements between hospitals, physicians and other entities may impede the ability of an ACO to participate in the MSSP. For instance, payments of shared savings to employed physicians may not satisfy the requirement of the Stark Law employment exception that compensation be based on personally performed and identifiable services if the physician receives shared savings payments for patients who the physician did not see. As a result, CMS has adopted five waivers when applying federal fraud and abuse laws to ACOs: the Pre-Participation Waiver, the Participation Waiver, the Shared Savings Waiver, the Compliance with Stark Law Waiver, and the Patient Incentive Waiver.

The fraud and abuse waivers apply to certain costs incurred and payments made by an ACO during its preformation stage, during the time period when it is under contract with CMS and during the post-contract stage. The Pre-Participation Waiver permits an ACO participant to fund ACO start-up costs and development without liability under certain federal fraud and abuse laws. The Participation Waiver allows an ACO participant to undertake certain actions during the term of the ACO’s participation agreement that might otherwise implicate the federal fraud and abuse laws. The Shared Savings Waiver permits the distribution of shared savings received by the ACO. The Compliance with Stark Law Waiver protects arrangements that meet an existing exception to the Stark Law from liability under the anti-kickback laws or civil monetary penalties law. Finally, the Patient Incentive Waiver allows an ACO to offer its beneficiaries non-monetary incentives to encourage preventive care and compliance with treatment regimes.

In order to qualify for a waiver, an ACO arrangement must be reasonably related to the purposes of the MSSP. Furthermore, arrangements that fall under an existing exception to federal fraud and abuse laws need not qualify for a waiver. The waivers are self-implementing, meaning an ACO does not need to apply to CMS or any other government body for approval.
