CMS releases dramatically revised final ACO regulations

The Centers for Medicare & Medicaid Services on Thursday released the final regulations for accountable care organizations (ACOs), which contain major revisions from the draft regulations released earlier this year.

The draft regulations, released in March, drew a firestorm of criticism, including complaints from providers that they would not share enough in the savings created by an ACO, a long and ill-defined list of 63 quality measures an ACO would need to meet in order to qualify for performance bonus payments and retrospective assignment of Medicare beneficiaries to ACOs.

Writing in the New England Journal of Medicine, CMS Administrator Donald Berwick, MD, noted that the final regulation’s “changes and numerous others create a more feasible and attractive on-ramp for a diverse set of providers and organizations to participate as ACOs.”

The changes came as a result of a strong and voluminous outpouring of more than 1,300 comments on the draft regulations that result in significant changes, notably:

  • Providers will not be required to share downside risk in order to participate in an ACO and will be able to earn revenue sharing based on ACO savings earlier as opposed to Medicare retaining all the initial savings.
  • Quality measures that ACOs will have to meet to qualify for performance bonuses have been reduced to 33 from 65.
  • Community health centers and rural health clinics, which were not allowed to form ACOs in the draft proposal, will be allowed to lead ACOs.
  • The ACOs will also be told up-front which Medicare beneficiaries are likely to be part of their system as opposed to not knowing which patients were in the ACO until the contract ended.

Reactions to the revisions among the medical community were generally positive.

“After preliminary review, the AMA believes this final rule includes a number of positive changes,” said Peter W. Carmel, MD, president, American Medical Association, in a statement. “The AMA recommended that the risk and payment structure for potential ACOs should encourage participation by physicians in all practice sizes, and we are very pleased that this rule allows ACOs to share in every dollar of cost savings and includes an option that limits financial risk, which is important for many physician practices.”

While the final rule reduced the number of quality measure by about half, Carmel added that “the AMA would have preferred even greater flexibility on which measures practices are required to report.”

Another concern addressed by the final rule was that smaller medical practices would lack the capital necessary to invest in technology and other infrastructure needed to create and participate in an ACO.
