Physician Fee Schedule Final Rule November 1, 2018
The PFS final rule displayed in November 2018 addresses a subset of changes to the Medicare Shared Savings Program for Accountable Care Organizations (ACOs) proposed in the August 2018 proposed rule “Medicare Program; Medicare Shared Savings Program; Accountable Care Organizations Pathways to Success” and addresses various other revisions designed to update program policies under the Shared Savings Program. In order to ensure continuity of participation, finalize time-sensitive program policy changes for currently participating ACOs, and streamline the ACO core quality measure set to reduce burden and encourage better outcomes, CMS is finalizing the following policies:
- A voluntary 6-month extension for existing ACOs whose participation agreements expire on December 31, 2018, and the methodology for determining financial and quality performance for this 6-month performance year from January 1, 2019, through June 30, 2019.
- Reducing the Shared Savings Program core quality measure set by eight measures; and promoting interoperability among ACO providers and suppliers by adding a new Certified EHR Technology (CEHRT) threshold criterion to determine ACOs’ eligibility for program participation and retiring the current Shared Savings Program quality measure on the percentage of eligible clinicians using CEHRT.
- Allowing beneficiaries who voluntarily align to a Nurse Practitioner, Physician Assistant, Certified Nurse Specialist, or a physician with a specialty not used in assignment to be prospectively assigned to an ACO if the clinician they align with is participating in an ACO, as provided for in the Bipartisan Budget Act of 2018.
- Providing relief for ACOs and their clinicians impacted by extreme and uncontrollable circumstances in 2018 and subsequent years.
- Revising the definition of primary care services used in beneficiary assignment.

Shared Savings Program Proposed Rule August 9, 2018
CMS issued a proposed rule that would provide a new direction for the Shared Savings Program by establishing pathways to success through redesigning the participation options available under the program to encourage Accountable Care Organizations (ACOs) to transition to two-sided models (in which they may share in savings and are accountable for repaying shared losses). These proposed policies are designed to increase savings for the Trust Funds and mitigate losses, reduce gaming opportunities, and promote regulatory flexibility and free-market principles. The proposed rule also would provide new tools to support coordination of care across settings and strengthen beneficiary engagement; ensure rigorous benchmarking; promote interoperable electronic health record technology among ACO providers/suppliers; and improve information sharing on opioid use to combat opioid addiction.

Shared Savings Program Interim Final Rule for Extreme and Uncontrollable Circumstances December 26, 2017
CMS published an interim final rule with comment period (IFC) that established policies for assessing the quality and financial performance of Shared Savings Program ACOs affected by extreme and uncontrollable circumstances, such as Hurricanes Harvey, Irma, Maria, and the California wildfires, during Performance Year (PY) 2017. The IFC includes the following:
- CMS will use the same determination of an extreme and uncontrollable circumstance as determined under the Quality Payment Program, including the identification of affected geographic areas.
- ACOs with 20 percent or more of their assigned beneficiaries who reside in impacted counties, or an ACO legal entity located in impacted counties, will receive the higher of their ACO reported quality score or the mean Shared Savings Program ACO quality score.
- Performance-based risk ACOs will have any owed losses adjusted for the percent of the ACO’s assigned beneficiaries residing in impacted counties and the length of the emergency declaration.

Shared Savings Program Final Rule June 10, 2016
The new final rule published in June 2016 included the following:
- Revisions to the approach for resetting (or rebasing) an ACO's benchmark for a second or subsequent agreement period beginning on or after January 1, 2017 to take into account regional fee-for-service (FFS) expenditures.
- Revisions to the methodology for national FFS calculations to use assignable Medicare FFS beneficiaries (a subset of the broader FFS population) instead of all FFS beneficiaries.
- Addition of an option for ACOs participating under Track 1 to apply to renew for a second agreement period under a two-sided model (Track 2 or Track 3). If the ACO’s renewal request is approved, the ACO may request that its initial participation agreement under Track 1 be extended for an additional year (that is, the ACO would enter a fourth performance year under Track 1).

Shared Savings Program Final Rule June 9, 2015
The final rule improves several program areas including:
- Creates a new performance-based risk option (Track 3) that includes prospective beneficiary assignment, a higher sharing rate, and the opportunity to use new care coordination tools.
- Permits ACOs to participate in one additional 3-year agreement period under Track 1 and maintain the same maximum sharing rate applicable in their first agreement period.
- Establishes a waiver of the 3-day stay SNF rule for beneficiaries that are prospectively assigned to ACOs under Track 3.
- Streamlines the process for ACOs to access Medicare beneficiary claims data necessary for health care operations, while retaining the opportunity for beneficiaries to decline to have their claims data shared with the ACO.
- Refines the policies for resetting ACO benchmarks to help ensure that the program continues to provide strong incentives for ACOs to improve patient care and generate cost savings, and announces CMS’ intent to propose further improvements to the benchmarking methodology later this year.
- Revises the assignment methodology to remove certain specialty types whose services are not likely to indicate the provision of primary care services. Includes primary care services furnished by nurse practitioners, physician assistants, and clinical nurse specialists.
