The Physician Group Practice (PGP) Transition Demonstration extended the PGP Demonstration, which concluded in March 2010. Through this initiative, CMS continued to test whether specific payment arrangements could help groups of physicians provide Medicare fee for service beneficiaries with high-quality, coordinated care.
The PGP Demonstration was the first pay-for-performance initiative for physicians under the Medicare program. Under the PGP Demonstration, physician group practices continued to be paid under regular Medicare fee schedules, but earned incentive payments for offering patients high-quality, coordinated healthcare that resulted in Medicare savings for the patient population they served.
CMS established benchmarks and quality improvement targets for each of the quality performance measures. In order to receive their full incentive payments, a group had to meet the quality performance benchmark. The PGP demonstration ran for five years, from April 2005 through March 2010.
Congress authorized the creation of a PGP Transition Demonstration to provide practices participating in the PGP demonstration with an opportunity to continue operating in similar arrangements in the Affordable Care Act. The PGP Transition demonstration began in January 2011 and concluded at the end of December 2012.
The PGP Transition Demonstration maintained many of the key features of the original PGP Demonstration, but included changes to policy that are also part of the Medicare Shared Savings Program or the testing of the Pioneer ACO Model by the Center for Medicare and Medicaid Innovation (Innovation Center).
Some of the major changes made by the PGP Transition Demonstration to the original PGP Demonstration include:
The PGP Transition Demonstration continued to use retrospective beneficiary assignment, meaning beneficiaries were assigned to participating physician group practices at the conclusion of the performance year, based on where they received care during the year. However, unlike the original PGP Demonstration, under the Transition Demonstration, participating practices had the option to choose one of two assignment methodologies:
- A two-step process that first assigned patients based on certain primary care services (E & M codes) from primary care physicians, and then utilized visits to specialists for those beneficiaries who did not receive services from primary care physicians, or
- A plurality of office and other outpatient service E & M codes regardless of specialty.
Under the PGP Demonstration, CMS compared the participating practice’s performance against a local comparison “control” group with respect to total per beneficiary expenditures for Medicare Parts A&B. Under the PGP Transition Demonstration, participating practices were compared against a national expenditure growth trend.
Percentage of Shared Savings
Under the PGP Demonstration, practices could share a maximum of 80 percent of savings they earned beyond the minimum savings requirement that was fixed at 2 percent. In the PGP Transition Demonstration, participating practices were permitted to share up to 50 percent of the savings after exceeding the minimum savings requirement which varied by the size of their patient population. Additionally, the participating practice’s performance on quality measures weighed more heavily on the total incentive payments than under the original PGP Demonstration.
Under the PGP Demonstration, CMS used a concurrent risk adjustment method to update benchmarks and expenditures. Under the PGP Transition Demonstration, CMS used the CMS- Hierarchical Conditions Category (CMS-HCC) prospective risk adjustment model to calculate beneficiary risk scores.
Participating PGP Transition Demonstration Practices
The following organizations participated in the Physician Group Practice Transition Demonstration:
- Billings Clinic (Billings, MT)
- Forsyth Medical Group (Winston-Salem, North Carolina)
- Geisinger Health System (Danville, PA)
- Marshfield Clinic (Marshfield, WI)
- Middlesex Health System (Middletown, CT)
- Mercy (formerly St. John’s Health System - Springfield, MO)
Pioneer ACO Model
Three of the original PGP Demonstration participating practices participated in the testing of the Pioneer ACO Model after participating in the Transition Demonstration in 2011:
- Dartmouth-Hitchcock (Lebanon, NH);
- Park Nicollet Health Services (St. Louis Park, MN); and
- University of Michigan (Ann Arbor, MI).
The testing of the Pioneer ACO Model began in January 2012.
