Program integrity

  • PERM results:[8] Through the Payment Error Rate Measurement (PERM) program, HHS estimates Medicaid and CHIP improper payments on an annual basis, utilizing federal contractors to measure three components: FFS, managed care, and eligibility.  The PERM program uses a 17-state rotational approach to measure the 50 states and the District of Columbia over a three-year period.  Under this approach, each state is measured once every three years and national improper payment rates include findings from the most recent three-year cycle measurements.  Each time a cycle of states is measured, the new findings are utilized and the respective cycle’s previous findings are removed.  The FY 2019 national Medicaid improper payment rate estimate is 14.9 percent. The FY 2019 national improper payment rate estimate for CHIP is 15.83 percent. The FY 2019 improper payment rate for each Medicaid component is:
    • Medicaid FFS: 16.30 percent
    • Medicaid managed care: 0.12 percent
    • Medicaid eligibility: 8.36 percent
  • Program integrity recoveries: In FY 2017, total federal and state share Medicaid program integrity collections were approximately $785.1 million.
