The Lewin Group Will Continue to Support CMS Efforts to Measure Improper Payments in Medicaid and CHIP

Date Posted : May 29. 2019


The Lewin Group (Lewin) received a contract to continue to perform statistical, sampling and error rate calculations for the Centers for Medicare and Medicaid Services (CMS) Payment Error Rate Measurement (PERM) program. Lewin has been a proven resource for CMS’ statistical PERM program work under past contractual agreements. 

Lewin is honored to partner with CMS to assist in identifying opportunities to improve state Medicaid programs through the PERM program. With rising health care costs on everyone’s mind, Lewin is able to bring our years of expertise to provide CMS and states with actionable, data-driven insights that help improve health care programs that millions of Americans rely upon.

PERM measures claims and eligibility improper payments in state Medicaid fee-for-service and managed care, and Children’s Health Insurance Programs (CHIP) through statistical analysis of claims data, and the results of medical record, data processing and eligibility file reviews. Medicaid and CHIP program claims-level data are analyzed for consistency and compliance with federal legal and regulatory requirements. Lewin then works with CMS to produce a statistically valid error rate and reports that tell the story of the causes behind the error rates across programs and claims types.
