Payment Error Rate Measurement (PERM)

Current Audit

Maine is currently participating in a PERM audit for Reporting Year (RY) 2024 which covers randomly selected paid claims with a payment date from July 1, 2022 through June 30, 2023.

Error Rates

PERM is a federally contracted audit process that measures improper payments in Medicaid and Children's Health Insurance Program (CHIP) and produces error rates for each program. Error rates only indicate that a payment made did not meet statutory, regulatory, or administrative requirements; these are not fraud rates.

Financial Impact of Errors and Lack of Documentation

All errors are considered improper payments. Maine is required to reimburse the federal government for all improper payments and has the right to seek recoupment from those providers. See the PERM Audit: Common Errors (PDF) for errors found during the RY 2021 PERM audit cycle.
