Payment Error Rate Measurement (PERM)

The Payment Error Rate Measurement (PERM) is an audit program developed by the federal government to comply with law. The program examines eligibility decisions and payments to providers for Medicaid and Child Health Plan Plus (CHP+) for accuracy.

  • Colorado's next PERM cycle is federal fiscal year 2014 (October 2013 - September 2014).

Why is PERM required?

  • PERM helps the Department identify areas for improvement and helps cut down on fraud, waste and abuse.
  • PERM is required by federal law, the Improper Payments Information Act of 2002 (IPIA; Public Law 107-300).
  • Improper payment error rate and estimates of improper amounts must be reported.
  • Actions to reduce erroneous expenditures must be reported.

PERM Process

  • Colorado is one of 17 states that are audited once every three years, other states are audited in the off years.

How does PERM work?

  • Payment Reviews
  1. The Statistical Contractor uses a stratified random sampling design to draw the sample for review.
  2. The Review Contractor uses the sample list to request copies of medical records from the providers and reviews for medical necessity, correct coding, correct payment or denial of claims, and services actually provided.  
  • Eligibility Review
    • Eligibility determinations are reviewed for accuracy.

Eligibility Review

What is the purpose of the eligibility determination review?

  • The purpose of the eligibility review is to verify the eligibility of sampled cases using state eligibility criteria in effect at the time of the decision under review.

How will eligibility sites know if any of their eligibility determinations have been selected?

  • You will be contacted by the Department or our contractor to request copies of the case file.

What do eligibility sites need to do?

  1. Eligibility sites need to check if the case is currently undergoing investigation for fraud.  If so, this must be reported to the Department.
  2. Eligibility sites need to submit copies of the requested case file within 10 business days of the date of the request.  Original documentation will not be accepted.
  3. If the eligibility site is not the correct site, it should inform the Department of which site that has the requested case file information.

What happens if there is an error finding in the eligibility determination?

  • You will be contacted about the results of the case file review.  Eligibility sites may appeal the finding.  The appeal process is currently in development.

What about patient privacy?


Payment Review

Why are providers required to participate in PERM?

How will providers know if any of their claims have been selected?

  • You will be contacted for copies of your medical records to support the medical review.

What do providers need to do?

  • Providers need to submit all requested medical records and supported documents within 75 calendar days of the request date, either electronically or hard copies.
  • Providers need to update the Department with most current and accurate contact information.

Who will send the medical record request?

  • Our contractor will send out the request letters and, if necessary, follow-up letters and calls.  The Department will also send follow-up letters and make follow-up calls to the providers when necessary.
  • It is critical for the Department to have current and accurate contact information of providers to prevent any delay.

What happens if the provider does not cooperate?

  • Any claims for which documentation is not received upon request by the government shall be an overpayment subject to recovery.
  • The Department’s Program Integrity section will recover payments from medical records that have not been submitted or after the 75-day calendar due date.

What happens if there is an error finding in medical review?

  • Our contractor will notify the Department about the error, and the Department has the option to agree or disagree with its findings.

What happens if the Department disagrees?

  • The Department can file a request for a Difference Resolution and providers may be contacted to assist in the Difference Resolution process.

What if an error is confirmed?

  • States are required to return the federal share of overpayments. The Department will pursue recoveries as part of the corrective actions according to law and regulation.
