(1) Definitions.

"Authorized representative, " within the context of this rule, means the person appointed to carry out audit or review procedures, including assigned auditors, reviewers or agents contracted for specific audits, reviews, or audit or review procedures.

"Claim " means each record received by the department or the Iowa Medicaid enterprise that states the amount of requested payment and the service rendered by a specific and particular Medicaid provider to an eligible member.

"Clinical record" means a legible electronic or hard-copy history that documents the criteria established for medical records as set forth in rule 441-79.3 (249A). A claim form or billing statement does not constitute a clinical record.

"Confidence level" means the statistical reliability of the sampling parameters used to estimate the proportion of payment errors (overpayment and underpayment) in the universe under review.

"Customary and prevailing fee " means a fee that is both (1) the most consistent charge by a Medicaid provider for a given service and (2) within the range of usual charges for a given service billed by most providers with similar training and experience in the state of Iowa.

"Extrapolation " means that the total amount of overpayment or underpayment will be determined by using sample data meeting the confidence level requirement.

"Fiscal record" means a legible electronic or hard-copy history that documents the criteria established for fiscal records as set forth in rule 441-79.3 (249A). A claim form or billing statement does not constitute a fiscal record.

"Overpayment" means any payment or portion of a payment made to a provider that is incorrect according to the laws and rules applicable to the Medicaid program and that results in a payment greater than that to which the provider is entitled.

"Procedure code " means the identifier that describes medical or remedial services performed or the supplies, drugs, or equipment provided.

"Random sample " means a statistically valid random sample for which the probability of selection for every item in the universe is known.

"Underpayment" means any payment or portion of a payment not made to a provider for services delivered to eligible members according to the laws and rules applicable to the Medicaid program and to which the provider is entitled.

"Universe " means all items or claims under review or audit during the period specified by the audit or review.

(2) Audit or review of clinical and fiscal records by the department. Any Medicaid provider may be audited or reviewed at any time at the discretion of the department.
a. Authorized representatives of the department shall have the right, upon proper identification, to audit or review the clinical and fiscal records to determine whether:
(1) The department has correctly paid claims for goods or services.
(2) The provider has furnished the services to Medicaid members.
(3) The provider has retained clinical and fiscal records that substantiate claims submitted for payment.
(4) The goods or services provided were in accordance with Iowa Medicaid policy.
b. Requests for provider records by the Iowa Medicaid enterprise program integrity unit shall include Form 470-4479, Documentation Checklist, which is available atwww.ime.state.ia.us/Providers/Forms.html , listing the specific records that must be provided for the audit or review pursuant to paragraph 79.3(2) "J" to document the basis for services or activities provided.
c. Records generated and maintained by the department may be used by auditors or reviewers and in all proceedings of the department.
(3) Audit or review procedures. The department will select the method of conducting an audit or review and will protect the confidential nature of the records being audited or reviewed. The provider may be required to furnish records to the department. Unless the department specifies otherwise, the provider may select the method of delivering any requested records to the department.
a. Upon a written request for records, the provider must submit all responsive records to the department or its authorized agent within 30 calendar days of the mailing date of the request, except as provided in paragraph"b. "
b. Extension of time limit for submission.
(1) The department may grant an extension to the required submission date of up to 15 calendar days upon written request from the provider or the provider's designee. The request must:
1. Establish good cause for the delay in submitting the records; and
2. Be received by the department before the date the records are due to be submitted.
(2) For purposes of these rules, "good cause" has the same meaning as in Iowa Rule of Civil Procedure 1.977.
(3) The department may grant a request for an extension of the time limit for submitting records at its discretion. The department shall issue a written notice of its decision.
(4) The provider may appeal the department's denial of a request to extend the time limit for submission of requested records according to the procedures in 441-Chapter 7.
c. The department may elect to conduct announced or unannounced on-site reviews or audits. Records must be provided upon request and before the end of the on-site review or audit.
(1) For an announced on-site review or audit, the department's employee or authorized agent may give as little as one day's advance notice of the review or audit and the records and supporting documentation to be reviewed.
(2) Notice is not required for unannounced on-site reviews and audits.
(3) In an on-site review or audit, the conclusion of that review or audit shall be considered the end of the period within which to produce records.
d. Audit or review procedures may include, but are not limited to, the following:
(1) Comparing clinical and fiscal records with each claim.
(2) Interviewing members who received goods or services and employees of providers.
(3) Examining third-party payment records.
(4) Comparing Medicaid charges with private-patient charges to determine that the charge to Medicaid is not more than the customary and prevailing fee.
(5) Examining all documents related to the services for which Medicaid was billed.
e. Use of statistical sampling techniques. The department's procedures for auditing or reviewing Medicaid providers may include the use of random sampling and extrapolation.
(1) A statistically valid random sample will be selected from the universe of records to be audited or reviewed. The sample size shall be selected using accepted sample size estimation methods. The confidence level of the sample size calculation shall not be less than 95 percent.
(2) Following the sample audit or review, the statistical margin of error of the sample will be computed, and a confidence interval will be determined. The estimated error rate will be extrapolated to the universe from which the sample was drawn within the computed margin of error of the sampling process.
(3) Commonly accepted statistical analysis programs may be used to estimate the sample size and calculate the confidence interval, consistent with the sampling parameters.
(4) The audit or review findings generated through statistical sampling procedures shall constitute prima facie evidence in all department proceedings regarding the number and amount of overpayments or underpayments received by the provider.
f. Self-audit. The department may require a provider to conduct a self-audit and report the results of the self-audit to the department.
(4) Preliminary report of audit or review findings. If the department concludes from an audit or review that an overpayment has occurred, the department will issue a preliminary finding of a tentative overpayment and inform the provider of the opportunity to request a reevaluation.
(5) Disagreement with audit or review findings. If a provider disagrees with the preliminary finding of a tentative overpayment, the provider may request a reevaluation by the department and may present clarifying information and supplemental documentation.
a. Reevaluation request. A request for reevaluation must be submitted in writing within 15 calendar days of the date of the notice of the preliminary finding of a tentative overpayment. The request must specify the issues of disagreement.
(1) If the audit or review is being performed by the Iowa Medicaid enterprise surveillance and utilization review services unit, the request should be addressed to: IME SURS Unit, P.O. Box 36390, Des Moines, Iowa 50315.
(2) If the audit or review is being performed by any other departmental entity, the request should be addressed to: Iowa Department of Human Services, Attention: Fiscal Management Division, Hoover State Office Building, 1305 E. Walnut Street, Des Moines, Iowa 50319-0114.
b. Additional information. A provider that has made a reevaluation request pursuant to paragraph"a" of this subrule may submit clarifying information or supplemental documentation that was not previously provided. This information must be received at the applicable address within 30 calendar days of the mailing of the preliminary finding of a tentative overpayment to the provider, except as provided in paragraph"c" of this subrule.
c. Disagreement with sampling results. When the department's audit or review findings have been generated through sampling and extrapolation and the provider disagrees with the findings, the burden of proof of compliance rests with the provider. The provider may present evidence to show that the sample was invalid. The evidence may include a 100 percent audit or review of the universe of provider records used by the department in the drawing of the department's sample. Any such audit or review must:
(1) Be arranged and paid for by the provider.
(2) Be conducted by an individual or organization with expertise in coding, medical services, and Iowa Medicaid policy if the issues relate to clinical records.
(3) Be conducted by a certified public accountant if the issues relate to fiscal records.
(4) Demonstrate that bills and records that were not audited or reviewed in the department's sample are in compliance with program regulations.
(5) Be submitted to the department with all supporting documentation within 60 calendar days of the mailing of the preliminary finding of a tentative overpayment to the provider.
(6) Finding and order for repayment. Upon completion of a requested reevaluation or upon expiration of the time to request reevaluation, the department shall issue a finding and order for repayment of any overpayment and may immediately begin withholding payments on other claims to recover any overpayment.
(7) Appeal by provider of care. A provider may appeal the finding and order of repayment and withholding of payments pursuant to 441-Chapter 7. However, an appeal shall not stay the withholding of payments or other action to collect the overpayment. Records not provided to the department during the review process set forth in subrule 79.4(3) or 79.4(5) shall not be admissible in any subsequent contested case proceeding arising out of a finding and order for repayment of any overpayment identified under subrule 79.4(6). This provision does not preclude providers that have provided records to the department during the review process set forth in subrule 79.4(3) or 79.4(5) from presenting clarifying information or supplemental documentation in the appeals process in order to defend against any overpayment identified under subrule 79.4(6). This provision is intended to minimize potential duplication of effort and delay in the audit or review process, minimize unnecessary appeals, and otherwise forestall fraud, waste, and abuse in the Iowa Medicaid program. This rule is intended to implement Iowa Code section 249A.4.
