Health Plan Investigations
Last Updated: February 2025
Last Updated: February 2025
Service Provider Investigations. Generally, any service provider that exercises discretionary authority or discretionary control respecting the management or administration of an ERISA-covered health plan is a fiduciary. Many self-insured and most fully insured plans frequently include a health insurance issuer that exercises discretion or control over benefit claims decisions.
Issuers offering health insurance coverage in connection with group health plans are also subject to Part 7 provisions through parallel state and federal laws. States maintain primary enforcement authority over health insurance issuers regarding these rules.
Service provider investigations typically require an investigation of systemic ERISA violations to ensure service providers servicing ERISA-covered group health plans comply with plan documents and pay health benefits according to plan terms and applicable claims processing regulations. These cases focus on procedural, substantive, and disclosure violations related to the denial of promised health benefits. Though service provider cases may involve the same investigative issues as plan-level cases, they are generally more complex due to the large number of transactions involved (e.g., plan-wide patterns of claim processing errors).
Case Development. Enforcement strategies, annual operating plans, and National Office (NO) policy statements provide direction to identify areas of potential non-compliance and may emphasize the review and investigation of certain types of health investigations or issues. ROs should consider factors such as local economic conditions, geographical coverage within an RO’s jurisdiction, and specialized plan types.
Sources for potential health investigations include:
Written Investigative Plan. At the RD’s discretion, prepare investigative plans for cases in the form of a memorandum to the supervisor. A written investigative plan can help supervisors and Investigators/Auditors use limited resources productively. See Figure 1 for the suggested format for preparing the investigative plan.
Further, when working complex matters that are categorized as Major Cases, ROs should capture substantive case characteristics and track and document the development of case progress, as appropriate.
Investigative Activity. Health investigations should include a compliance review with all applicable ERISA provisions. The compliance review includes the following ERISA provisions:
Generally, the Investigator/Auditors should evaluate health plan/benefit package options offered for Part 7 compliance that includes an operational review of claims data, claims listings and/or claims.
Document Request Letters and Subpoenas. After case opening, the Investigator/Auditor may use a document request letter to request information beyond what is necessary to support information filed with the Secretary under Title I of ERISA. The document request letter requests the production of existing documents, not the creation of documents.
Letters may be sent to the health plan, plan sponsor, and health plan service providers, including but not limited to health insurance issuers and third-party administrators. The Investigator/Auditor may also send letters to the Plan or health insurance issuer requesting a comparative analysis demonstrating compliance with MHPAEA’s requirements pertaining to non-quantitative treatment limitations and related information required by the CAA.
Figure 3 is an example of a health plan document request letter. The information requested for a particular investigation may vary from this example depending on the facts and circumstances of the investigation.
Depending on the facts and circumstances, the Investigator/Auditor may send a subpoena in conjunction with or instead of a document request letter. In consultation with SOL and before a subpoena is issued, EBSA will request the minimum information necessary to accomplish its investigative objectives. See EM section on Subpoenas for more information.
Subsequent document requests or subpoenas may be necessary.
Health Oversight Authority. HIPAA privacy regulations, collectively known as the “Privacy Rule,” set forth several “permitted uses,” “disclosures,” or “standards” which allow covered entities to disclose protected health information (PHI) without patient authorization. The Privacy Rule’s “health oversight” standard enables EBSA to obtain PHI from plans, their service providers, and physicians as is necessary to ensure compliance with ERISA. EBSA is a health oversight agency.
ROs must follow special procedures when ROs request and receive PHI and information containing personally identifiable information (PII). ROs should coordinate with OE and PBSD or RSOL when requesting PHI to ensure proper procedures are followed. See EM section on Collection and Preservation of Evidence for more information about PHI.
No ERISA Violations Found. When the investigation does not identify any ERISA violation(s), the Investigator/Auditor will prepare a Closed ROI and a closing letter to be sent to plan officials. The RD will approve and sign all closing letters prior to issuance.
For further guidance on Voluntary Compliance letters closing letters, and Reports of Investigation, see the EM section on Voluntary Compliance Guidelines.
Action Reports of Investigation. The Investigator/Auditor will prepare an Action ROI together with exhibits and a cover memorandum whenever: (1) the RD determines that there are established violation(s) of Title I of ERISA that remain uncorrected, and (2) the litigation referral serves enforcement priorities.
The RO must send the approved Action ROI, cover memorandum, and exhibits to PBSD and RSOL. A copy of the approved and dated Action ROI, cover memorandum, and exhibits must be maintained in the case file.
Preparation of Action ROIs. An Action ROI should describe the facts obtained during the investigation and necessary to show each element of the alleged violations. The ROI should also set forth evidence, if any, that contradicts or does not support the elements of the violations. In addition, it should contain facts regarding each element of any applicable statutory or administrative exemption. The ROI should not state that all elements are met unless it also describes the facts that support that conclusion.
Every Action ROI must include both a list of exhibits attached to the Action ROI and a list of file material, documents, and workpapers maintained in the RO that were obtained or prepared during the investigation, but not exhibited. See Figure 5 for the format of an Action ROI.
The following general rules apply to the preparation of all ROIs:
RD Cover Memorandum Format. The RD’s cover memorandum must accompany each Action ROI and include:

RE:
xx Health Plan
Case No.
Dear Plan Administrator:
The Department of Labor has responsibility for the administration and enforcement of Title I of the Employee Retirement Income Security Act of 1974 (ERISA). Title I establishes standards governing the operation of employee benefit plans such as the xx Health Plan (the Plan).
The Plan is scheduled for investigation by this office. Investigative authority is vested in the Secretary of Labor by Section 504 of ERISA, 29 U.S.C. 1134, which states in part:
The Secretary [of Labor] shall have the power, in order to determine whether any person has violated or is about to violate any provision of this title or any regulation or order thereunder...to make an investigation, and in connection therewith to require the submission of reports, books, and records, and the filing of data in support of any information required to be filed with the Secretary under this title....
Additionally, the Plan will be examined for the purpose of determining whether it is complying with the laws contained in Part 7 of ERISA, including the Health Insurance Portability and Accountability Act of 1996, the Newborns’ and Mothers’ Health Protection Act, the Women’s Health and Cancer Rights Act, the Mental Health Parity and Addiction Equity Act, the Genetic Information Nondiscrimination Act, and the Patient Protection and Affordable Care Act and Health Care and Education Reconciliation Act (collectively, the Affordable Care Act). These laws amended Part 7 of ERISA and provide requirements for group health plans.
We have found in the past that submission of relevant documents to our office prior to the inception of an on-site field investigation can lessen the time subsequently spent with, and the administrative burden placed on, plan and corporate officials and may eliminate the need for an on-site visit entirely. To that end, we ask that you submit to this office, within ten business days of your receipt of this letter, the documentation listed on the enclosed Attachment A. If any items are not applicable, please so indicate and provide an explanation.
Thank you in advance for your cooperation. Should you have any questions, please contact the undersigned at XXX-XXX-XXXX.
Sincerely, Attachment
