Special Investigative Unit Wellpoint Texas
Learn how the AI-generated research projects were createdOverall Conclusion
The Wellpoint Texas SIU did not consistently comply with state and contractual requirements related to preventing, detecting, and investigating fraud, waste, and abuse and reporting reliable information on SIU activities, results, and recoveries to the Texas Health and Human Services Office of Inspector General. Despite dedicating 10 full-time staff and one full-time manager and maintaining processes to conduct investigations, these resources were not effective and resulted in recoveries of $426,467 and $12.8 billion in medical claims paid during the audit period.

SIU activities for Texas Medicaid and CHIP from September 1, 2021 through August 31, 2023.
Key Findings Summary
CHIP-specific data mining or investigations were not conducted; Wellpoint did not perform CHIP-focused data mining/analysis or investigations.
Wellpoint did not consistently document that all required elements of preliminary investigations were completed or that investigations were conducted within the required timelines (39 of 50 sampled preliminary investigations lacked supporting documentation; 11 with all elements completed, only 3 completed beyond the required timeline).
In extensive investigations, Wellpoint did not complete elements within the required timeframes in 17 of 23 cases (74 percent); one case lacked documentation showing the sample size met minimum requirements.

AI Scope Summary
This audit underscores the need for CHIP-specific data mining and investigations, timely and well-documented preliminary and extensive investigations, and accurate reporting to OIG. For future Medicaid audits, emphasis should be placed on CHIP data isolation, complete documentation of all required investigation elements within 15 working days for preliminary reviews and 15/45/15 timelines for samples and records, and accurate, timely reporting of SIU activity and outcomes to OIG, with enhanced data governance and clear escalation channels for technical reporting issues.
AI-Generated Insight
The SIU program at Wellpoint shows substantial compliance gaps, particularly in CHIP-specific data activities, timely investigation documentation, and data reporting integrity. Data reliability issues undermine audit conclusions and highlight the need for stronger data governance, tailored training, and robust export/reporting controls to ensure accurate reflection of investigations and recoveries.
Audit Objectives
Evaluate the effectiveness of Wellpoint’s Special Investigative Unit (SIU) in preventing, detecting, and investigating fraud, waste, and abuse.
Evaluate whether Wellpoint reports reliable information on SIU activities, results, and recoveries to the Texas Health and Human Services Office of Inspector General.
Scope of the audit covered SIU activities for Texas Medicaid and CHIP for the period September 1, 2021, through August 31, 2023.
Audit Findings (8)
CHIP-specific data mining or investigations were not conducted; Wellpoint did not perform CHIP-focused data mining/analysis or investigations.
Wellpoint did not consistently document that all required elements of preliminary investigations were completed or that investigations were conducted within the required timelines (39 of 50 sampled preliminary investigations lacked supporting documentation; 11 with all elements completed, only 3 completed beyond the required timeline).
In extensive investigations, Wellpoint did not complete elements within the required timeframes in 17 of 23 cases (74 percent); one case lacked documentation showing the sample size met minimum requirements.
Wellpoint did not maintain supporting documentation for the sample size in one investigation.
There were inconsistencies between Wellpoint’s internal case management data and what was reported to OIG: Wellpoint’s CM system showed 418 investigations with $16.7 million identified overpayments, while the OIG-reporting showed 413 investigations with $11.65 million identified overpayments; recoveries differed ($428,069 vs $426,467).
Wellpoint reported 418 investigations in its system but 189 leads were not reported to OIG; some leads were not considered preliminary investigations, though documentation showed some activities.
Data elements in the case management system and OIG reports were missing or inaccurate, limiting the reliability of the data used for this audit.
Fraud, waste, and abuse training was not tailored to employees’ or subcontractors’ specific job functions.
Recommendations (5)
Wellpoint must perform required SIU activities for CHIP including data mining, data analysis and fraud, waste, and abuse investigations.
For preliminary investigations, Wellpoint should improve processes and controls to (a) perform and document all required elements, and (b) complete investigations within required timeframes.
Wellpoint should strengthen processes to meet and document the following timelines: selection of provider claims samples within 15 working days of completing a preliminary investigation with suspicious indicators; requests for medical records and encounter data within 15 working days of sample selection; review of records within 45 working days of receipt; and ensure sample size requirements are met.
Wellpoint should improve processes and controls to capture all required data accurately in its case management system, report complete and accurate information on the MCO Open Case List Report, and provide feedback and request technical assistance from OIG promptly.
For personnel involved in data collection, provider enrollment or disenrollment, encounter data, claims processing, utilization review, quality assurance, and marketing for Medicaid or CHIP, Wellpoint must provide training tailored to their areas of responsibility.
