OPTUMSERVE HEALTH SERVICES, INC.

OptumServe Health Services received a contract modification on award HT001119D0002 that grew 429 times in value, vastly exceeding the 11.5-fold average growth rate for peers in the same NAICS code. The entity also concentrates heavily on sole-source awards, winning 24 of 36 total awards without competition, compared to a median of zero sole-source awards among 47 peer organizations in ambulatory health services. A multivariate outlier detection flagged the entity as moderately anomalous based on its combination of high total dollars, award count, modification frequency, and low competition ratio. Benford's law analysis of leading digits showed no significant deviation from expected patterns.

The modification growth z-score reached 12.19 sigma, indicating extreme statistical rarity. The entity's sole-source concentration z-score was 4.58 sigma, placing it in the 97th percentile of suspicion. Over its lifetime, OptumServe accumulated 548.9 million dollars across 36 awards, with 88.9 percent of awards receiving modifications. The isolation forest anomaly score was 0.649 on a 0-to-1 scale. Benford's test yielded a p-value of 0.41, showing no digit-frequency concern.

These detectors identify statistical outliers, not confirmed fraud. The extreme modification growth may reflect legitimate contract scope expansion in healthcare services delivery, particularly given HHS's role in pandemic response and emergency health initiatives. The high sole-source concentration warrants scrutiny but could reflect specialized service requirements or incumbent advantages. The small peer group of 47 entities in this NAICS category limits the robustness of comparative benchmarks.
