One Call Buys Data Dimensions, Forging a New Digital Workers' Comp Era

ST. LOUIS, MO – April 16, 2026 – In a significant move poised to reshape the workers' compensation landscape, care management leader One Call has acquired Data Dimensions, a specialized technology and electronic data interchange (EDI) provider. The transaction, announced following the sale by private equity firm Thompson Street Capital Partners (TSCP), marks a pivotal step toward creating a fully integrated digital ecosystem for an industry long challenged by fragmentation and manual processes.

The deal, for which financial terms were not disclosed, brings Data Dimensions' advanced automation and data exchange capabilities into One Call's extensive ancillary care network. This integration promises to create the industry's first end-to-end infrastructure connecting everything from patient intake and clinical coordination to data exchange and payments, aiming to reduce friction and improve outcomes for millions of injured workers annually.

A Strategic Play to Digitize Workers' Compensation

One Call stands as a dominant force in the workers' compensation market, coordinating a comprehensive suite of ancillary services—including physical therapy, diagnostics, and durable medical equipment—for approximately one million injured workers each year. The company's strategic focus has increasingly shifted toward leveraging technology to build a more connected and efficient platform. The acquisition of Data Dimensions is the cornerstone of this vision.

The workers' compensation industry has historically been burdened by disjointed systems, requiring multiple administrative handoffs between payers, providers, and care coordinators. This fragmentation often leads to delays in care, billing inaccuracies, and a heavy administrative load for all parties. One Call's acquisition directly targets these pain points by absorbing Data Dimensions' specialized technology stack.

Founded in 1982, Data Dimensions has built a robust platform providing an EDI clearinghouse network, digital mailroom intake, and electronic payment processing for the healthcare, insurance, and government sectors. Its solutions are designed to simplify complex billing and documentation workflows. By integrating these capabilities, One Call aims to create a single, continuous digital thread throughout the care and claims journey. This unified system is expected to streamline workflows between payers and providers, enhance the transparency of documentation, and drive greater operational consistency across the board.

For injured workers, the integration promises a smoother, more predictable recovery path with fewer administrative hurdles. For providers, it offers the potential for simplified routing, reduced paperwork, and faster payments. For payers, the benefits lie in enhanced efficiency, greater visibility into the claims process, and improved cost management through automation.

The Private Equity Playbook in Action

The sale marks a successful exit for Thompson Street Capital Partners, the St. Louis-based private equity firm that acquired Data Dimensions in 2019. The partnership exemplifies TSCP's investment strategy: identifying promising founder-owned, middle-market businesses and accelerating their growth through strategic investment and operational support.

During its ownership, TSCP worked with the Data Dimensions management team to significantly enhance the company's value proposition. This involved bolstering its core clearinghouse capabilities, expanding its digitalization and workflow automation offerings, and executing key strategic acquisitions. The purchases of WorkCompEDI and Providerflow, in particular, deepened Data Dimensions' expertise and technological footprint specifically within the complex workers' compensation space, making it a highly attractive asset for a market leader like One Call.

“Data Dimensions has built a differentiated platform at the intersection of healthcare, insurance and technology,” said J.C. Wetzel, Managing Director at TSCP, in a statement. “Over the course of our partnership the company expanded its capabilities, deepened its customer relationships and reinforced its position as a mission-critical partner in complex, tightly regulated environments. We believe Data Dimensions is well-positioned for continued growth.”

This successful exit underscores a common theme in TSCP's portfolio, where the firm leverages its expertise to build market-leading companies in specialized sectors like healthcare and technology before transitioning them to strategic buyers capable of taking them to the next stage of growth.

Consolidation and Competition in a Complex Market

This acquisition is not happening in a vacuum. It reflects a broader trend of consolidation within the health tech and insurtech sectors, where scale and integrated platforms are becoming critical competitive differentiators. By combining One Call's vast network and care management expertise with Data Dimensions' data and payment infrastructure, the new entity creates a formidable, all-in-one solution that competitors may struggle to match.

The move strengthens One Call's leadership position and puts pressure on other players in the workers' compensation managed care space, such as MedRisk and Healthesystems, who may now face a competitor with a more deeply integrated and efficient operational backbone. The creation of a purpose-built, bilateral network for data and payments could set a new standard for the industry, compelling others to either build similar capabilities or seek partnerships to remain competitive.

This consolidation aims to address systemic industry challenges, including rising medical cost inflation and the increasing complexity of claims. By leveraging technology to automate administrative tasks and provide clearer data insights, integrated platforms like the one One Call is building can help manage costs and improve the overall efficiency of the workers' compensation system.

Integrating Leadership and Technology for Future Growth

To ensure the strategic vision is realized, the deal includes a critical leadership transition. Bryan Doyle, who served as President and CEO of Data Dimensions, will move into the role of Chief Business Officer at One Call. This move is crucial for embedding Data Dimensions' deep institutional knowledge and technological expertise within One Call's executive team, facilitating a smoother integration of both technology and company culture.

In his statement, Doyle expressed enthusiasm for the new chapter. “TSCP has been a valuable partner in helping us accelerate innovation, invest in our technology platform and expand our reach," he said. "We are grateful for the partnership and excited to begin our next chapter with One Call.” His transition to a key leadership role signals a commitment to leveraging the full potential of the combined assets.

Doyle's appointment is part of a broader trend at One Call of bringing in experienced executives to bolster its strategic capabilities. The company's focus on building a robust leadership team underscores its commitment to not only acquiring technology but also integrating the talent and vision required to deploy it effectively. As the two companies begin the complex work of merging their platforms, the market will be watching closely to see how this powerful new combination transforms the delivery of care for injured workers across the nation.
