About Rx Group Purchasing:

Overview and History of Rx Group Purchasing

Towers Watson launched the first Rx Group Purchasing arrangement in 2004 in partnership with legacy Medco Health Solutions. This original offering, named the Rx Collaborative, was established to transform the business model and management processes for pharmacy benefit programs, and reestablish employers' control over cost, quality and effective delivery of their pharmacy benefit plans.

In June 2012, Rx Group Purchasing announced a new partnership with CVS Caremark as an additional PBM partner. This second partnership broadens our offerings and provides options from two major PBM vendors.

Rx Group Purchasing includes the following offers:

  • Rx Collaborative
  • Rx CVS Caremark Collaborative

Today, Towers Watson Rx Group Purchasing arrangements represent over 170 clients with combined annual drug spend of over $3.2 billion.


Mission Statement

The Rx Group Purchasing model is designed to take dollars out of the system and put employers back in the driver's seat.

Rx Group Purchasing Founding Mission
Transform the business model and management processes for pharmacy benefit programs to reestablish employer control over cost, quality and delivery effectiveness.

Rx Group Purchasing Rationale
Prescription drug costs have grown significantly over the past five years. Moreover, since actual manufacturing costs, discounts and other aspects of drug pricing are largely invisible to employers, it is extremely difficult for them to effectively manage their drug benefit programs. By banding together and building from a clear picture of actual costs, employers and PBMs can more effectively collaborate on utilization management, disease management, formulary development and other key initiatives. These overall efforts will have a sustainable long-term impact on overall costs and quality.

Rx Group Purchasing Scale
As of January 1, 2012, Towers Watson Rx Group Purchasing arrangements include over 170 participating employers with combined annual drug spend of over $3.2 billion. Our employers represent a diverse range of industries and include companies of all sizes.

Rx Group Purchasing PBMs
Legacy Medco Health Solutions (MHS) was selected as the first PBM for this initiative. In 2003, before selecting MHS, Towers Watson evaluated 17 PBMs as part of a comprehensive assessment process. In 2010, an RFP was sent to 25 organizations, and six bids were evaluated. Again, legacy Medco Health Solutions was the successful bidder. Towers Watson continues to conduct periodic market assessments in order to negotiate the most competitive contract. In 2012, during a time of PBM-industry consolidation, Rx Group Purchasing was expanded to include a second partnership with CVS Caremark.
