GPO Membership Benefits

We are your Smart GPO.

What does it mean to be a Smart GPO? For us, it means using data and actionable insights to support your practice in the transition to value-based care. It means providing analytics tools to help you align with national guidelines. And it means using empirical evidence to put patient outcomes at the heart of your practice's health and sustainability.

When you join AmerisourceBergen Specialty GPOs, you become part of a network of community oncology practices making data-backed decisions to advance the quality of patient care. That's having a smart partner in your corner.

GPO Contracting

When it comes to group purchasing, there's strength in numbers. As the largest and longest-standing oncology-specific GPO, we represent nearly two-thirds of independent community oncology practices. That means we have unrivaled collective purchasing power in the industry. Our relationships with leading manufacturers translate into a versatile contract portfolio, with diverse, physician-vetted discount and rebate models that are not only valuable, but attainable. Learn more about how we partner with practices to ensure you get the most from your contracts.

Bringing reliable partners to the table

Pharmaceutical partners

We partner with the country’s leading pharmaceutical and biotech manufacturers to give you access to a full range of products that deliver value for your practice. Additionally, members get access to timely clinical education and manufacturer-sponsored solutions—like medication therapy management and patient assistance programs—that enhance clinical outcomes. It's just one more way we're working hard for you, every day.

Partner solutions and services

We know that it takes more than smart contracting to run a successful community oncology practice. That's why we connect our members with service partners who can help you deliver care more efficiently, unlock financial opportunities, and enhance the quality of your patient care. By offering the most advanced diagnostic tools, genetic testing and supplemental care at exclusive pricing, we provide more opportunities for you to keep your practice moving forward.

Where reach equals results

The foundational premise of a GPO is that we are more effective when we work together. As part of the AmerisourceBergen family of companies, we deliver on that promise by advocating for your practice from every angle.
