Onmark Group Purchasing Organization (GPO) Services

Trusted expertise, superior specialty drug savings.

We’re entering a new era of care delivery, and with it comes the challenge of managing the costs of exciting new therapies for a growing patient demand. While any GPO can offer you discounts, the Onmark GPO has the proven expertise and track record you can trust to help your practice maximize the full economics available on your drug purchases.


How the Onmark GPO model works for you

Onmark’s primary focus is getting our members the best pricing possible on their drug purchases. While our members also have access to McKesson Specialty Health tools and services such as inventory management and in-office dispensing, we believe a GPO should focus on getting your specialty practice the best possible price on your drug purchases.

With the Onmark approach, our members have access to:

  • A best-in-class contract portfolio
  • Savings on top therapeutic options in oncology, rheumatology, gastroenterology, retina, urology, neurology and other advanced specialties, including oral and self-admin products
  • A proven team of experts who help you achieve additional, performance-based savings tools to track your performance

Drug pricing that aligns with advances in medicine

The Onmark GPO stays ahead of new trends in medicine and works continually with manufacturers to deliver new contracts or expand savings on existing contracts. Our approach often allows us to offer GPO pricing at the time of product launch, as well as additional, performance-based savings opportunities for top specialty products.

Specialty practice services tailored to you: the McKesson difference

Providing the best contract portfolio means working closely with our members to understand their needs and provide beneficial drug savings. Whether you’re an existing or potential customer, contact a McKesson Specialty Health representative today and see what the Onmark GPO can do for your practice.
