Preferred Lab Network

The following labs will continue to be a part of the Preferred Lab Network. The Preferred Lab Network consists of currently contracted independent, freestanding laboratory care providers. These laboratory care providers have met higher standards for member access, cost, data, quality and service, based on a rigorous application and review process.

Referring patients to these labs may help reduce their out-of-pocket costs for services, as well as lab testing costs for their employer groups. This applies to UnitedHealthcare commercial plans, UnitedHealthcare Community Plans and UnitedHealthcare® Medicare Advantage plans.

Preferred Lab Network

The Preferred Lab Network features currently contracted independent, free-standing laboratory care providers that have met higher standards for access, cost, data, quality and service. We will work with these distinguished labs to continue our efforts to improve the care provider and member experience.

There is no change in lab access for members or care providers. Members can still use a lab in UnitedHealthcare’s extensive network of over 300 labs, even if that lab isn’t in the Preferred Lab Network. However, choosing a lab in the Preferred Lab Network may let the member schedule patient service center appointments online and may lead to shorter wait times for services, higher quality of care and lower cost.

Requesting services from labs in the Preferred Lab Network

We expect physicians who refer to labs in the PLN to notice prompt turn-around times for lab results, ease-of-use when ordering labs electronically as well as easy access to physician-to-lab medical director consultations to support patient care. They will not need to do anything different to access services from these providers. Preferred Lab Network labs will be labeled in our care provider directories.

Preferred Lab Network labs will perform covered tests. However, available services may vary by lab. The lab’s Preferred Lab Network directory listing will include the type of testing available. The lab’s website will also list the type of tests performed and their locations.
