Laboratory Services, NHP - 2019 UnitedHealthcare Administrative Guide

Direct all NHP members to LabCorp, Inc. service centers for outpatient laboratory (lab) procedures. If a participating care provider draws the specimen in the office, send the specimen to LabCorp, Inc.

Home healthcare agencies are responsible for "drop off" of drawn specimens at one of the LabCorp, Inc. service centers.

We pay lab services according to your agreement. They must be performed by a participating care provider that is a facility for:

  • Emergency room services;
  • Chemotherapy;
  • Ambulatory surgery;
  • Transfusions; or
  • Hemodialysis.

LabCorp, Inc. must process clinical laboratory specimens drawn at a skilled nursing facility.

Use of Non-Participating Laboratory Services

This applies to all participating care providers. It also applies to laboratory services, clinical and anatomic, ordered by any practitioner.

You are required to refer laboratory services to participating laboratories, except as otherwise authorized by NHP. To get more information on participating laboratories:
