LabCorp will file claims directly to Medicare, Medicaid, and many insurance companies and managed care plans. Before you have lab tests performed, please make sure:

  • Your insurance information is up to date.
  • LabCorp is a contracted laboratory for your insurance company. Contact your insurance company for information.

Once your insurer has processed your claim, you will receive an Explanation of Benefits (EOB) from your insurer informing you of the amount it will pay for your laboratory services.

  • The EOB is not a bill, but it may indicate that a balance remains which is your responsibility. That balance may include your copayment, deductible, or other costs outlined in your terms of coverage. If you have a question about your EOB or your terms of coverage, contact your insurance company.
  • Your insurer will inform LabCorp about any balance you owe, and we will send you a bill for that amount.
