Company Billing Customer Service Phone Number: 1-866-697-8378 (1-866-MYQUEST)

This company offers a large range of test / testing products and services that benefit patients, healthcare providers, and pharmaceutical medical device companies, life insurance companies and employers.

If you are a patient, you may have received an invoice.  Even though you may not have physically visited a Quest Diagnostics location, your physician may have sent your specimen out to a one of their laboratories to be tested so the invoice you received is for laboratory services that were ordered by your physician. Generally, this invoice is for laboratory testing fees only and is separate from any bill you may have received from your physician and/or paid at your physicians office.

Please find the message printed on your specific invoice or the Explanation of Benefits (EOB) from your insurance carrier for more specific information about why you have received an invoice.

Here are a few more reasons you may have received an invoice:

  • Your insurance information was not received or the wrong insurance information was received on your test order.
  • Your insurance carrier processed the claim and denied payment and will not pay the invoice.
  • Your insurance carrier processed the claim and applied the balance to your co-pay or deductible instead of paying the invoice.
  • Your insurance carrier did not respond to the claim.

NOTE: please visit the site directly to verify the details and obtain more information.
