Billing FAQ

Why have I received a bill when I have insurance to cover my laboratory testing?

There are a few reasons this may have happened:

  • Insurance information was not received with the test order
  • Insurance information was incorrect or could not be confirmed with the carrier
  • The insurance carrier processed the claim and denied payment
  • The insurance carrier processed the claim and applied the balance to your co-pay or deductible

Please refer to the explanation of benefits (EOB) from your insurance carrier for more specific information. If you have additional questions or concerns about your coverage, please contact your insurance carrier directly. If you have updated/corrected insurance information, please send the correct insurance information to us by faxing a copy of the invoice and copy (front and back) of your insurance card to 972.630.6411 or mail to:

I received a check from my insurance company, can I cash the check?

In some instances, one of Gulfstream Diagnostics' labs will file as an out of network provider with your insurer. The carrier may send payment directly to you instead of us. If you receive payment for our laboratory services, please contact us to arrange payment or remit payment to us by writing the lab on the back of the check,

  • "Payable to Laboratory Services of East Texas" or
  • "Payable to East Texas Referral and Testing" then sign and mail the check and copy of the EOB to:

Gulfstream Diagnostics, LLC
Attn: Billing - Insurance Reimbursement

Can Gulfstream Diagnostics tell me how much I can expect to pay for my tests?

The price you pay for tests performed by East Texas Referral and Testing or Laboratory Services of East Texas will depend on several variables, such as:

  • If you have insurance or not
  • Your insurance plan coverage of laboratory tests
  • Eligibility for financial assistance

Why did my doctor test me?

It is recommended that physicians nationwide implement and maintain a comprehensive, therapeutic drug-monitoring program. To achieve this, your physician will ask for a sample to accurately identify the drugs within your system. This ultimately provides a more complete treatment program for you.

I received an invoice requesting additional information. What should I do?

Please send the requested information to the address or fax number listed on your invoice. You can also call the Customer Service phone number listed on your invoice. If the message on your invoice indicates that your insurance carrier needs more information from you in order to process your claim, please contact your insurance carrier directly.

What can I do when my claim is denied due to the diagnosis code?

Diagnoses are provided by the ordering physician's office. If your claim was denied due to the diagnosis code, please contact your physician's office.

My claim was denied for coordination of benefits. What do I need to do?

Your insurance carrier has identified you as having more than one insurance carrier and the insurance provided to us is not the primary payer. Please send a copy of your primary insurance card (front and back) to Gulfstream Diagnostics by fax to 972.630.6411 (Attention: Billing Department) or by mail to:

Gulfstream Diagnostics, LLC
Attn: Billing Department
9301 N. Central Expressway

If you do not have other coverage, please contact your insurance carrier to update their records.
