If you have questions about our billing process or if you would like to pay your bill online, you’ve come to the right place.

Our promise is to provide accurate and affordable testing for all patients. We support all patients—with or without insurance—by offering interest-free payment plans and patient assistance programs to all who qualify. Our dedicated Patient Advocacy team is here to handle all of your billing inquiries.

Insurance Claim

After your testing is complete, we will submit a claim to your health insurance plan, whether we are in or out of network. We’ll work directly with your insurer to make sure you get the appropriate coverage.

Explanation of Benefits

Your health insurance plan will then send you an Explanation of Benefits (EOB). The EOB is not a bill; it is simply an explanation of charges. Do not make any payments based on your EOB.


After our claim is processed, you may receive an invoice from Pathnostics for any remaining patient responsibility. The claims process may take months to complete, so don’t worry if you don’t receive an invoice right away.

Patient Rights and Protections Against Surprise Medical Bills

When you get emergency care or get treated by an out-of-network provider at an in-network hospital or ambulatory surgical center, you are protected from surprise billing or balance billing. Learn more about the No Surprises Act. Please feel free to contact our Patient Advocacy team with any questions or concerns you may have about your bill.
