For the person

In Every Patient

At Prometheus, we understand that every patient is a person with individual needs. Our approach is to help people and their doctors learn more about the nature of their condition in order to obtain an accurate diagnosis, providing the right drug, for the right patient.

Learning more about the conditions that affect your health is important so that you can take a more active role in decisions regarding your care. If you have any questions or would like to reach out for more information, please contact us.

Insurance and Billing

Prometheus was founded to develop and provide diagnostic testing services for patients suffering with GI & autoimmune diseases. With a primary focus on the diagnosis, prognosis and monitoring of gastrointestinal and inflammatory diseases and disorders, our goal is to deliver products that help enable clinicians to optimize care and make a meaningful difference in their patients’ lives. Prometheus offers a variety of specialty testing that may not be available at your regular laboratory facility. We recommend checking with your own insurance company about reimbursement and the need for a prior authorization before having your specimen collected. Prometheus may have agreements with laboratories in your area, which may help lower your out-of-pocket expenses. If your physician does not direct you to a specific laboratory for testing, contact Client Services for assistance.

  • Prometheus is a Medicare participating provider.
  • As a courtesy, Prometheus will bill your primary insurance carrier (complete information must be provided), but we cannot predict the level of reimbursement.
  • Prometheus may bill you for any unpaid balance due to deductibles, co-payments, co-insurance and non-covered services.


Payment for services is due upon receipt of an invoice from Prometheus. We accept payment by check, money order, and most major credit cards. To ensure that your payment is processed correctly please include the patient name and patient reference ticket number(s) / ID number with your payment. Credit card payments can be processed by phone. Payment by mail should be sent to:

If you feel that your insurance company should pay some or all of your bill, but your statement indicates that no claim was filed, please contact our billing department immediately with the information necessary to file a claim. If a claim was appropriately filed and you feel that your insurance company should pay some or all of the balance due, please contact your insurance company to resolve this as soon as possible. Once testing services have been initiated and/or results have been provided, all sales are final.
