Billing Information

Billing Information

Currently, we bill a referring provider’s institution directly for all clinical testing. Typically, an invoice will be sent to the ordering institution on the month following a patient’s sample being processed and reported. The institution can expect a cumulative invoice of all patients whose samples were processed during the previous month. The invoice will be sent to the e-mail provided on the Customer Onboarding Form.

We currently do not provide direct-to-payer billing services. Please contact us if you have any questions.
