General Billing Policy

Commercial Insurance
GeneDx requires a written letter of pre-authorization in order to bill insurance for these tests. This letter should state that the request for genetic testing for the specific disease/gene has been approved. It is most helpful if the level of reimbursement is also included in the letter. In most cases, an authorization number alone will not be acceptable. GeneDx will then courtesy bill the insurance. Please be sure to send us complete insurance information, and include a copy of the front and back of the insurance card. A patient will be responsible for all fees not covered by insurance. Credit card information is required at the time of sample submission for billing the outstanding balance
Institutional bill
GeneDx can bill a referring institution directly if an Institutional Account with GeneDx has been established. This allows the referring physician to submit samples through their facility’s send out laboratory. Establishment of an institutional account is very simple and requires the laboratory administrator to contact our billing department by either call at 301-519-2100, x 6106 or email at
GeneDx requires a credit card at the time of sample submission. If patient is paying by money order or check, minimum of 75% of the cost of the test is required at the time of sample submission, with the remainder of the fee billed at the time of test completion. For patients from outside the United States, 100% of the fee is due at the time of sample submission.
GeneDx is currently not a Medicare provider and therefore not able to accept Medicare patient samples.
GeneDx is currently not a Medicaid provider and therefore not able to accept Medicaid patient samples.
International bill
Samples from outside the United States must be accompanied by full payment at the time of sample submission. This can be accomplished by wire transfer, check, or credit card. To obtain information for wire transfer, please contact GeneDx by e-mail ( or phone, 301-519-2100.
