Ordering Information

The Steps

Questions about obtaining consent for genetic testing? Please reference our handout or reach out to one of our genetic counselors at ddl@jhmi.edu.

Please ship all samples to:

Johns Hopkins Genomics - DNA Diagnostic Lab
1812 Ashland Ave
Sample Intake; Room 245
Baltimore, MD 21205

  • The Johns Hopkins Genomics DNA Diagnostic Lab will now be utilizing an auto-activation or auto-cancellation policy for every sample we receive in the lab.

    When a sample is received in the lab, it will be evaluated to determine whether we have all necessary items needed to initiate testing.  If everything is in order, the lab will initiate testing for your patient as normal. 

    If items are missing upon sample arrival (e.g. test requisition form, consent, family member samples, billing documentation, etc.), this testing will be put on hold and you will be given 6 weeks before the testing is either auto-activated at the highest level of testing possible (applicable to exome duo, trio, or quad) or auto-canceled.  This 6-week date will be communicated to the provider upon sample arrival, along with a list of the items that are still pending.  If all necessary items are received before your auto-activation/cancellation date, testing will be initiated.  If items are still pending at the 4-week mark, the provider will be contacted again and reminded of the time remaining until an action will be taken on testing.   

    What is auto-activation?

    Auto-activation is only applicable for tests that require samples from more than one individual such as an exome duo, trio, or quad.  If your patient sample reaches the 6-week mark and there is enough documentation and samples to initiate some level of testing, the lab will do so.

    For example, if you ordered an exome trio and at the 6-week mark are only pending family member samples, the lab would initiate this testing as a proband-only exome.  This change will be communicated with the ordering provider.

    What is auto-cancellation?

    Auto-cancellation is applicable to all tests that require only a single patient sample.  If all necessary items needed to initiate testing are not received after 6 weeks of sample receipt, testing will be canceled.  If your testing is canceled, you will be notified by the lab and you will have 1 week to notify the lab if you need the sample returned to you before it is discarded. 

    *For external providers – if you request a sample to be returned please provide a FedEx account number to cover return shipping costs. The DNA Diagnostic Lab will not cover any shipping associated fees. 

    *For Hopkins providers – if the only item pending for your sample after 6 weeks is an insurance pre-authorization decision, this will remain on hold until it is either approved or denied.

    Please feel free to email us at ddl@jhmi.edu or call 410-955-0483 if you have any questions about this policy.  

  • Test Requisition Forms:

    Billing Forms:

    For additional information about out-of-pocket payment, Medicare and insurance billing, please see our billing information.

  • Samples require two (2) patient identifiers that match the sample with the accompanying paperwork. We are not able to test samples that are not properly identified.

    Accepted identifiers include:

    • Patient name and date of birth (preferred)
    • Internal identifiers (such as specimen ID or medical record number)

    Types of samples:

    • Blood Samples
    • Prenatal Samples
    • Saliva Samples
    • Other Samples
    • Unacceptable Samples
  • General Information

    • Johns Hopkins Genomics DNA Diagnostic Laboratory (JHG DDL) tests should be ordered through Epic. See our The EPIC order will require you to confirm the patient’s transfusion history and consent for testing. If you have not obtained consent for testing, use the reference links to complete the appropriate consent supplement. The consent supplements are included with the test instructions below.
    • See our Sample Requirements for additional guidance.
    • JHG DDL will pick up samples from the Clinic on Tuesdays and Fridays. If you have proband or parental saliva samples to be picked up, please place the samples in the “Johns Hopkins Genomics – Sample Pickup” box that will be placed in the GC suite. Samples from this box will be routinely picked up by a member of the JHG staff throughout the week.
    • If you need saliva kits, please email your request to ddl@jhmi.edu.
    • Have the sample taken to the Core Lab or have the patient report to Express Testing. Express Testing and the Core Lab will route the sample to the DDL.
    • If a sample is processed through the Core Lab, the Johns Hopkins Genomics DNA Diagnostic Laboratory is not involved in billing.
    • The prices provided on our web site apply to outside referrals and do not necessarily reflect what your patient will be charged. If a sample is drawn in 'regulated space', Maryland law regulates the fees charged for laboratory services based on CPT codes, relative value units (RVUs), and the current RVU reimbursement rate. Neither the Johns Hopkins Genomics DNA Diagnostic Laboratory nor the Department of Pathology control the assigned RVUs or RVU rates. Please contact Pathology Customer Service at 5-1921 to find out the current fee for a test.
    • If the patient is uninsured, has a non-contracted insurance plan, or will be paying out of pocket for any other reason:
      • Have the patient sample drawn in non-regulated space to minimize out-of-pocket expense (see draw sites below) and do not order the test in Epic or process the sample through the Core Lab or Department of Pathology.
      • Contact the Johns Hopkins Genomics DNA Diagnostic Laboratory for pricing information at 410-955-0483.
      • Include credit card information or a check made out to Johns Hopkins University.

    Billing

    The following requirements must be met in order to initiate testing:

    • Financial responsibility is established
    • Required forms are completed and received
    • Billing issues are resolved.

    We are not able to bill insurance plans with which we are not contracted to provide laboratory services, even if the plan authorizes testing.

    Note About CPT Codes - as many of our tests for rare diseases are using the unlisted code (81479), we anticipate an increase in denials of coverage. Verification of coverage of the test codes is required, and patients should be informed of the possibility of insurance denials.

    CPT Code List

    Billing options:

    Institutional Billing

    If the institutional billing option is selected, an invoice will be sent to the referrer’s organization and address unless otherwise specified in the billing section or on a separate sheet attached to the requisition form.
