Pharmacogenomics Testing

Our mission is to serve as a trusted partner to physicians, healthcare professionals and patients by providing quality testing services. Pharmacogenomics is being implemented into routine clinical practice as the medical and pharmaceutical industries move from a one-size-fits-all model to a personalized medicine approach. PGX testing can improve medication management by reducing trial and error prescribing, minimizing adverse drug reactions, improving medication compliance and quality of life, and managing health costs.

Testing Process

Our testing process is quick and easy. Once a licensed provider orders the test, the sample can be collected in the provider’s office. The Test Report is available within 7-10 days.


  • Non-invasive cheek swab that can be collected in the provider’s office
  • Easy access to reports through our secure online portal
  • Capable of integrating with electronic health record systems, in partnership with MedTek21

Billing Policy

Genemarkers is committed to providing physicians and patients with quality service, which includes ensuring patients have a clear understanding of the billing process and establishing a manageable payment arrangement.

  • Claim Submission

    Once your test results are sent to your physician, our billing department bills your insurance company for our services using industry-compliant billing practices.

  • Claim Review

    After your insurance company reviews the information (this may take up to 30-90 days), your insurance company will send you an explanation of benefits (EOB) detailing the allowable charges for the services and how much will be covered based on your policy coverage. The EOB is NOT a bill.

  • Claim Appeal

    Genemarkers will appeal appropriate cases as necessary. This process varies by insurance company and you will receive a second EOB.

  • Claim Assistance

    You may receive a bill from Genemarkers for your co-pay or deductible amount. If you have any questions about your bill or cannot pay your bill, please contact our billing department by phone at 844-220-6231. We work around a patient’s financial ability to pay and will work directly with each patient to settle their account, including setting up payment plans. In the case of financial hardship Genemarkers offers special pricing. Please contact us to receive the hardship waiver.

Genemarkers EOB Example

If you are a patient with Medicare:

A completed ABN is required. The ABN explains the test and possible patient responsibility.

If you are a patient with Group or Individual Insurance:

Co-pays, co-insurance, and deductibles may apply. Balances billed to the patient will be determined by the patient’s insurance plan. A payment arrangement may be negotiated for individuals with financial hardship.

Any questions?

Please contact us at 844-220-6231.
