What is the Billing Process at Gnosis?

Here’s how the billing process typically works at Gnosis:

  1. Service Provision: You undergo laboratory testing or services prescribed by your healthcare provider at Gnosis.
  2. Claim Submission: Gnosis submits a claim to your insurance provider for the services rendered. This claim includes details such as the type of test performed, associated charges, and relevant diagnostic codes.
  3. Insurance Processing: Your insurance provider reviews the claim and determines coverage according to your policy. This may include factors such as deductibles, co-pays, and coverage limitations.
  4. Explanation of Benefits (EOB): After processing the claim, your insurance provider sends you an Explanation of Benefits (EOB). The EOB outlines how the claim was processed, including what portion of the cost was covered by insurance and any patient responsibility, such as co-pays or deductibles.
  5. Patient Billing: If there are any out-of-pocket expenses not covered by insurance, such as deductibles, co-pays, or services not covered by your plan, you will receive a bill from Gnosis. This bill will detail the services provided, the amount covered by insurance, and any remaining balance due from you.
  6. Payment: You are responsible for paying any remaining balance indicated on your bill. This can typically be done through various payment methods accepted by Gnosis, such as credit card, check, or online payment portal.

If you have any questions or concerns about your laboratory bill, including insurance coverage, billing statements, or payment options, please don’t hesitate to contact our billing department at Gnosis. We’re here to assist you and ensure that you have a clear understanding of your financial responsibilities related to your healthcare services.

Why did I receive an EOB from my health insurance carrier for services rendered by Mountain View Medical Laboratory and not Gnosis?

You might have received an Explanation of Benefits (EOB) from your health insurance carrier for services rendered by Mountain View Medical Laboratory rather than Gnosis because Gnosis operates under the umbrella of Mountain View Medical Laboratory. While still providing the excellent care you’re accustomed to from Mountain View, Gnosis offers an enhanced range of services and cutting-edge expertise. So, although the billing might come from Mountain View, rest assured that you’re receiving the same quality of care with the added benefits of Gnosis’s expanded services and innovation.
