Billing Information

Thank you for choosing Exosome Diagnostics to perform your prostate cancer risk assessment. Through our laboratory services, we seek to empower patients with information to help them make informed decisions about their care. Similarly, we want to empower patients with information related to the costs of the test and our billing policy so that you can minimize concerns regarding payment. We are here for you at every stage of the billing process.

Claim Filing

We file your claim. →

Exosome Diagnostics will file a claim with your insurance company once The EPI Test is processed. Insurance typcially responds in less than two months with a coverage decision.*

Coverage Decision

We manage the process →

Exosome Diagnostics will work on your behalf to ensure you get the best coverage benefit.  When applicable, Exosome Diagnostics will appeal the denial with your insurance.  The insurance company will review the appeal to make a coverage or denial determination.

During this time, you may receive several Explanation of Benefits (EOB) statements. **

This is not a bill


You receive a statement

After the claims process is complete, or when the appeals process has reached a decision***, you will receive a statement for any outstanding cost-sharing amounts (for example, co-payment, co-insurance, deductibles) that remain your responsibility.

* If the claim is processed by insurance, most patient statements will be sent within 60 days from the date of service. If the claim has undergone the appeal process, it may take 6 months or longer to receive a patient statement outlining the patient responsibility. This statement will be followed by a bill for any amounts owed to Exosome Diagnostics, which must be paid within 30 days.

** An EOB is provided to you as a summary of your medical expenses and how claims were processed by your insurance company. An EOB will outline any cost-sharing amounts (co-insurance, deductible, or patient balance) that are the patient’s responsibility. THIS IS NOT A BILL.

*** Even after a coverage decision has been made by a patient’s insurance company, the patient may be eligible to pay a reduced cost if they qualify for our Patient Assistance Program (PAP). For more information on the PAP, please see reverse side.

The EPI Test is cutting-edge technology

This test will help you gain greater confidence and peace of mind to make a decision with your urologist or other healthcare providers about whether to proceed with a biopsy or not.

Patient Assistance Program

The cost of the test may be reduced for patients who qualify for our Patient Assistance Program (PAP), which evaluates eligibility for discounted out-of-pocket rates based on household income levels.

The PAP is only available to patients in the United States and US territories. To qualify, patients must complete and submit a PAP application form with proof of household income directly to our billing department.

Frequently Asked Questions

Is the EPI Test covered by health insurance?

Most claims are covered by insurance companies and we continue to add coverage from additional insurance plans. However,only your insurance company can determine if the cost of the test is a covered benefit. The code to use is CPT PLA 0005U.


If I have health insurance, will I have any out-of-pocket expense?

Please review the information on our Patient Assistance Program (PAP) to determine whether you qualify for a reduced out-of-pocket cost for The EPI Test.
