Billing Information

billing information

Our goal at Exosome Diagnostics, Inc. (Exosome) is to provide you information on the reimbursement process that will occur between you and your insurance company and provide you the best possible coverage for the EPI test ordered by your healthcare provider.


Our billing process is outlined below: 

Step 1

Claims Submission

Exosome will file a claim to your insurance company for payment once the EPI test your physician ordered has been processed. The typical time for an insurance company to respond to a claim is approximately 45 days.

Step 2

Review of Explanation of Benefits (EOB)

Once your plan has processed the claim for the EPI test, they will send you a statement called an Explanation of Benefits (EOB). The EOB is NOT A BILL, but is provided to you and to Exosome as a summary of how your insurance company processed the claim. An EOB also shows any cost sharing amounts (co-insurance, deductible, or patient balance) that are your responsibility. 

Step 3


If coverage is denied, Exosome will promptly appeal the claim on your behalf. After the appeal is reviewed, your insurance company will make a coverage or denial payment determination. You may receive multiple EOBs during this process, which is standard practice. As a reminder, the EOB is not a bill and does not require any action on your part.

Step 4

Patient Statement

Upon completion of claims processing with your insurance company, Exosome may send you a patient statement for any outstanding cost sharing amount; co-payments, co-insurance, or deductibles. Most patient statements will be sent upon 90 days from the date of service unless the claim has been appealed, in which case, those statements may not be sent for up to 6 months. This statement will be followed by a bill for any amounts owed to Exosome, which must be paid within 30 days.
