Missing Payments & Underpayments: Remittance Advices and Your Pharmacy

Do you know when you can expect payment from third party payors for prescription claims? According to a Net-Rx study of 2,187 NCPDP’s over a 6-month period, 86.1% of claims are paid within 15 to 30 days after the promise to pay was issued (Peterkin, 2021). Whether the funds are received by paper check or electronically deposited into the pharmacy’s bank account, they are usually delivered along with an explanation about the payment. This can come in many formats, such as Remittance Advices (RA), Electronic Remittance Advices (ERA), Explanation of Benefits (EOB), Explanation of Payments (EOP), Electronic Data Interchanges (EDI), 835 Files, or 5010 Files (Stuhlmeyer, 2020).

But the complexity does not end there, each third-party payer can have different formats and details such as, claim types and adjustment codes.  With all this complexity, remittance advices can quickly become extremely challenging to decipher. It is not surprising that pharmacies can sometimes fail to identify underpayments, or worse, miss non-payments of a bulk of claims in their entirety!   

The remittance advice is an explanation of the payment , and outlines payment details such as check number, check date, check amount, the specific prescription(s) included in the payment, and details of any adjustments made to an individual claim or the final payment amount. Depending on how many prescriptions are included in a payment, remittance advices could potentially contain hundreds or thousands of lines of details .

It is important for pharmacies to review the corresponding remittance advice for each payment and reconcile with the claim adjudicated within their dispensing software. Only, through this reconciliation process, can pharmacies identify missing payments or short payments  and if needed, follow up with the third-party payers to determine when payment can be expected. Often, the remittance advice will include adjustment codes describing the reason behind the short payment or adjustment. However, the coding used is not universal across all third-party payers and can be vague or misleading. 

The picture below is an example of what an electronic remittance advice may look like. Imagine trying to decipher this to find unpaid claims!

Remittance advices can be complicated and directly impact a pharmacy’s ability to successfully reconcile claims . Consistently tracking adjudicated claims, reimbursements, and incoming payments, knowing how to identify missing payments, short payments, and adjustments, and who to reach out to for clarification is a great start to optimal reimbursement. Technology can also be leveraged, as there are many software solutions specific to pharmacy reconciliation available. Utilizing technology is quicker, easier, and reliable.  A robust reconciliation solution can provide a clear picture of claims and payment data along with intuitive reporting allowing for improved management of pharmacy reimbursement and a deeper understanding of your pharmacy’s financial status.

Now, isn’t a report like this much easier to decipher?
