Additionally, in the near future, the structure of 835 files delivered to MedRx clients will change. Since February 21, 2024, MedRx 835 files have been delivered as one file per check. With this upcoming change, 835 files will be delivered in batches by payer with each batch potentially containing multiple checks. This change is intended to improve processing efficiency for both MedRx and client systems. We will send an update once this change is in place.

Please contact our pharmacy helpdesk at 866-379-6389 or your client executive for any questions on either change.
