Used to request the status of a previously submitted insurance claim, the 925 transaction set enables healthcare providers, billing services, and other claim originators to inquire about claim processing with payers and intermediaries. The transaction begins with an ST (Transaction Set Header) segment, which establishes the message structure and control information. Each claim inquiry is organized within an F10 Loop that contains the F10 (Identification of Claim) segment—the core element specifying which claim is being traced—along with an optional F02 (Identification of Shipment) segment for additional shipment or submission context. The transaction concludes with an SE (Transaction Set Trailer) segment. The repeating F10 Loop structure allows multiple claim status inquiries to be submitted in a single transmission, enabling efficient batch processing of tracer requests.

For example, Community Health Billing Services prepares a daily batch of claim status inquiries and sends it to United Healthcare as an X12 925 transaction. Within the transmission, multiple F10 Loops reference specific claims submitted weeks earlier—one for patient John Doe’s emergency room visit claim (referenced in the F10 segment by claim number and date), another for a surgical procedure claim, and a third for outpatient diagnostics. Each loop includes optional F02 information if the claims were submitted as part of a larger shipment batch. United Healthcare receives the 925 transmission, matches each traced claim to its internal records, and prepares a corresponding 997 Functional Acknowledgment or claim status response, allowing Community Health to follow up on delayed or missing claim adjudications.
