Claim status transaction (276/277)
The claim status transaction — X12 276 inquiry and 277 response — lets a provider ask a payer where a submitted claim stands without waiting for the remittance.
Updated
The claim status transaction is the HIPAA-standard electronic exchange for tracking a claim: a provider sends an X12 276 inquiry asking the status of a claim it has already submitted, and the payer returns an X12 277 response reporting where the claim is in its process — received, in adjudication, paid, denied, or rejected, for example.
It is distinct from the remittance advice, which reports the payer's payment decision and the financial detail; the 276/277 reports status only and can be queried before the remittance arrives, making it a follow-up tool rather than a payment record.
In practice
The 276/277 is how a practice finds out whether a payer has a claim it has not yet paid and whether the silence means in-progress, denied, or never received. Because it carries no money, reading it has to be a scheduled step — like acknowledgments — otherwise claims that are quietly pending or rejected age past their filing window before anyone looks.
Commonly confused with
- Eligibility transaction (270/271): The 270/271 verifies coverage before a service; the 276/277 asks the status of a claim after submission. They answer different questions at different points in the cycle.
- Claim acknowledgment (999/277CA): A 999/277CA is the payer's unsolicited acknowledgment that a transmission arrived and which claims it accepted; the 276/277 is a provider-initiated status query about a claim already in process.
- Remittance advice: The remittance reports the payment decision and the financial adjustment; the 276/277 reports status only, with no money or adjustment detail.
