Health Care Claim Status Request transactions enable healthcare providers, billing agents, or other authorized entities to inquire about the status of previously submitted insurance claims. Typically sent by a provider or clearinghouse to a health plan or claims processor, this transaction set allows requesters to track pending claims and obtain payment information. The ST (Transaction Set Header) segment identifies the message type and control number, while the BHT (Beginning of Hierarchical Transaction) segment provides timestamps and purpose codes for the inquiry. The HL (Hierarchical Level) segment, which appears in the mandatory Loop 2000, establishes the hierarchical relationships between entities involved—such as subscriber, provider, or claim information—enabling the sender to specify exactly which claims or claim-related details require status verification.

A practical example illustrates this workflow: Community Health Partners submits a 276 request to Blue Cross Insurance to check the payment status of a claim initially submitted for patient Jane Smith. The request includes Smith’s subscriber identification through the SBR (Subscriber Information) and DMG (Demographic Information) segments, along with claim reference numbers in the TRN (Trace) segment within Loop 2200. By including specific service line details in the optional Loop 2210 SVC (Service Information) segment—such as procedure codes and dates of service—Community Health Partners can request status on individual line items rather than the entire claim. Blue Cross receives the 276, processes the inquiry against its claims database, and responds with a corresponding 277 transaction that provides current claim status, claim amounts, and payment details.
