Function: get277Status()

get277Status(delimiters, tx): X12ClaimStatusResponse | undefined

Extract a typed X12ClaimStatusResponse from a 277 / 277CA transaction set. Pure function - no I/O, no global state. Returns undefined only when ST-01 is not "277" (mis-routed call); every other deviation is recoverable and surfaces on result.warnings. The transactionType discriminator is derived from ST-03 (005010X214 → "claim-acknowledgment", otherwise "claim-status").

Parameters​

delimiters​

Delimiters

tx​

X12TransactionSet

Returns​

X12ClaimStatusResponse | undefined

Example​

import { parseX12, get277Status } from "@cosyte/x12";
const ix = parseX12(raw);
for (const group of ix.groups) {
  for (const tx of group.transactions) {
    if (tx.st.elements[1] !== "277") continue;
    const status = get277Status(ix.delimiters, tx);
    for (const claim of status?.claims ?? []) {
      claim.traces[0]?.referenceId;                 // echoed 276 trace
      claim.statuses[0]?.statuses[0]?.statusCode;   // "20"
    }
  }
}
