Returns

X12ServicesReview | undefined

import { parseX12, get278Request } from "@cosyte/x12";
const ix = parseX12(raw);
const tx = ix.groups[0]?.transactions.find((t) => t.st.elements[1] === "278");
if (tx !== undefined) {
  const req = get278Request(ix.delimiters, tx);
  req?.reviews[0]?.requestCategoryCode; // "HS"
  req?.reviews[0]?.diagnoses[0]?.code;  // "E1165"
