Summary

Simple Extension with the type Identifier: Mã lượt khám chữa bệnh (trường MA_LUOT_KCB per QĐ 3176/QĐ-BYT). Được mô hình hóa như Identifier để giữ nhất quán system / value / type khi đối soát BHXH. Khác với Encounter.identifier — MA_LUOT_KCB là mã nội bộ cho từng lượt khám và dùng NamingSystem khuyến nghị riêng.
