Summary

Complex Extension: Phân bổ thành tiền bệnh viện của một dòng Claim vào bốn nguồn thanh toán trên bảng kê chi phí KCB: quỹ BHYT, người bệnh cùng chi trả, nguồn khác và người bệnh tự trả. Mỗi khoản bắt buộc có giá trị không âm và tiền tệ VND. Dòng chi tiết bên trong gói thiết bị được biểu diễn bằng Claim.item.detail và không mang extension này; phân bổ chỉ bắt buộc ở item tổng gói. Căn cứ: [QĐ 697/QĐ-BYT] (ban hành 19/03/2026, hiệu lực 19/03/2026) — Mẫu bảng kê chi phí KCB. This extension allocates a Claim line's hospital amount across the four payment sources in the itemized healthcare-cost statement: the BHYT fund, patient co-payment, other sources, and patient self-pay. Every component is required, non-negative, and denominated in VND. Device-package detail rows are represented by Claim.item.detail and do not carry this extension; allocation is required only on the package-level item.

• insuranceFund: Money: Số tiền của dòng do quỹ BHYT thanh toán, tương ứng cột 10. The line amount paid by the BHYT fund, corresponding to column 10.
• patientCopay: Money: Số tiền người bệnh cùng chi trả trong phạm vi BHYT, tương ứng cột 11. The patient's co-payment within BHYT coverage, corresponding to column 11.
• otherSource: Money: Số tiền của dòng do nguồn khác thanh toán, tương ứng cột 12. The line amount paid by other sources, corresponding to column 12.
• patientSelfPay: Money: Số tiền người bệnh tự trả ngoài phần cùng chi trả BHYT, tương ứng cột 13. The patient's self-pay amount outside BHYT co-payment, corresponding to column 13.
