T/SHIA 018-2025 Coding Rules and Operational Requirements for Interoperable Projects in Medical Imaging
Basic Information
Scope
There are regional adaptive innovations in the coding rules: in the 15-digit code, the administrative division identifiers of "51(Sichuan)/50(Chongqing)" and exclusive price item codes (such as 51033 for DR examination in Sichuan) are set, and special identifiers for high-incidence diseases in Sichuan and Chongqing, such as Kashin-Beck disease and echinococcosis, are marked by the 9th digit code, which solves the problem of connecting national standards with local medical insurance policies. The coding structure reserves an extension bit to comply with the 16-bit field requirements of the DICOM protocol. The 11th and 12th digits identify the medical insurance version (such as the 2001 version of the National Standard and the 2022 version of Sichuan), and the 13th to 15th digits link to specific price items, providing support for the iteration of regional medical insurance versions.
