The use of standardized coding systems and, more generally, of medical terminologies allow to guarantee semantic interoperability during the exchange of clinical information between different healthcare information systems.

The coding systems indicated by the Technical Regulation attached to the DPCM on the EHR and used to encode information present in the clinical documents indexed and exchanged within regional EHR systems are listed as follows. For each system, information about national and international contacts, versions indicated by the DPCM and the last updates are given.
