To correct issues introduced in Version 2.79 and add terms accidentally omitted, a Hotfix labeled Version 2.80 was released in February 2025.
All users who have implemented Version 2.79 into their systems are encouraged to upgrade to Version 2.80 as soon as possible. If you have not yet incorporated Version 2.79, you may skip to Version 2.80 without issue. Similarly, RELMA Version 7.13 contains content from LOINC 2.80 which supersedes RELMA 7.12 and LOINC 2.79.
With over 3,000 new and edited concepts, these enhancements ensure improved data standardization, interoperability, and regulatory compliance, supporting the broader goals of healthcare modernization and quality improvement.
