I have encountered an issue with several LOINC part codes which are not included in recent LOINC release files, yet they are still listed as “Active” when searched using the static URL format.  
Examples of such LOINC part codes include:  
[https://loinc.org/LP128659-2](https://loinc.org/LP128659-2)  
[https://loinc.org/LP263703-3](https://loinc.org/LP263703-3)

Have these codes been retired? Are the URLs not up-to-date with latest LOINC releases?

Thanks.

Hello Ali, thank you for bringing this to our attention. We are investigating now. In the interim, you can consider the content in the LOINC release files as accurate. It appears the issue is with the mechanism used to display these Part details pages.

Thanks for the confirmation. The same issue occurs with list and answer codes as well.
