With the release of 2.83 I’m still seeing a large volume of LOINC codes that are not discouraged in the Drug/Tox class that have a method of either Screen or Confirm. Should these have been discouraged as well? An example would be

| [40802-1](https://loinc.org/40802-1) | Cocaine [Presence] in Saliva (oral fluid) by Screen method |
| --- | --- |

Hello Jeremy! Thank you for asking! We didn’t complete the Drug/Tox project in one release. There are just over 300 terms to be built; and the committee hasn’t made suggestions yet on Drug/Tox panels. We will work with HDS staff to assure the discouraged status gets updated in the future.
