Description
Code list aiming to identify individuals consulting complaining of loss or change in taste and/or smell.
Methodology
Identified from intial search terms outside of OpenCodelists: "taste" "smell" "anosmia" "hyposmia" ageusia" "hypogeusia" "olfact" parageusia" "odour" "odor"
Clearly irrelevant codes excluded (with review by a second clinician)
Candidate codelist reviewed outside OpenCodelists by two clinicians. As we reviewed our candidate codelist outside openCodelists, we did not benefit from the tree structures that might have identified additional codes. However, we assume that these are likely to be codes that are not used frequently, e.g., eponymous syndromes.
Retained codes related to disordered taste/smell (as well as absent taste/smell) as there are reports of continuing change in taste/smell post COVID. Excluded all secondary taste/smell disorders, as indicate known cause. Retained codes relating to taste loss in anterior/posterior thirds of the tongue, as unclear yet whether taste loss post covid is related to neurological pathology.

Codelists are developed by a broad community of users for individual study purposes, which may or may not meet the needs of other studies. They should not be thought of as universal definitions of a particular condition.
We don't offer any guarantees about what they do or don't identify. Users should carefully check that any codelist meets their needs, and seek clinical input where appropriate.
