Controlled vocabularies are by definition "controlled" - adding, modifying or deleting terms from within a controlled vocabulary is done expressly by a curator.

Indeed, it's common for such vocabularies to have not one but many "other" terms:  after "hepatitis A", "hepatitis B", etc. it is usual to have "hepatitis, not otherwise specified".  Indeed this is common enough to have the standard abbreviation "NOS".
