In looking at SNOMED codes included in Value Sets, the listed SNOMED codes do not seem to pull in all more granular codes that have a IS A relationship to those included. While there will certainly be exceptions (depression value set excluding "in remission" codes may be intended, etc) and errors in the SNOMED hierarchy, every value set I've looked at seems to be missing codes that would work.
Attached is one example set based on the glaucoma value set. The SNOMED codes in column D & E have a IS A relationship to SNOMED codes used in the value set (columns B & C).
Unfortunately, I'm not currently familiar with the value set editors, but is there a planned improvement to the SNOMED explosion logic?
