Hi, I wanted some insight on if my team's approach on CodeSystem and ValueSet are correct. Use CodeSystem called "file-cateogries". Then use ValueSet to create two "versions": admin and staff - admin has access to all codes but staff does not have access to some. Further on, we plan to use CodeSystems to categorize our patient visits (initial, checkup, followup) . Is this the correct use of CodeSystem and ValueSet? Thank you very much!
