seems, NO.
but who knows actually, for example we discovered this in HCPCS which has never happened before,
see here: HCPCS codes change their meaning over time
if vaccine is not in use anymore, they keep the code.
see here: IIS | Code Sets | CVX | Vaccines | CDC
Yes, it will.
But I checked the concepts from my initial example and they aren’t linked to ATC currently.
