Odd validation of concept id

This is totally fine. Here is a whole discussion In short: The concept was active during some time in the past. Now it can’t be used because of some billing issues or something. But it reflected some clinical data anyway. So, if we don’t have equivalent of this concept, we still keep it standard to be able to represent its meaning.
