Thanks, @DTorok. This is a bug. Looks like SNOMED deprecated it and replaced it with - itself. That’s how it must have snuck through. Let’s find out.

Forget what I said. Mixed up the two concepts (both ending in 62)

The replacement can be “Concept replaced by” or “Concept is possibly equivalent to”. That’s SNOMED notation. They either distinctly replace something, or they invalidate a concept and give us more of a probabilistic replacement.

So, all good.
