I would say its a standard question, as some people may be upgrading or still serving waiting times.
Did they confirm if you are covered or not?
As a matter of interest, what two plans are involved?
I would think its a routine initial question, but it should be quickly followed with reassurance as to what you're covered for regarding
levels of hospital cover etc. Once you have health insurance continuous for 5 years, you are covered for pre-existing conditions and
new conditions ( assuming you were under 55yrs when you joined.) As regards level of hospital cover, it would depend on the plan you are on.
