I would talk to your Quack and see if what she had has a name. If it does, check that company's list to see if it's on there.
My experience is that some conditions carry no weighting (IE they will be noted on the policy when you declare them but you don't get charged extra).
But beware....some companies will outright refuse to cover some conditions. A company I asked for a quote from said they would not cover any medical fees incurred from a fall. And there were several other things they refused to cover. I mean, what is the point? Even if you are perfectly fit, you want this sort of cover in the event of something unexpected like a fall....
But I have always been totally honest with these quotes, declaring every minor thing. Otherwise, if you make a claim and they find out you haven't declared something (even if it's totally irrelephant to the claim), they can refuse cover.
