I would wait for the letter from the VA. I had a similar thing happen and even though the rater asked the examiner to opine on something that I did not claim to include whether it was as least as likely as not caused by, etc.., it was not mentioned in my letter. The examiner was even asked and she did opine that it was caused by and as least as likely greater than 50% etc..
I am filing another claim for it.
Not sure were the rater was going with the questions, but it was on a reffered part of the claim.
