Surveyor thinks I miscoded section E

We're having our annual survey. Surveyor is questioning me on why I coded a lady on anxiousness about health issues and insomnia (I coded less than daily on these 2 items).

On the lady's first couple of days at our facility, she confided in the social worker a few times how worried she was that she can get back to prior level of function after her bilateral knee replacement. The social worker charted about this in her notes. However, the nurses notes said nothing about any anxiousness. The MAR showed 2 entries where she was given PRN Ambien for insomnia. The insomnia didn't appear anywhere in narrative form in the nurses notes either, though.

I explained to the surveyor that I observed her anxiousness and so did the social worker the first few days. The surveyor replied "well, I'd be anxious, too--wouldn't anybody?" I then told the surveyor that we had to code things we see on section E regardless of the reason. She again stated she could'nt understand why I coded anxiousness and insomnia when it didn't appear in the chart (..."just that little blurb in the social service notes".."and maybe the MAR", in her words)

Now I'm questioning myself for coding these things... Do you all think this is worthy of a deficency?
