OK, not really. I didn't even know the origin of that term until I started teaching. But the common usage implies looking for small things wrong (hmm, making a mountain out of a mole hill?)
But I had been annoyed by a local medical clinic. I didn't get a bill, but all of a sudden I'd have a notice from a collection agency. I'm not the only one it happened to because I heard people complaining in the staff room at school. I couldn't figure out how it was happening.
Then last week I actually read one of those insurance papers. It denied coverage for something it would normally pay because the claim wasn't filed in a timely manner (nine months later, in fact). So I went to the clinic and asked about it. She said if it is their fault, they write it off. I said that I thought they should but what they actually do is send it to a collection agency next.
She gave me a phone number and said to call the ones who do their billing. So I did and have put a copy of the letter from the insurance company in the mail. This would explain a lot. The woman in billing said she had not gotten a copy of that and for me to send her one.
The medical care at that facility was fine, but the bookkeeping wasn't.
