Thanks for your response Edge. I e-mailed the question to the Treasury HSA info address and this was their reply:
If you pay an overdraft fee from the account, any later repayment through the account is a contribution, that will be an excess contribution if the person has already contributed the maximum. So the immediate withdrawal would need to be coded as a withdrawal of an excess contribution. The overdraft fee itself is not a normal administration fee, so it cannot be treated as a medical expense, but if it is in fact an excess contribution, that won't matter.
So, I'm still on the fence. It would appear to be a headache, especially when I don't foresee these accounts being overdrawn too often. If we coded the withdrawal of the fee incorrectly, it could cause worse headaches than its worth. (If I'm interpreting the reply correctly.)
Any other thoughts?
