Fine.
But beware of exceptions. That comes from my domain expertise
in software development. The client billing system that I maintain
has such exceptions. I sometimes have had to redo parts of it
because a change broke the paradigm that I was using.
And you create another problem. Have you ever seen a fast DE
person at work? A dropdown would slow them down
considerably. The problem was someone not checking what was
entered. The answer is not to slow everyone down. That does not
cause the checking to get done.
Incremental search in a combobox speeds things up quite a bit. Plus,
medical billing is not rote work. It requires thought throughout the
process. IMO, a slight loss of speed can be amply compensated by a
significantly reduced risk of error. Different people here will
argue about where the greatest
The loss of speed might not be slight for the data entry person.

of the process. The taxpayer pays for all segments though, not just one. YMMV.
Putting speed ahead of accuracy is foolish, but hobbling
everyone is similarly foolish. When I am entering transactions in an
accounting system, I like a batch system, because I can print the
batch and check it thoroughly against the input documents before I
post the batch. Not everyone does this, and if data entry is made
slower, it is likely that even fewer will do so, because of the extra time.
