Have you noticed how the ophthalmic community seems to talk in code? PT w/? IOP f/u VF OU. And sometimes we even make-up our own abbreviations system.
I once audited Evaluation and Management (E&M) chart notes and found that the technician would frequently use “BE.” I was confused as to what this could possibly mean. Then it was explained to me, BE = both eyes. It was a few days later that I also learned that BE in the medical world actually stands for barium enema!

To avoid confusion or even embarrassing mistakes, here are some of the most commonly used appropriate abbreviations. Use them to standardize documentation in the medical record.
When you are audited, the nurse reviewer will know exactly what you are referencing. And you might consider submitting this list along with your chart notes for easier interpretation.
