I don't know about your pathologists, but ours read out "multilayered epithelium", an entity that no one yet knows what to do with, and MAY be a pre-cursor to Barrett's. There is no ICD9, and as far as I know, no ICD10 for this condition either.
But, if this becomes something in the future, it might be nice to have a handy way to quickly pull up all your patients with this condition. This sort of searching/reporting is easy to do with entities that have a ICD code, like Crohn's. You just search for the ICD's (from the problem lists) and voila.
Recently, I figured out that I could just make up an ICD code if one didn't exist, so I created one for Multilayered Epithelium. So that I would never be in conflict with a REAL code, I gave it the ICD9 code of "MLE."
Now, any time i see someone with multilayered epithelium, I can enter this in their problem list, and I'll be able to search for these folks easily in the future.
I don' t know what others "diagnosis" don't yet have a code, but this is a handy trick to know about...
Fortunately, gMED does not restrict us to just #### ICD's, so feel free to use words/letters, like I did.
