When I edit the descriptor for an ICD-9 code, I leave the original, "real" descriptor there in parentheses, just in case. Maybe I'm over-cautious.
Speaking of cheat sheets, here is a link to the "Family Practice Management" magazine Short List, 600 of the most common codes for Family Practice. The sometimes-confusing "real" ICD-9 descriptors are replaced with informal, problem-oriented descriptors. The top 100 codes have a red arrow.

http://www.aafp.org/online/en/home/publications/journals/fpm/icd9.htmlYou will note there is also a Long List, with more four and five digit codes, which you might also find helpful.
The AAFP updates these every year.
The forms come in an Excel spreadsheet format also, and I guess they could be easily modified into a replacement ICD-9 database if somebody wanted to do that, or can our ICD-9 database be modified in that way?
