With regards to #26 "Ability to hide/delete actual worded diagnosis when using ICD-9 code" this can already be done. As long as the diagnosis starts with a number sign and ends with the the ICD code in parenthesis followed by a colon, you can change the wording to anything you want.

For example, I recently changed

Quote
# MIGRAINE WITH AURA WITHOUT MENTION OF INTRACTABLE MIGRAINE WITHOUT MENTION OF STATUS MIGRAINOSUS (346.00):

to

Quote
# Classic Migraine (346.00):

Or does #26 refer to something else?
