If you are using Version 184.108.40.206 or newer, you might have noticed something different with your diagnosis codes. Some codes are in uppercase and some codes are in lowercase. Why, you ask? The answer is ICD-10s are the codes in lower case and ICD-9s are the codes in upper case. You now have access to both. Choose which code you want to use. Show your physician the code he would previously have used and what the new code is in ICD-10!
