The switch to ICD-10 was a response to the need for doctors to record more specific and accurate diagnoses based on the most recent advancements in medicine. For this reason, there are five times more ICD-10 codes than there were ICD-9 codes. The ICD-10 codes consist of three to seven characters that may contain both letters and numbers.
The “unspecified” codes can be used when not enough information is known to give a more specific diagnosis; in that case, “unspecified” is technically more accurate than a more specific but as yet unconfirmed diagnosis. For more guidelines on using ICD-10 codes for diabetes mellitus, you can consult this document.
The more characters in the code, the more specific the diagnosis, so when writing a code on a medical record you should give the longest code possible while retaining accuracy.
Here's a conversion table that translates the old ICD-9 codes for diabetes to ICD-10 codes. There weren’t as many codes to describe different conditions in the ICD-9, so you’ll notice that some of them have more than one possible corresponding ICD-10 code. Some are also translated into a combination of two ICD-10 codes (note the use of the word "and").
