Have you come across a form of diabetes with an unusual presentation or a rare underlying cause? Luckily, the ICD-10 codes for diabetes cover every manifestation of the disease imaginable in very specific terms. In this article, I’ll go through the full range of diabetes ICD-10 codes and provide some guidelines for how to use them appropriately in your medical records.
What Are the ICD-10 Codes for Diabetes?
These lists cover all of the ICD-10 codes for diabetes mellitus.
You can use the following links to navigate to the codes you need depending on which type of diabetes you’re looking for:
- Diabetes due to underlying conditions (codes that start with E08)
- Drug or chemical induced diabetes (codes that start with E09)
- Type 1 diabetes (codes that start with E10)
- Type 2 diabetes (codes that start with E11)
- Diabetes related to pregnancy (codes that start with 024)
- Other types of diabetes not covered by the previous categories (codes that start with E13)
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.

ICD-9 to ICD-10 Codes for Diabetes Conversion Table
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”).

Guidelines on Using ICD-10 Codes for Diabetes
As many ICD-10 codes as necessary can be used together to describe the patient’s form of diabetes. Pregnant women who are diabetic should be assigned a code from the 024 category first, followed by the appropriate diabetes codes in the E08 to E13 range. For gestational diabetes (diabetes that occurs during pregnancy) women should be assigned a code under the 024.4 subheading and not any other codes under the 024 category.
If the type of diabetes that the patient has is not documented in the medical record, E11 codes for type 2 diabetes should be used as a default. If the medical record doesn’t say what type of diabetes the patient has but indicates that the patient uses insulin, the Type 2 diabetes codes should also be used. The code for long-term use of insulin, Z79.4, should also be used in these cases (unless insulin was just given to the patient as a one-time fix to bring blood sugar under control).
Note that the word “with” in the code titles always means “associated with” or “due to” (it doesn’t refer to two disparate conditions). 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.

What Are ICD-10 Codes?
ICD (International Classification of Diseases) codes are a way for doctors to record diagnoses in a succinct universal language. ICD-10 codes refer to the codes from the 10th Revision of the classification system. ICD-10 officially replaced ICD-9 in the US in October of 2015.
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.
