Range Overview
high priority
The ICD-10 code range E08-E13, Diabetes mellitus, is used to classify and document various types of diabetes, including Type 1, Type 2, gestational, and drug-induced diabetes. It also covers complications and manifestations associated with diabetes, such as diabetic retinopathy, nephropathy, neuropathy, and others. The codes in this range are essential for accurate medical billing and epidemiological studies, and they help in tracking the prevalence and treatment outcomes of diabetes.
Key Usage Points:
- •Always specify the type of diabetes (Type 1, Type 2, gestational, etc.) when coding.
- •Use additional codes to identify any insulin use.
- •For patients with Type 2 diabetes who routinely use insulin, code Z79.4, 'Long-term (current) use of insulin', should be assigned.
- •When coding for diabetic complications, use combination codes that identify both the type of diabetes and the complication.
- •Uncontrolled diabetes does not have a specific code in ICD-10. Instead, it should be coded as the type of diabetes with hyperglycemia.
Coding Guidelines
When to Use:
- ✓When a patient is diagnosed with any type of diabetes.
- ✓When a patient with diabetes presents with complications such as retinopathy or nephropathy.
- ✓When a patient's diabetes is described as uncontrolled or out of control.
- ✓When a patient with diabetes is admitted for an unrelated condition, but their diabetes affects their treatment.
When NOT to Use:
- ✗When a patient has prediabetes or impaired glucose tolerance, these conditions have their own codes (R73.0 and R73.01).
- ✗When a patient has secondary diabetes caused by another condition, such as Cushing's disease or pancreatic disease.
- ✗When a patient's diabetes is well-controlled and does not affect their treatment for other conditions.
- ✗When a patient has a history of gestational diabetes but is not currently pregnant.
Code Exclusions
Always verify exclusions by checking the patient's full medical history and the specific circumstances of their diabetes.
Documentation Requirements
To accurately code for diabetes, the documentation must clearly specify the type of diabetes, any associated complications, and the control status of the diabetes. The documentation should also include any insulin use, and the relationship between diabetes and any other conditions the patient has.
Clinical Information:
- •Type of diabetes (Type 1, Type 2, gestational, etc.)
- •Control status of diabetes (controlled, uncontrolled, or out of control)
- •Any complications or manifestations associated with diabetes
- •Any insulin use
- •The relationship between diabetes and any other conditions the patient has
Supporting Evidence:
- •Lab results showing blood glucose levels
- •Medical history showing previous diagnoses or treatments for diabetes
- •Notes from physical examinations or patient interviews
- •Any relevant imaging or pathology reports
Good Documentation Example:
Patient diagnosed with Type 2 diabetes, currently uncontrolled with hyperglycemia. Regularly uses insulin. Also has diabetic retinopathy.
Poor Documentation Example:
Patient has diabetes.
Common Documentation Errors:
- ⚠Not specifying the type of diabetes
- ⚠Not documenting the control status of the diabetes
- ⚠Not documenting any associated complications
- ⚠Not documenting the relationship between diabetes and other conditions

Complexity Rating
Coding for diabetes can be complex due to the need to accurately identify the type of diabetes, any associated complications, and the control status of the diabetes. Additionally, the coder must consider any insulin use and the relationship between diabetes and any other conditions the patient has. However, with careful review of the documentation, these factors can be accurately coded.
Key Factors:
- ▸Determining the type of diabetes
- ▸Identifying and coding for any complications
- ▸Determining the control status of the diabetes
- ▸Coding for insulin use
- ▸Identifying the relationship between diabetes and other conditions
Specialty Focus
The E08-E13 code range is used across many specialties, but is particularly important in endocrinology, primary care, and obstetrics for gestational diabetes. These codes are also used in ophthalmology, nephrology, and neurology for the complications of diabetes.
Primary Specialties:

Clinical Scenarios:
- • A patient with Type 1 diabetes presents with diabetic retinopathy.
- • A patient with Type 2 diabetes is admitted for a foot ulcer.
- • A pregnant patient is diagnosed with gestational diabetes.
- • A patient with diabetes presents with kidney disease.
- • A patient's diabetes is described as uncontrolled.

Frequently Asked Questions
How do I code for uncontrolled diabetes?
Uncontrolled diabetes should be coded as the type of diabetes with hyperglycemia. There is no specific code for uncontrolled diabetes in ICD-10.
Do I need to code for insulin use?
Yes, if a patient with diabetes is routinely using insulin, code Z79.4, 'Long-term (current) use of insulin', should be assigned.
