ICD-10 Codes – Type 1 Diabetes Mellitus

Diabetes means your blood glucose or blood sugar is too high. With type 1 diabetes, your pancreas does not make insulin. Insulin is a hormone that helps glucose get into your cells to give them energy. Without insulin, too much glucose stays in your blood. Over time, high blood glucose can lead to serious problems with your heart, eyes, kidneys, nerves, and gums and teeth. Type 1 diabetes happens most often in children and young adults but can appear at any age.

Guidelines for 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.

E10 Type 1 Diabetes Mellitus

ICD Code E10 is a code. To code a diagnosis of this type, you must use one of the eight child codes of E10 that describes the diagnosis ‘type 1 diabetes mellitus’ in more detail.

E10.2 Type 1 diabetes mellitus with kidney complications

    • E10.21 Type 1 diabetes mellitus with diabetic nephropathy
    • E10.22 Type 1 diabetes mellitus with diabetic chronic kidney disease
    • E10.29 Type 1 diabetes mellitus with other diabetic kidney complication

E10.3 Type 1 diabetes mellitus with ophthalmic complications

    • E10.33 Type 1 diabetes mellitus with moderate nonproliferative diabetic retinopathy
    • E10.34 Type 1 diabetes mellitus with severe nonproliferative diabetic retinopathy
    • E10.35 Type 1 diabetes mellitus with proliferative diabetic retinopathy
    • E10.36 Type 1 diabetes mellitus with diabetic cataract
    • E10.39 Type 1 diabetes mellitus with other diabetic ophthalmic complication

E10.4 Type 1 diabetes mellitus with neurological complications

    • E10.40 Type 1 diabetes mellitus with diabetic neuropathy, unspecified
    • E10.41 Type 1 diabetes mellitus with diabetic mononeuropathy
    • E10.42 Type 1 diabetes mellitus with diabetic polyneuropathy
    • E10.43 Type 1 diabetes mellitus with diabetic autonomic (poly)neuropathy
    • E10.44 Type 1 diabetes mellitus with diabetic amyotrophy
    • E10.49 Type 1 diabetes mellitus with other diabetic neurological complication

E10.5 Type 1 diabetes mellitus with circulatory complications

    • E10.51 Type 1 diabetes mellitus with diabetic peripheral angiopathy without gangrene
    • E10.52 Type 1 diabetes mellitus with diabetic peripheral angiopathy with gangrene
    • E10.59 Type 1 diabetes mellitus with other circulatory complications

E10.6 Type 1 diabetes mellitus with other specified complications

    • E10.61 Type 1 diabetes mellitus with diabetic arthropathy
    • E10.62 Type 1 diabetes mellitus with skin complications
    • E10.63 Type 1 diabetes mellitus with oral complications
    • E10.64 Type 1 diabetes mellitus with hypoglycemia

    • E10.69 Type 1 diabetes mellitus with other specified complication

E10.8 Type 1 diabetes mellitus with unspecified complications

E10.9 Type 1 diabetes mellitus without complications

Hyperosmolar Hyperglycemic State (HHS)

Hyperosmolar hyperglycemic state (HHS) is a complication of diabetes mellitus (predominantly type 2) in which high blood sugars cause severe dehydration, increases in osmolarity (relative concentration of solute) and a high risk of complications, coma, and death. It is diagnosed with blood tests. It is related to diabetic ketoacidosis (DKA), another complication of diabetes more often (but not exclusively) encountered in people with type 1 diabetes; they are differentiated with measurement of ketone bodies, organic molecules that are the underlying driver for DKA but are usually not detectable in HHS.
