What ICD-10 Codes are Used for Diabetes Type 2?

There are multiple Diabetes Type 2 ICD codes you can use when coding or billing. Here’s a list of some of them:

E11.0: Type 2 diabetes mellitus with hyperosmolarity.

Hyperosmolarity is a condition wherein a high concentration of substances like sodium, glucose, etc., is located in the blood that draws water out of other organs like the heart and brain.

E11.1: Type 2 diabetes mellitus with ketoacidosis

Ketoacidosis is a condition wherein the liver produces ketones too quickly, causing a build-up in the blood, consequently making the blood acidic.

E11.2: Type 2 diabetes mellitus with kidney complications

Under this code, three kidney complications are mentioned: diabetic nephropathy, diabetic chronic kidney disease, and other diabetic kidney complication.

E11.3: Type 2 diabetes mellitus with ophthalmic complications

Under this code, some complications are nonproliferative diabetic retinopathy, proliferative diabetic retinopathy, diabetic cataract, and diabetic macular edema, resolved following treatment.

E11.4: Type 2 diabetes mellitus with neurological complications

Under this code, complications mentioned are: diabetic neuropathy, unspecified; diabetic mononeuropathy; diabetic polyneuropathy; diabetic autonomic (poly)neuropathy; diabetic amyotrophy, and diabetic neurological complication

E11.5: Type 2 diabetes mellitus with circulatory complications

Under this code, there are three circulatory complications, namely: diabetic peripheral angiopathy without gangrene, diabetic peripheral angiopathy with gangrene, and other circulatory complications

E11.6: Type 2 diabetes mellitus with other specified complications

Among the other specified complications are skin complications, oral complications, hypoglycemia, hyperglycemia, etc.

E11.8: Type 2 diabetes mellitus with unspecified complications
E11.9: Type 2 diabetes mellitus without complications

Note that codes E11.0 to E11.6 has more codes under them for specificity. One should check and utilize the more specific codes, valid and billable until the end of fiscal year 2023.

Which Diabetes Type 2 ICD codes are Billable?

E11.8, E11.9, and most specific codes under codes E11.0, E11.1, E11.2, E11.4, and E11.5 are billable. However, numerous specific codes under E11.3 and E11.6 are not billable.

Clinical Information

More commonly known as diabetes, diabetes mellitus has several types.
Type 2 diabetes, which is the most common type of diabetes, differs from the other types because of two things: the pancreas cannot produce enough insulin to keep blood sugar levels within a healthy range, and cells in the muscle, fat, and liver are insulin resistant.
It takes a while for the symptoms of this diabetes type to develop; hence one may be unable to detect the condition until it worsens. However, the symptoms one may experience as the condition progresses are increased thirst, unexplained weight loss, fatigue, slow healing of cuts/sores, and frequent urination/skin infections.
People who are at high risk of developing type 2 diabetes are those with a family history of type 2 diabetes, have low levels of “good” cholesterol, are overweight, have uneven fat distribution, lack physical activity, and those diagnosed with polycystic ovary syndrome.
Diagnosis involves the patient undergoing a blood test. The practitioner in charge then checks their blood sugar over some time.
There is no treatment for diabetes; instead, patients have to manage their blood sugar by monitoring it, taking medication/insulin, and choosing to live a healthy lifestyle.

Synonyms Include:

Hyperglycemia due to diabetes mellitus
Diabetic ketoacidosis
Disorder of kidney due to diabetes mellitus
Cataract due to diabetes mellitus
Disorder of nervous system due to diabetes mellitus
Peripheral circulatory disorder due to type 2 diabetes mellitus

Commonly asked questions

You can use any of the codes after you confirm the diabetes type and determine any possible complications with tests.

Most of the diabetes type 2 codes are billable. It is recommended, however, that you double-check if the code you will use is billable. For more information, refer to the “Which Diabetes Type 2 ICD codes are Billable” section above.

Rather than cure, treatments are provided to manage one’s condition. Some of them are to monitor one’s blood sugar, take medications/insulin, and live a healthier lifestyle.
