ICD-10 Code E11.10 – Type 2 diabetes mellitus with ketoacidosis without coma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E11.10 – Type 2 diabetes mellitus with ketoacidosis without coma
What it is
This code identifies type 2 diabetes mellitus complicated by ketoacidosis, but the patient is not in coma. Use it when the record clearly documents diabetic ketoacidosis linked to type 2 diabetes.
Clinical signs
Typical findings include hyperglycemia with ketone production and symptoms such as nausea, vomiting, abdominal pain, dehydration, or altered breathing. Clinical features vary; refer to documentation.
When to use this code
Use E11.10 when the provider documents type 2 diabetes with ketoacidosis and specifically states there is no coma. It fits encounters for acute management, follow-up after stabilization, or problem lists when the condition remains active. If coma is documented, select the more specific code.
Do not use for
Do not use this code for type 1 diabetes, diabetic ketoacidosis with coma, or ketosis without documented ketoacidosis. Check documentation if the diabetes type or presence of coma is unclear.
Coding tip
Confirm both the diabetes type and the absence of coma in the provider note before assigning E11.10.
