ICD-10 Code E13.10 – Other specified diabetes mellitus with ketoacidosis without coma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.10 – Other specified diabetes mellitus with ketoacidosis without coma
What it is
This code identifies ketoacidosis occurring in a form of diabetes that is not type 1 or type 2, and the patient is not in coma. Use it when the record clearly specifies “other specified diabetes mellitus” with ketoacidosis.
Clinical signs
Clinical features vary; refer to documentation. Typical ketoacidosis findings may include dehydration, nausea, vomiting, abdominal pain, and altered breathing patterns, but the record should confirm the diabetic type and absence of coma.
When to use this code
Use E13.10 when the provider documents ketoacidosis linked to other specified diabetes mellitus and explicitly states there is no coma. It fits cases where the diabetes type is described as another specified form, such as secondary diabetes, and the encounter centers on ketoacidosis. Check documentation if the diabetes type is unclear.
Do not use for
Do not use this code for diabetic ketoacidosis with coma, or when the record documents type 1 or type 2 diabetes instead. If the diabetes category is not specified, check documentation before coding.
Coding tip
Verify both elements in the note: the specific diabetes category and the absence of coma.
