ICD-10 Code E09.10 – Drug or chemical induced diabetes mellitus with ketoacidosis without coma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E09.10 – Drug or chemical induced diabetes mellitus with ketoacidosis without coma
What it is
This code identifies diabetes caused by a drug or chemical, complicated by diabetic ketoacidosis, but without coma. Use it when the documentation links the diabetes and ketoacidosis to an external substance.
Clinical signs
Typical findings include hyperglycemia with ketones and acidosis, along with dehydration, nausea, vomiting, abdominal pain, or rapid breathing. Clinical features vary; refer to documentation.
When to use this code
Use E09.10 when the provider documents drug- or chemical-induced diabetes mellitus and specifically states ketoacidosis without coma. It fits cases where the substance cause is identified, such as medication-related diabetes. If the record does not clearly connect the condition to a drug or chemical, check documentation.
Do not use for
Do not use this code for ordinary diabetes mellitus with ketoacidosis, or for ketoacidosis without documented drug or chemical causation. Do not assign it if coma is present.
Coding tip
Verify both the causative substance and the absence of coma in the provider note before coding.
