ICD-10 Code E11.9 – Type 2 diabetes mellitus without complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E11.9 – Type 2 diabetes mellitus without complications
What it is
E11.9 identifies type 2 diabetes mellitus when the record does not document a specific complication. Use it for diabetes without noted kidney, eye, nerve, circulatory, or other listed complications.
Clinical signs
Clinical features vary; refer to documentation. Type 2 diabetes is commonly identified by abnormal glucose testing, a prior diabetes diagnosis, or ongoing charted diabetes management without documented complications.
When to use this code
Use E11.9 when the clinician documents type 2 diabetes and no complication is mentioned in the note. It is also appropriate when the record supports diabetes, but the available documentation does not specify a related condition. If a complication is documented, code that condition instead.
Do not use for
Do not use E11.9 when the chart documents diabetic complications such as kidney disease, neuropathy, retinopathy, or a foot ulcer. Do not use it for type 1 diabetes, gestational diabetes, or unspecified diabetes.
Coding tip
Check the full encounter note for linked diabetes complications before assigning E11.9.
