ICD-10 Code E09.5 – Drug or Chemical Induced Diabetes Mellitus with Circulatory Complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E09.5 – Drug or chemical induced diabetes mellitus with circulatory complications
What it is
This code identifies diabetes caused by a drug or chemical, with documented circulatory complications. Use it when the record links the diabetes to an external substance and notes vascular involvement.
Clinical signs
Clinical features vary; refer to documentation. You may see evidence of peripheral or other circulatory disease in a patient whose diabetes is attributed to medication or chemical exposure.
When to use this code
Use E09.5 when the provider states that a drug or chemical caused the diabetes and also documents a circulatory complication. Code the condition only when both elements are clearly supported in the record. If the cause or complication is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for ordinary diabetes mellitus without a drug or chemical cause. It is also incorrect if the chart does not support a circulatory complication or if the diabetes type is unspecified.
Coding tip
Look for explicit provider linkage between the substance exposure, diabetes, and the circulatory complication before coding E09.5.
