ICD-10 Code E09.59 – Drug or chemical induced diabetes mellitus with other circulatory complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E09.59 – Drug or chemical induced diabetes mellitus with other circulatory complications
What it is
This code identifies diabetes caused by a drug or chemical exposure, with circulatory complications that are not otherwise specified. Use it when the record links the diabetes to the offending substance and notes a related vascular problem.
Clinical signs
Clinical features vary; refer to documentation. You may see diabetes with evidence of circulatory involvement, such as vascular insufficiency or other blood-flow complications, documented alongside the drug- or chemical-induced cause.
When to use this code
Use E09.59 when the provider documents diabetes due to a medication, toxin, or other chemical and also specifies a circulatory complication. The record should clearly connect both the diabetes and the vascular issue to the same condition. If the circulatory complication is not stated, check documentation.
Do not use for
Do not use this code for diabetes from other causes, such as type 1, type 2, or gestational diabetes. Also avoid it when the chart does not document a circulatory complication or does not identify the drug or chemical cause.
Coding tip
Verify the causal agent and the specific circulatory complication in the provider note before assigning E09.59.
