ICD-10 Code E09.620 – Drug or chemical induced diabetes mellitus with diabetic dermatitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E09.620 – Drug or chemical induced diabetes mellitus with diabetic dermatitis
What it is
This code identifies diabetes caused by a drug or chemical, with diabetic dermatitis present. Use it when the record links the skin condition to diabetes secondary to a medication or chemical exposure.
Clinical signs
Clinical features vary; refer to documentation. Diabetic dermatitis is typically documented as a skin manifestation in a patient with diabetes, often described as dry, scaly, or pruritic lesions.
When to use this code
Use E09.620 when the provider documents drug- or chemical-induced diabetes and specifically notes diabetic dermatitis. The chart should support both the secondary diabetes cause and the skin manifestation. If the cause is not stated, check documentation before coding.
Do not use for
Do not use this code for type 1, type 2, or gestational diabetes. Do not use it when dermatitis is unrelated to diabetes or when the diabetes cause is not drug or chemical induced.
Coding tip
Verify the causal agent and the manifestation are both documented before assigning E09.620.
