ICD-10 Code E09.622 – Drug or Chemical Induced Diabetes Mellitus with Other Skin Ulcer (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E09.622 – Drug or chemical induced diabetes mellitus with other skin ulcer
What it is
This code identifies diabetes caused by a drug or chemical, with a skin ulcer that is not classified elsewhere. Use it when the record links the ulcer to this diabetes condition.
Clinical signs
Clinical features vary; refer to documentation. You may see signs of diabetes plus a documented skin ulcer, often with impaired healing and tissue breakdown.
When to use this code
Use E09.622 when the provider documents drug- or chemical-induced diabetes mellitus and also specifies an associated skin ulcer. The ulcer site and laterality should be documented, and you should code any additional details as instructed in the record.
Choose this code only when the diabetes is clearly medication- or chemical-related, not when diabetes type is unspecified. If the ulcer is not documented as linked to the diabetes, check documentation.
Do not use for
Do not use this code for diabetic ulcers due to type 1 or type 2 diabetes, or for skin ulcers without a documented diabetes link. Check documentation.
Coding tip
Verify both the cause of diabetes and the ulcer relationship before assigning E09.622.
