ICD-10 Code E13.620 – Other specified diabetes mellitus with diabetic dermatitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.620 – Other specified diabetes mellitus with diabetic dermatitis
What it is
This code identifies diabetes mellitus in the “other specified” category when diabetic dermatitis is documented. Use it when the record links the skin condition to diabetes and no more specific diabetes type applies.
Clinical signs
Clinical features vary; refer to documentation. Diabetic dermatitis typically refers to diabetic skin changes such as shin spots or other skin lesions described as related to diabetes.
When to use this code
Use E13.620 when the provider documents other specified diabetes mellitus with diabetic dermatitis, or clearly states a diabetic skin manifestation tied to this diabetes category. Code the condition only when the relationship is documented or implied by the record. Check documentation if the diabetes type is unclear.
Do not use for
Do not use this code for diabetes without a documented dermatitis manifestation, or for skin disease not linked to diabetes. If the chart supports a different diabetes category, use the more specific code instead.
Coding tip
Confirm both the diabetes category and the skin manifestation are documented before assigning E13.620.
