ICD-10 Code E10.622 – Type 1 diabetes mellitus with other skin ulcer (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E10.622 – Type 1 diabetes mellitus with other skin ulcer
What it is
This code identifies type 1 diabetes mellitus complicated by a skin ulcer that is not classified elsewhere. Use it when the record links the ulcer to the patient’s type 1 diabetes.
Clinical signs
Clinical features vary; refer to documentation. You may see a chronic open skin lesion, delayed healing, or surrounding tissue breakdown in a patient with type 1 diabetes.
When to use this code
Use E10.622 when the provider documents type 1 diabetes and an associated skin ulcer, and no more specific ulcer code applies. The ulcer should be described as diabetic-related or clearly linked to the diabetes. Check the note for location and any additional ulcer detail.
Do not use for
Do not use this code for ulcers without documented diabetes linkage, or for type 2 diabetes. If the ulcer is better classified by another diabetic complication code, use that more specific code instead.
Coding tip
Pair E10.622 with the most specific ulcer site and severity documentation available.
