ICD-10 Code E11.622 – Type 2 diabetes mellitus with other skin ulcer (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E11.622 – Type 2 diabetes mellitus with other skin ulcer
What it is
E11.622 identifies type 2 diabetes mellitus complicated by a skin ulcer that is not classified as a diabetic foot ulcer. Use it when the record links the ulcer to diabetes and specifies another skin site.
Clinical signs
Typical documentation includes a chronic open skin wound, delayed healing, or ulceration in a non-foot location. Clinical features vary; refer to documentation for the ulcer site, depth, and any stated diabetic association.
When to use this code
Use this code when the provider documents type 2 diabetes with an ulcer of the skin and clearly connects the two conditions. It is appropriate for ulcers on areas such as the leg, arm, or trunk when the site is not described as a foot ulcer. If the note does not specify the relationship or location, check documentation.
Do not use for
Do not use E11.622 for diabetic foot ulcers, which are coded elsewhere. Do not assign it when the ulcer is unrelated to diabetes or when the record only says “skin ulcer” without a diabetic link.
Coding tip
Confirm both the diabetes type and the ulcer location in the provider note before assigning E11.622.
