ICD-10 Code E08.622 – Diabetes mellitus due to underlying condition with other skin ulcer (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E08.622 – Diabetes mellitus due to underlying condition with other skin ulcer
What it is
This code identifies diabetes caused by another underlying condition, with a skin ulcer that is not specified as a foot ulcer. Use it when the record links the ulcer to the diabetic condition and the ulcer site is documented.
Clinical signs
Look for documented diabetes with a concurrent skin ulcer, such as an ulcer on the leg, ankle, or other skin area. Clinical features vary; refer to documentation for the underlying cause and ulcer location.
When to use this code
Use E08.622 when the provider documents diabetes due to another condition and an associated skin ulcer. The chart should support both the diabetes type and the ulcer site, with no indication that the ulcer is a diabetic foot ulcer instead.
If the underlying condition is not stated, or the ulcer is described only as a foot ulcer, check documentation before coding. Code the underlying disease first when it is clearly documented.
Do not use for
Do not use this code for type 1 or type 2 diabetes, or for ulcers without a documented diabetic relationship. Do not use it for diabetic foot ulcers; check documentation.
Coding tip
Confirm the underlying condition and ulcer location in the same record before assigning E08.622.
