ICD-10 Code E08.51 – Diabetes mellitus due to underlying condition with diabetic peripheral angiopathy without gangrene (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E08.51 – Diabetes mellitus due to underlying condition with diabetic peripheral angiopathy without gangrene
What it is
This code identifies diabetes caused by another underlying condition, with peripheral blood vessel disease affecting the legs or feet. The vascular complication is present, but there is no gangrene.
Clinical signs
Look for documentation of diabetes plus peripheral angiopathy, such as poor circulation, diminished pulses, or ischemic pain in the extremities. Clinical features vary; refer to documentation.
When to use this code
Use E08.51 when the record states diabetes is due to an underlying condition and the patient has diabetic peripheral angiopathy without gangrene. The note should link the vascular complication to the diabetes. If the cause of diabetes or the vascular complication is unclear, check documentation.
Do not use for
Do not use this code if gangrene is present, because a different code applies. Also avoid it when diabetes is not documented as due to an underlying condition or when peripheral angiopathy is not specified.
Coding tip
Confirm both the secondary diabetes cause and the “without gangrene” wording before assigning E08.51.
