ICD-10 Code I96 – Gangrene, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I96 – Gangrene, not elsewhere classified
What it is
I96 identifies gangrene when the tissue death is not classified elsewhere. Use it for necrotic tissue loss caused by severe loss of blood supply or infection when the record does not specify a more exact cause.
Clinical signs
Typical findings include black or dead tissue, foul odor, skin discoloration, and loss of sensation or pain in the affected area. Clinical features vary; refer to documentation.
When to use this code
Use I96 when the provider documents gangrene and does not link it to a more specific diagnosis, such as diabetic or gas gangrene. It may apply to digits, foot, or other body sites if the note supports gangrene and no better code is available.
Check whether the record describes the cause, location, or associated condition, since those details may require a different code. Code the documented condition exactly as stated.
Do not use for
Do not use I96 for diabetic gangrene, gas gangrene, or gangrene with a documented underlying condition that has a more specific code. Do not assign it when the chart only describes ulcer, ischemia, or necrosis without gangrene.
Coding tip
Confirm that the provider actually documented gangrene, because “necrosis” alone is not enough for I96.
