ICD-10 Code L97.30 – Non-pressure chronic ulcer of unspecified ankle (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.30 – Non-pressure chronic ulcer of unspecified ankle
What it is
This code identifies a chronic skin ulcer at the ankle that is not caused by pressure. It is used when the documentation does not specify whether the right or left ankle is involved.
Clinical signs
Typical findings include a persistent open sore with loss of skin and surrounding tissue at the ankle. Clinical features vary; refer to documentation for depth, laterality, and any associated drainage or infection.
When to use this code
Use L97.30 when the provider documents a chronic non-pressure ulcer of the ankle but does not identify the side. It may appear in wound care, podiatry, or primary care notes when the ulcer is ongoing and not due to pressure injury. Check documentation if the record later specifies laterality or a more precise ulcer site.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers at another foot or leg location. If the note specifies right or left ankle, choose the laterality-specific code instead.
Coding tip
Confirm that “chronic,” “non-pressure,” and “ankle” are all documented before assigning L97.30.
