ICD-10 Code L97.32 – Non-pressure chronic ulcer of left ankle (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.32 – Non-pressure chronic ulcer of left ankle
What it is
This code identifies a chronic, non-pressure ulcer located on the left ankle. It applies when the ulcer is not caused by pressure injury and the left ankle site is documented.
Clinical signs
You may see an open skin lesion with delayed healing, drainage, surrounding skin changes, or exposed tissue. Clinical features vary; refer to documentation.
When to use this code
Use L97.32 when the provider documents a chronic ulcer of the left ankle and specifies that it is non-pressure. Code it for ongoing ulcers managed over time, including wounds described as persistent, slow to heal, or recurrent.
Confirm the left ankle location in the note and avoid guessing laterality. If the record does not clearly state chronicity or ulcer type, check documentation before assigning the code.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers at another site. Do not assign it when the documentation only says “wound” without confirming a chronic non-pressure ulcer.
Coding tip
Always verify laterality and ulcer type together; missing either detail can lead to the wrong ICD-10 code.
