ICD-10 Code L97.328 – Non-pressure chronic ulcer of left ankle with other specified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.328 – Non-pressure chronic ulcer of left ankle with other specified severity
What it is
This code identifies a chronic ulcer on the left ankle that is not caused by pressure and has a severity not otherwise specified in the code title. Use it when the record documents a left ankle ulcer but does not fit a more specific depth or severity category.
Clinical signs
Typical findings include an open skin lesion at the left ankle with delayed healing and chronic tissue breakdown. Clinical features vary; refer to documentation for the ulcer’s exact depth, drainage, or associated skin changes.
When to use this code
Use this code when the provider documents a chronic, non-pressure ulcer located on the left ankle and specifies “other specified severity.” It is appropriate when the chart confirms the site and chronic nature, but the severity is described in a way that matches this category. Check documentation if the ulcer is due to pressure, trauma, or another cause.
Do not use for
Do not use this code for pressure ulcers or ulcers at a different site. Do not assign it when documentation supports a more specific severity code or when the ulcer type is unclear.
Coding tip
Verify laterality, chronicity, and the exact severity wording before coding L97.328.
