ICD-10 Code L97.318 – Non-pressure chronic ulcer of right ankle with other specified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.318 – Non-pressure chronic ulcer of right ankle with other specified severity
What it is
This code identifies a chronic, non-pressure ulcer located on the right ankle. “Other specified severity” means the record documents severity beyond simple skin breakdown, but not the exact category needed for a more specific ulcer code.
Clinical signs
Typical findings include a persistent open wound at the right ankle with surrounding skin changes, drainage, or delayed healing. Clinical features vary; refer to documentation.
When to use this code
Use L97.318 when the provider documents a chronic non-pressure ulcer on the right ankle and specifies severity as “other specified” or equivalent wording. Code it only when the site is clearly the right ankle and the ulcer is not due to pressure injury. If the chart gives a different location or a more specific severity, select the documented code instead.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers on another site. Check documentation if the record does not clearly support a chronic non-pressure ulcer of the right ankle.
Coding tip
Verify laterality, ulcer type, and documented severity before assigning L97.318.
