ICD-10 Code L97.319 – Non-pressure chronic ulcer of right ankle with unspecified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.319 – Non-pressure chronic ulcer of right ankle with unspecified severity
What it is
This code identifies a chronic ulcer on the right ankle that is not caused by pressure and whose severity is not further specified. Use it when the record confirms location and chronicity, but no deeper detail is documented.
Clinical signs
Typical findings include an open skin lesion over the right ankle that persists over time and may show drainage, surrounding skin changes, or delayed healing. Clinical features vary; refer to documentation.
When to use this code
Use L97.319 when the provider documents a chronic, non-pressure ulcer on the right ankle and does not state the depth or another more specific severity level. It is appropriate for outpatient, inpatient, or wound-care records when laterality and site are clear. If the note names a different ankle site or a pressure injury, choose another code.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers at another location such as the foot or lower leg. Check documentation if the record does not clearly support a chronic non-pressure ulcer.
Coding tip
Confirm that “right ankle” and “chronic non-pressure ulcer” are both documented before assigning L97.319.
