ICD-10 Code L98.479 – Non-pressure chronic ulcer of groin with unspecified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.479 – Non-pressure chronic ulcer of groin with unspecified severity
What it is
This code identifies a chronic ulcer in the groin area that is not caused by pressure and whose severity is not documented. Use it when the record confirms the location and chronic ulcer, but does not specify depth or stage.
Clinical signs
Typical findings include a persistent open skin lesion in the groin with delayed healing. Clinical features vary; refer to documentation for drainage, tissue loss, pain, or signs of infection.
When to use this code
Use L98.479 when the provider documents a chronic non-pressure ulcer of the groin and does not assign a more specific severity. It may also fit when the note describes an ulcer in this location but leaves staging or depth unclear. Check documentation if the cause is pressure-related or if another ulcer site is recorded.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers at a different anatomic site. If the chart specifies severity or another more precise diagnosis, code that instead.
Coding tip
Confirm both the location and the “non-pressure” wording before assigning L98.479.
