ICD-10 Code L97.418 – Non-pressure chronic ulcer of right heel and midfoot with other specified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.418 – Non-pressure chronic ulcer of right heel and midfoot with other specified severity
What it is
This code identifies a chronic, non-pressure ulcer on the right heel or midfoot with a documented severity that is not otherwise specified. Use it when the record clearly places the ulcer on the right side and in this anatomic area.
Clinical signs
Typical findings include an open skin lesion with delayed healing, localized tissue loss, and chronic wound documentation. Clinical features vary; refer to documentation for the exact severity and depth.
When to use this code
Use this code when the provider documents a chronic ulcer of the right heel or midfoot and specifies a severity category that maps to “other specified severity.” It is appropriate for non-pressure ulcers from causes such as vascular, diabetic, or other chronic etiologies when the diagnosis is recorded that way.
Make sure the laterality and site are explicit in the note. If the chart does not clearly support the right heel or midfoot location, or the severity is unclear, check documentation.
Do not use for
Do not use this code for pressure ulcers, ulcers of the left foot, or ulcers at other foot sites. Do not assign it when the record does not support a chronic non-pressure ulcer diagnosis.
Coding tip
Confirm both the anatomic site and the documented severity before coding, because missing detail can lead to a different L97 category.
