ICD-10 Code L97.428 – Non-pressure chronic ulcer of left heel and midfoot with other specified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.428 – Non-pressure chronic ulcer of left heel and midfoot with other specified severity
What it is
This code identifies a chronic, non-pressure ulcer on the left heel or midfoot with a documented severity that is not otherwise classified in the code set. Use it for a persistent skin breakdown in that anatomic area when the record specifies “other specified severity.”
Clinical signs
Typical findings include an open ulcer, local tissue loss, and delayed healing on the left heel or midfoot. Clinical features vary; refer to documentation for the described depth, severity, and any associated drainage, pain, or surrounding skin changes.
When to use this code
Use this code when the provider documents a chronic non-pressure ulcer on the left heel or midfoot and specifically states a severity that fits “other specified severity.” It is appropriate when the location is clear and the ulcer is not caused by pressure. If the chart does not clearly identify severity or laterality, check documentation before coding.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers at a different foot location. Also avoid it when the record does not support the left-sided heel or midfoot site.
Coding tip
Confirm both laterality and the documented severity wording before assigning L97.428.
