ICD-10 Code L97.408 – Non-pressure chronic ulcer of unspecified heel and midfoot with other specified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.408 – Non-pressure chronic ulcer of unspecified heel and midfoot with other specified severity
What it is
This code identifies a chronic, non-pressure ulcer on the heel or midfoot when the laterality is not specified and the ulcer severity is documented as “other specified.” It applies to skin breakdown that is not caused by pressure.
Clinical signs
Typical findings include an open wound with delayed healing, drainage, or surrounding skin changes at the heel or midfoot. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states a chronic non-pressure ulcer of the heel or midfoot, but does not identify right or left side. You should also confirm that the provider documents the ulcer severity as other specified, not a different depth or stage. Check documentation if the site or severity is unclear.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers at a different foot location. If the laterality is documented, choose the more specific code instead.
Coding tip
Verify both the anatomic site and laterality before assigning L97.408, because unspecified heel and midfoot codes are only appropriate when the chart lacks side detail.
