ICD-10 Code L97.409 – Non-pressure chronic ulcer of unspecified heel and midfoot with unspecified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.409 – Non-pressure chronic ulcer of unspecified heel and midfoot with unspecified severity
What it is
This code identifies a chronic, non-pressure ulcer located on the heel or midfoot when the exact side and severity are not documented. Use it when the record confirms a persistent skin breakdown in that area.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include an open wound with delayed healing on the heel or midfoot, often with surrounding skin changes and drainage noted in the chart.
When to use this code
Use this code when the provider documents a chronic ulcer of the heel or midfoot but does not specify right or left side, or the severity stage is not stated. It also fits when the ulcer is clearly non-pressure and no more specific L97 code is supported. Check documentation if laterality or depth is available elsewhere in the note.
Do not use for
Do not use this code for pressure ulcers, diabetic foot ulcers coded elsewhere, or ulcers with documented laterality and severity that allow a more specific code. Do not guess the site if the record is unclear.
Coding tip
Verify the ulcer’s location, chronicity, and laterality before assigning L97.409; if the note is incomplete, query for specificity.
