ICD-10 Code L97.50 – Non-pressure chronic ulcer of other part of unspecified foot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.50 – Non-pressure chronic ulcer of other part of unspecified foot
What it is
This code identifies a chronic ulcer on another part of the foot that is not caused by pressure. Use it when the documentation specifies a non-pressure ulcer but does not name a more exact foot location.
Clinical signs
Typical findings include a persistent open sore on the foot with slow healing, drainage, or surrounding skin breakdown. Clinical features vary; refer to documentation for the exact site and ulcer characteristics.
When to use this code
Use L97.50 when the record states a chronic non-pressure ulcer of the foot and the location is documented as “other part” or is not more specifically identified. It may apply when the ulcer is on a foot area other than heel or toe. Confirm laterality and any deeper detail if documented.
Do not use for
Do not use this code for pressure ulcers, traumatic wounds, or ulcers with a more specific foot site already documented. If the chart names the heel, toe, or another exact location, check documentation for a more precise code.
Coding tip
Capture the exact ulcer location and type first; if the foot site is vague, this code may fit, but more specific documentation should guide coding.
