ICD-10 Code L97.528 – Non-pressure chronic ulcer of other part of left foot with other specified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.528 – Non-pressure chronic ulcer of other part of left foot with other specified severity
What it is
This code identifies a chronic, non-pressure ulcer on another part of the left foot, with severity documented as “other specified.” It excludes pressure injuries and applies when the ulcer is not on the heel or midfoot.
Clinical signs
Typical findings include a persistent open sore on the left foot with surrounding skin breakdown, drainage, or delayed healing. Clinical features vary; refer to documentation for the exact ulcer location and severity.
When to use this code
Use L97.528 when the record clearly states a chronic non-pressure ulcer on the left foot, located in another specified foot area, and the severity is documented as other specified. You should confirm laterality, site, and that the ulcer is not pressure-related. If the note is vague, check documentation before coding.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers on the heel or midfoot. Do not assign it if the chart does not support left-sided location or the documented severity.
Coding tip
Verify the exact foot site and ulcer type in the provider note before assigning L97.528.
