ICD-10 Code L97.128 – Non-pressure chronic ulcer of left thigh with other specified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.128 – Non-pressure chronic ulcer of left thigh with other specified severity
What it is
This code identifies a chronic, non-pressure ulcer on the left thigh with a severity not otherwise specified in the code title. Use it when documentation confirms the site and that the ulcer is not caused by pressure.
Clinical signs
Typical findings include a persistent open sore on the left thigh with skin breakdown and delayed healing. Clinical features vary; refer to documentation for depth, tissue involvement, and any stated severity.
When to use this code
Use L97.128 when the record clearly states a chronic ulcer on the left thigh and does not describe it as a pressure injury. It is appropriate when the provider documents “other specified severity” or an equivalent severity term. If the chart does not support the site or ulcer type, check documentation.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers at a different anatomic site. If the ulcer severity is not documented, check documentation rather than guessing.
Coding tip
Verify both laterality and non-pressure etiology before assigning L97.128.
