ICD-10 Code L97.102 – Non-pressure chronic ulcer of unspecified thigh with fat layer exposed (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.102 – Non-pressure chronic ulcer of unspecified thigh with fat layer exposed
What it is
This code identifies a chronic, non-pressure ulcer on the thigh where the wound extends into the fat layer. Use it when the thigh site is documented but the laterality is not specified.
Clinical signs
Typical findings include a persistent open skin lesion on the thigh with visible subcutaneous fat. Clinical features vary; refer to documentation for ulcer duration, depth, and whether infection or necrosis is present.
When to use this code
Use L97.102 when the provider documents a chronic non-pressure ulcer of the thigh and specifies fat layer exposure, but does not specify right or left side. It may also apply when the ulcer is described by depth and location alone. Check documentation if the note suggests a different ulcer type or a pressure injury.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers at other body sites. If the record identifies right or left thigh, use the laterality-specific code instead.
Coding tip
Confirm chronicity, non-pressure etiology, and laterality before assigning L97.102.
