ICD-10 Code L97.202 – Non-pressure chronic ulcer of unspecified calf with fat layer exposed (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.202 – Non-pressure chronic ulcer of unspecified calf with fat layer exposed
What it is
This code identifies a chronic, non-pressure ulcer on the calf where the fat layer is exposed. Use it when the record specifies the calf but does not document right or left side.
Clinical signs
Typical findings include a persistent open wound on the calf with visible subcutaneous fat. Clinical features vary; refer to documentation for laterality, depth, and any associated infection or necrosis.
When to use this code
Use L97.202 when the provider documents a chronic ulcer of the calf and states that fat is exposed, but laterality is not specified. This code fits non-pressure ulcers only, including wounds described as chronic, nonhealing, or full-thickness to fat. Check documentation if the site is instead the ankle, foot, or another lower-extremity location.
Do not use for
Do not use this code for pressure ulcers, traumatic wounds, or ulcers without fat-layer exposure. If the chart identifies right or left calf, choose the laterality-specific code instead.
Coding tip
Confirm both the exact calf site and the absence of laterality before assigning L97.202.
