ICD-10 Code L97.201 – Non-pressure chronic ulcer of unspecified calf limited to breakdown of skin (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.201 – Non-pressure chronic ulcer of unspecified calf limited to breakdown of skin
What it is
This code identifies a chronic, non-pressure ulcer on the calf when the skin breakdown is limited to the skin layer. Use it when the documentation does not specify left or right calf.
Clinical signs
Typical findings include an open, persistent wound on the calf with superficial skin loss. Clinical features vary; refer to documentation for laterality, depth, and whether infection or necrosis is present.
When to use this code
Use L97.201 when the provider documents a chronic ulcer of the calf and states that the breakdown is limited to skin. It also fits cases where the calf is specified but the side is not. Confirm that the ulcer is non-pressure and not a decubitus injury.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers documented on another lower-extremity site. Check documentation if the wound extends beyond skin breakdown or if laterality is known.
Coding tip
Verify the ulcer location, pressure status, and depth before assigning L97.201.
