ICD-10 Code L97.113 – Non-pressure chronic ulcer of right thigh with necrosis of muscle (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.113 – Non-pressure chronic ulcer of right thigh with necrosis of muscle
What it is
This code identifies a chronic, non-pressure ulcer on the right thigh with muscle necrosis. Use it when documentation shows a full-thickness wound that has damaged muscle and is not caused by pressure.
Clinical signs
Typical findings include a persistent open ulcer on the right thigh with exposed or necrotic muscle tissue. Clinical features vary; refer to documentation for depth, laterality, and wound characteristics.
When to use this code
Use L97.113 when the provider documents a chronic ulcer of the right thigh and specifically states necrosis of muscle. It may apply in wound care, vascular, diabetic, or other chronic ulcer notes. Code only when the record clearly supports non-pressure origin and site.
Do not use for
Do not use this code for pressure injuries, acute wounds, or ulcers without documented muscle necrosis. If the ulcer site or depth is unclear, check documentation.
Coding tip
Verify both laterality and tissue depth before assigning L97.113.
