ICD-10 Code L97.914 – Non-pressure chronic ulcer of unspecified part of right lower leg with necrosis of bone (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.914 – Non-pressure chronic ulcer of unspecified part of right lower leg with necrosis of bone
What it is
This code identifies a chronic, non-pressure ulcer on the right lower leg when the exact site is not specified and the wound has necrosis of bone. Use it for a persistent open lesion not caused by pressure injury.
Clinical signs
Expect a nonhealing ulcer with exposed or necrotic bone documented in the right lower leg. Clinical features vary; refer to documentation for depth, drainage, infection, or surrounding tissue changes.
When to use this code
Use L97.914 when the record states a chronic ulcer of the right lower leg, the location is unspecified within that leg, and bone necrosis is present. This code fits outpatient, inpatient, or wound-care documentation that supports all elements.
If laterality, chronicity, or bone involvement is unclear, check documentation before assigning the code. Do not infer necrosis of bone from a severe ulcer alone.
Do not use for
Do not use this code for pressure ulcers, ulcers of the foot or ankle, or ulcers without documented bone necrosis. If the right lower leg site is specified more precisely, choose the more exact code.
Coding tip
Confirm three details in the note: chronic non-pressure ulcer, right lower leg, and necrosis of bone; missing any one of them changes the code selection.
