ICD-10 Code L97.116 – Non-pressure chronic ulcer of right thigh with bone involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.116 – Non-pressure chronic ulcer of right thigh with bone involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on the right thigh that extends to the bone, with no documented necrosis. Use it when the record clearly shows ulcer depth and location.
Clinical signs
Findings usually include an open wound on the right thigh with prolonged nonhealing and exposed or involved bone. Clinical features vary; refer to documentation.
When to use this code
Use L97.116 when the provider documents a chronic ulcer of the right thigh with bone involvement and states there is no necrosis. You should also confirm the site is the right thigh, not another lower-extremity location.
If the note only says “ulcer” or does not specify bone involvement, check documentation before coding. Assign this code only when the depth and absence of necrosis are explicit.
Do not use for
Do not use this code for pressure ulcers, ulcers without bone involvement, or ulcers with documented necrosis. Check documentation if the laterality or anatomic site is unclear.
Coding tip
Verify the exact site, chronicity, depth, and necrosis status in the provider note before assigning L97.116.
