ICD-10 Code L97.106 – Non-pressure chronic ulcer of unspecified thigh with bone involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.106 – Non-pressure chronic ulcer of unspecified thigh with bone involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on an unspecified thigh that extends to the bone but shows no necrosis. Use it when the documentation clearly states bone involvement and does not describe dead tissue.
Clinical signs
Clinical features vary; refer to documentation. Typical records may describe a persistent open wound on the thigh with exposed or involved bone, chronicity, and absence of necrotic tissue.
When to use this code
Use this code when the provider documents a chronic ulcer of the thigh, specifies bone involvement, and states there is no evidence of necrosis. It also applies when the thigh site is not further identified as right or left. If the record is unclear about depth or tissue involvement, check documentation.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers with necrosis. Do not assign it if the thigh side is documented and a more specific code is available.
Coding tip
Confirm three elements in the note: chronic ulcer, thigh location, and bone involvement without necrosis.
