ICD-10 Code L97.316 – Non-pressure chronic ulcer of right ankle with bone involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.316 – Non-pressure chronic ulcer of right ankle with bone involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on the right ankle that extends to bone but shows no necrosis. Use it when the record clearly documents bone involvement without gangrene or dead tissue.
Clinical signs
Typical findings include a persistent open wound at the right ankle with exposed or involved bone. Clinical features vary; refer to documentation for depth, laterality, and whether necrosis is absent.
When to use this code
Use L97.316 when the provider documents a chronic ulcer of the right ankle and specifies bone involvement. The note should also state that there is no evidence of necrosis. If the site, depth, or laterality is unclear, check documentation before coding.
Do not use for
Do not use this code for pressure ulcers, ulcers without bone involvement, or ulcers with necrosis or gangrene. If the record describes a different ankle, side, or ulcer depth, select the matching code.
Coding tip
Confirm both laterality and depth in the provider note before assigning L97.316.
