ICD-10 Code L97.506 – Non-pressure chronic ulcer of other part of unspecified foot with bone involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L97.506 – Non-pressure chronic ulcer of other part of unspecified foot with bone involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on another part of an unspecified foot, with bone involvement but no necrosis. Use it when the record shows a long-standing open wound that extends to bone.
Clinical signs
Documentation may describe an ulcer that is slow to heal, deep, and probing to bone or showing exposed bone. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a chronic foot ulcer in an unspecified foot location and states bone involvement without necrosis. It fits cases where the ulcer is not due to pressure and the site is not a heel or toe. If laterality or a more specific foot site is documented, code that detail instead.
Do not use for
Do not use this code for pressure ulcers, ulcers with necrosis, or ulcers limited to skin or subcutaneous tissue only. Do not use it when the chart identifies a more specific foot location or laterality.
Coding tip
Check the wound description carefully for bone involvement and the exact foot site before assigning L97.506.
