ICD-10 Code L98.456 – Non-pressure chronic ulcer of neck with bone involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.456 – Non-pressure chronic ulcer of neck with bone involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on the neck that extends to bone. It applies when documentation shows bone involvement but no necrosis.
Clinical signs
Expect a persistent open wound in the neck region with documented depth to bone. Clinical features vary; refer to documentation for signs of chronicity, exposed deeper structures, or related wound findings.
When to use this code
Use this code when the record clearly states a chronic non-pressure ulcer of the neck and specifies bone involvement. It is appropriate when the provider documents no evidence of necrosis. If the site, depth, or tissue involvement is unclear, check documentation.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers without bone involvement. It is also wrong when necrosis is documented or when the neck is not the affected site.
Coding tip
Confirm the ulcer location, chronicity, and depth in the note before assigning L98.456.
