ICD-10 Code L98.458 – Non-pressure chronic ulcer of neck with other specified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.458 – Non-pressure chronic ulcer of neck with other specified severity
What it is
This code identifies a chronic, non-pressure ulcer located on the neck with a severity not captured by the other specific ulcer codes. Use it for a persistent skin breakdown that is not caused by pressure alone.
Clinical signs
Typical findings include an open sore on the neck with delayed healing, drainage, or surrounding skin changes. Clinical features vary; refer to documentation.
When to use this code
Use L98.458 when the record clearly documents a chronic non-pressure ulcer of the neck and the provider specifies an “other specified severity” level. This is appropriate when the ulcer is not pressure-related and the severity does not fit another listed category. Check documentation for location and exact wording.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers at another body site. If the note does not confirm chronicity or severity, check documentation.
Coding tip
Match the code to the provider’s exact ulcer severity wording and anatomic site.
