ICD-10 Code L98.459 – Non-pressure chronic ulcer of neck with unspecified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.459 – Non-pressure chronic ulcer of neck with unspecified severity
What it is
This code identifies a chronic skin ulcer on the neck that is not caused by pressure and whose severity is not documented. Use it when the record confirms a persistent ulcer but does not specify depth or stage.
Clinical signs
Typical documentation may describe an open sore, delayed healing, drainage, or surrounding skin irritation on the neck. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a chronic non-pressure ulcer of the neck and does not record a more specific severity. It is also appropriate when the ulcer is described as chronic but the chart lacks details needed for a more precise code. Check documentation if the cause or site is unclear.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers at other body sites. Do not assign it when documentation supports a more specific ulcer severity.
Coding tip
Query for ulcer severity and exact anatomic site before defaulting to unspecified.
