ICD-10 Code L98.498 – Non-pressure chronic ulcer of skin of other sites with other specified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.498 – Non-pressure chronic ulcer of skin of other sites with other specified severity
What it is
This code identifies a chronic skin ulcer at an anatomic site not specifically named elsewhere, when the ulcer is not caused by pressure and the severity is otherwise specified. Use it for a documented non-pressure ulcer that does not fit a more specific site code.
Clinical signs
Typical findings include a persistent open skin lesion with tissue breakdown, drainage, or delayed healing. Clinical features vary; refer to documentation for the exact site, depth, and severity terms used by the provider.
When to use this code
Use L98.498 when the record clearly describes a chronic non-pressure ulcer on an “other site” and gives a severity description that is not captured by a more specific ICD-10 code. This is appropriate when the provider documents the ulcer location and chronicity but not a pressure-related cause. Check documentation if the site or severity is unclear.
Do not use for
Do not use this code for pressure ulcers, diabetic foot ulcers, or ulcers with a more specific anatomic site code. If the chart does not support a chronic non-pressure ulcer, choose a different diagnosis or verify the documentation.
Coding tip
Match the ulcer site and severity wording exactly to the provider note before assigning L98.498.
