ICD-10 Code L98.A228 – Non-pressure chronic ulcer of left forearm with other specified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A228 – Non-pressure chronic ulcer of left forearm with other specified severity
What it is
This code identifies a chronic, non-pressure ulcer on the left forearm with a documented severity that is not captured by the more specific ulcer severity options. Use it when the record clearly states the site and that the ulcer is chronic.
Clinical signs
Clinical features vary; refer to documentation. Typical ulcer findings include an open skin lesion with delayed healing, drainage, or surrounding skin breakdown, and the provider must document the left forearm location and the specified severity.
When to use this code
Use L98.A228 when the clinician documents a chronic non-pressure ulcer on the left forearm and specifies a severity that fits this code. It is appropriate when the ulcer is not due to pressure injury and the laterality is clearly left. Check documentation if the severity wording is unclear or incomplete.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers on another body site. If the chart does not support chronicity, left-sided location, or the stated severity, check documentation before coding.
Coding tip
Always verify the exact ulcer wording, laterality, and severity in the provider note before assigning this code.
