ICD-10 Code L98.A328 – Non-pressure chronic ulcer of left hand with other specified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A328 – Non-pressure chronic ulcer of left hand with other specified severity
What it is
This code identifies a chronic, non-pressure ulcer on the left hand with a documented severity that is not otherwise specified by another code. Use it for a persistent skin break or open sore when pressure injury is not the cause.
Clinical signs
Typical findings include an open lesion on the left hand with delayed healing, tissue loss, drainage, or surrounding skin changes. Clinical features vary; refer to documentation for the ulcer’s depth, severity, and chronicity.
When to use this code
Use this code when the record clearly states a chronic non-pressure ulcer on the left hand and the provider documents “other specified severity.” It fits cases where the ulcer is not a pressure ulcer and is not described by a more specific severity code. Check documentation if the site, laterality, or severity is unclear.
Do not use for
Do not use this code for pressure ulcers, traumatic wounds, or acute skin injuries. Also avoid it when the chart does not confirm the left hand or the documented severity.
Coding tip
Match the code to the exact ulcer location, laterality, and severity wording in the provider note.
