ICD-10 Code L98.A329 – Non-pressure chronic ulcer of left hand with unspecified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A329 – Non-pressure chronic ulcer of left hand with unspecified severity
What it is
This code identifies a chronic, non-pressure ulcer located on the left hand when the record does not specify severity. Use it for a persistent skin breakdown not caused by pressure injury.
Clinical signs
Typical findings include an open sore on the left hand with delayed healing, drainage, or surrounding skin changes. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a chronic ulcer of the left hand and does not assign a severity level. It is appropriate when the ulcer is non-pressure in origin and laterality is clearly left. If the note describes another site or a pressure injury, choose a different code.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers on another body site. Check documentation if the record does not clearly state chronicity, location, or non-pressure cause.
Coding tip
Confirm the chart states both left hand and chronic ulcer; unspecified severity should be coded only when no more specific stage or depth is documented.
