ICD-10 Code L98.A29 – Non-pressure chronic ulcer of unspecified forearm (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A29 – Non-pressure chronic ulcer of unspecified forearm
What it is
This code identifies a chronic, non-pressure ulcer on the forearm when the exact side or more specific location is not documented. It describes a persistent skin break with tissue loss that is not caused by pressure.
Clinical signs
Typical findings include an open wound, delayed healing, drainage, or surrounding skin changes. Clinical features vary; refer to documentation for ulcer depth, laterality, and cause.
When to use this code
Use L98.A29 when the record clearly states a chronic non-pressure ulcer of the forearm but does not specify right or left side. It also fits when the provider documents an ulcer on the forearm without enough detail for a more specific code. Check documentation if the ulcer is pressure-related, traumatic, or associated with another condition.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or skin loss from trauma. If the documentation identifies a more specific ulcer type, site, or laterality, code that instead.
Coding tip
Query for laterality and ulcer etiology when the chart only says “forearm ulcer.”
