ICD-10 Code L98.A22 – Non-pressure chronic ulcer of left forearm (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A22 – Non-pressure chronic ulcer of left forearm
What it is
This code identifies a chronic, non-pressure ulcer located on the left forearm. Use it when documentation clearly describes a persistent skin breakdown or open sore in that specific site.
Clinical signs
Typical findings include an open lesion with delayed healing, surrounding skin changes, drainage, or granulation tissue. Clinical features vary; refer to documentation.
When to use this code
Use L98.A22 when the provider documents a chronic ulcer of the left forearm and does not identify a pressure injury. It fits outpatient, inpatient, or wound-care records that specify the site and chronic nature. If the record is unclear about cause or location, check documentation.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers on another body site. If the note does not confirm a chronic non-pressure ulcer of the left forearm, check documentation.
Coding tip
Confirm both “chronic” and “left forearm” in the provider note before assigning this code.
