ICD-10 Code L98.A318 – Non-pressure chronic ulcer of right hand with other specified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A318 – Non-pressure chronic ulcer of right hand with other specified severity
What it is
This code identifies a chronic, non-pressure ulcer on the right hand with a documented severity that is not otherwise specified. Use it when the record confirms a persistent skin break on the right hand and the provider documents the ulcer’s severity category.
Clinical signs
Typical findings include an open or nonhealing wound on the right hand, with local tissue breakdown and delayed healing. Clinical features vary; refer to documentation for depth, drainage, pain, infection, or other descriptors.
When to use this code
Use this code when the provider documents a chronic non-pressure ulcer of the right hand and specifies “other specified severity.” It fits outpatient, inpatient, or wound-care notes when the ulcer is not caused by pressure and laterality is clearly right hand. Check documentation if severity wording is unclear.
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 support a chronic non-pressure ulcer of the right hand, code the documented condition instead.
Coding tip
Verify both laterality and the exact severity wording before assigning L98.A318.
