ICD-10 Code L98.A314 – Non-pressure chronic ulcer of right hand with necrosis of bone (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A314 – Non-pressure chronic ulcer of right hand with necrosis of bone
What it is
This code identifies a chronic, non-pressure ulcer on the right hand with bone necrosis. Use it when documentation shows a persistent skin breakdown that extends to dead bone tissue, not a pressure injury.
Clinical signs
Common findings include an open ulcer on the right hand with chronic non-healing tissue loss and exposed or involved bone. Clinical features vary; refer to documentation for evidence of necrosis, depth, and laterality.
When to use this code
Use L98.A314 when the provider documents a non-pressure chronic ulcer of the right hand and specifies necrosis of bone. It applies when the site is clearly the right hand and the ulcer is chronic rather than acute. If the record does not confirm bone involvement, check documentation before coding.
Do not use for
Do not use this code for pressure ulcers, acute traumatic wounds, or ulcers without bone necrosis. It is also incorrect if the site is not the right hand or if laterality is undocumented.
Coding tip
Verify both laterality and the documented depth of involvement before assigning this code.
