ICD-10 Code L98.A226 – Non-pressure chronic ulcer of left forearm with bone involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A226 – Non-pressure chronic ulcer of left forearm with bone involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on the left forearm that extends to bone, with no documented necrosis. Use it when the record clearly shows a persistent skin breakdown in that location and depth.
Clinical signs
Typical findings include an open ulcer on the left forearm with deep tissue involvement and documentation of bone exposure or bone involvement. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a chronic ulcer of the left forearm and specifies bone involvement without necrosis. It is appropriate when the ulcer is non-pressure related and the site is the left forearm. Check documentation if laterality, depth, or necrosis status is unclear.
Do not use for
Do not use this code for pressure ulcers, ulcers without bone involvement, or ulcers with documented necrosis. If the chart does not confirm the left forearm or the chronic nature, check documentation.
Coding tip
Verify both laterality and depth documentation before assigning L98.A226.
