ICD-10 Code L98.A326 – Non-pressure chronic ulcer of left hand with bone involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A326 – Non-pressure chronic ulcer of left hand with bone involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on the left hand that extends to bone, with no documented necrosis. Use it when the record clearly shows bone involvement and does not describe dead tissue.
Clinical signs
Typical findings include a persistent open wound on the left hand, exposed or involved bone, and delayed healing. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a chronic ulcer of the left hand and specifies bone involvement without necrosis. It fits wound notes, operative reports, or specialist assessments that confirm depth and laterality. Check documentation if the note is unclear about necrosis or site.
Do not use for
Do not use it for pressure ulcers, acute wounds, or ulcers without bone involvement. Avoid it when necrosis is documented or when the ulcer site is not the left hand.
Coding tip
Confirm both laterality and depth in the record before assigning L98.A326.
