ICD-10 Code L98.A325 – Non-pressure chronic ulcer of left hand with muscle involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A325 – Non-pressure chronic ulcer of left hand with muscle involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on the left hand that extends into muscle but shows no necrosis. Use it when documentation specifies both the left hand site and muscle involvement.
Clinical signs
Typical findings include an open, persistent wound on the left hand with exposed or affected muscle tissue. Clinical features vary; refer to documentation for depth, chronicity, and absence of necrotic tissue.
When to use this code
Use this code when the provider documents a chronic ulcer of the left hand with muscle involvement and explicitly states there is no evidence of necrosis. It may apply to wound care notes, specialist assessments, or problem lists that clearly identify the site and depth. Check documentation if laterality or tissue depth is unclear.
Do not use for
Do not use it for pressure ulcers, ulcers without muscle involvement, or ulcers with necrosis. If the record does not confirm the left hand or chronic non-pressure nature, check documentation.
Coding tip
Verify laterality, ulcer depth, and necrosis status before assigning L98.A325.
