ICD-10 Code L98.A195 – Non-pressure chronic ulcer of unspecified upper arm with muscle involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A195 – Non-pressure chronic ulcer of unspecified upper arm with muscle involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on the upper arm with involvement of muscle and no documented necrosis. Use it when the record specifies the site as unspecified upper arm and confirms muscle involvement.
Clinical signs
Typical findings include a persistent open ulcer on the upper arm with depth extending to muscle tissue. Clinical features vary; refer to documentation for laterality, size, drainage, infection, or other wound details.
When to use this code
Use this code when the provider documents a chronic ulcer of the unspecified upper arm and states that muscle is involved, but there is no evidence of tissue death. It fits wound assessments, progress notes, or discharge summaries that clearly support depth and location. If the note does not confirm muscle involvement, check documentation.
Do not use for
Do not use it for pressure ulcers, ulcers at a different arm site, or wounds limited to skin or subcutaneous tissue. If necrosis is documented, this code is not appropriate.
Coding tip
Verify both the anatomic site and the depth of involvement before assigning this code.
