ICD-10 Code L98.445 – Non-pressure chronic ulcer of chest with muscle involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.445 – Non-pressure chronic ulcer of chest with muscle involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on the chest that extends into muscle but does not show necrosis. Use it when documentation confirms depth and location, and the ulcer is not caused by pressure.
Clinical signs
Findings may include a persistent open wound on the chest with exposed or involved muscle tissue. Clinical features vary; refer to documentation for depth, chronicity, and whether necrosis is absent.
When to use this code
Use L98.445 when the record clearly states a chronic ulcer of the chest with muscle involvement and no necrotic tissue. It is appropriate for provider documentation that specifies the site and depth. Check documentation if the ulcer cause or stage is unclear.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers without muscle involvement. If necrosis is documented, or the site is not the chest, select the more accurate code.
Coding tip
Match the code to the documented ulcer depth and anatomic site exactly, and confirm that “without necrosis” is stated.
