ICD-10 Code L98.495 – Non-pressure chronic ulcer of skin of other sites with muscle involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.495 – Non-pressure chronic ulcer of skin of other sites with muscle involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer on a skin site other than the usual pressure areas, with involvement extending to muscle and no necrosis. Use it when the documentation clearly supports depth to muscle.
Clinical signs
Typical findings include an open ulcer with visible depth into muscle tissue and a chronic course. Clinical features vary; refer to documentation for site, chronicity, and whether necrosis is absent.
When to use this code
Use L98.495 when the record states a chronic non-pressure ulcer at an other site and specifies muscle involvement without necrosis. It fits documentation that distinguishes this lesion from pressure injuries and from ulcers limited to skin or subcutaneous tissue.
If the note names the anatomic site but not the depth, check documentation before assigning this code. You should also confirm that the ulcer is chronic and that necrosis is not reported.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers with documented necrosis. If the ulcer depth is unclear or limited to skin only, check documentation.
Coding tip
Code only when the provider documents both muscle involvement and absence of necrosis; otherwise, query for specificity.
