ICD-10 Code L98.475 – Non-pressure chronic ulcer of groin with muscle involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.475 – Non-pressure chronic ulcer of groin with muscle involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer in the groin that extends into muscle but shows no necrosis. Use it when the documentation clearly states the groin location and the depth of tissue involvement.
Clinical signs
Typical findings include a persistent open sore in the groin with visible tissue loss and involvement of muscle. Clinical features vary; refer to documentation for depth, chronicity, and any reported absence of necrotic tissue.
When to use this code
Use L98.475 when the provider documents a chronic ulcer of the groin with muscle involvement and specifically notes no necrosis. This applies to non-pressure ulcers only, such as wounds caused by local tissue breakdown or other non-pressure mechanisms. If the record does not confirm muscle involvement, check documentation before coding.
Do not use for
Do not use this code for pressure ulcers, ulcers in other anatomic sites, or wounds limited to skin or subcutaneous tissue. Do not assign it if necrosis is present or if the depth is unclear.
Coding tip
Verify both the site and depth in the provider note, because ulcer location and tissue level drive code selection.
