ICD-10 Code L98.476 – Non-pressure chronic ulcer of groin with bone involvement without evidence of necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.476 – Non-pressure chronic ulcer of groin with bone involvement without evidence of necrosis
What it is
This code identifies a chronic, non-pressure ulcer in the groin that extends to bone, but there is no documented tissue necrosis. Use it when the record clearly states bone involvement and excludes pressure injury.
Clinical signs
Typical findings include a persistent open ulcer in the groin with visible or documented extension to bone. Clinical features vary; refer to documentation for depth, chronicity, and whether necrosis is absent.
When to use this code
Use L98.476 when the clinician documents a chronic groin ulcer with bone involvement and specifically notes no necrosis. It may apply when imaging, wound assessment, or operative findings confirm bone exposure or involvement. Check documentation if the ulcer site or depth is unclear.
Do not use for
Do not use this code for pressure ulcers, ulcers without bone involvement, or cases with documented necrosis. If the site is not the groin, or the record does not support chronic ulceration, check documentation.
Coding tip
Verify both the anatomic site and the phrase “without evidence of necrosis” before assigning L98.476.
