ICD-10 Code L98.474 – Non-pressure chronic ulcer of groin with necrosis of bone (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.474 – Non-pressure chronic ulcer of groin with necrosis of bone
What it is
This code identifies a chronic, non-pressure ulcer in the groin area that extends to and involves bone necrosis. Use it when documentation clearly states both the ulcer location and the bone involvement.
Clinical signs
Typical findings include a persistent open wound in the groin with exposed or necrotic bone, often with delayed healing. Clinical features vary; refer to documentation.
When to use this code
Use L98.474 when the provider documents a chronic non-pressure ulcer of the groin and specifically notes necrosis of bone. It is appropriate for wounds described as deep enough to affect bone, not just skin or subcutaneous tissue. Check documentation if the site or depth is unclear.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers in other anatomic sites. It also should not be used when bone involvement is not documented.
Coding tip
Verify both the groin location and the phrase “necrosis of bone” in the record before assigning this code.
