ICD-10 Code L98.478 – Non-pressure chronic ulcer of groin with other specified severity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.478 – Non-pressure chronic ulcer of groin with other specified severity
What it is
This code identifies a chronic, non-pressure ulcer located in the groin with a severity level not otherwise specified in the code set. It is used for a persistent skin breakdown in that anatomic area that is not caused by pressure.
Clinical signs
Clinical features vary; refer to documentation. You may see an open sore in the groin with delayed healing, drainage, or surrounding skin irritation, but the record should clearly describe the ulcer and its non-pressure nature.
When to use this code
Use L98.478 when the provider documents a chronic ulcer in the groin and specifies that it is non-pressure and of other specified severity. Apply it when the site is the groin and the severity does not match a more specific ulcer code. Check documentation if the record is unclear about cause, depth, or severity.
Do not use for
Do not use this code for pressure ulcers, acute wounds, or ulcers in a different body site. If the documentation does not confirm a chronic non-pressure ulcer, check documentation.
Coding tip
Confirm both the anatomic site and the non-pressure etiology before assigning the code.
