ICD-10 Code L98.41 – Non-pressure chronic ulcer of buttock (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.41 – Non-pressure chronic ulcer of buttock
What it is
This code identifies a chronic skin ulcer on the buttock that is not caused by pressure. It is used when the ulcer is persistent and documented as non-pressure in origin.
Clinical signs
Typical findings include an open sore with loss of skin or deeper tissue on the buttock. Clinical features vary; refer to documentation for wound depth, drainage, and any surrounding skin changes.
When to use this code
Use L98.41 when the record clearly states a chronic non-pressure ulcer located on the buttock. It is appropriate when the clinician documents ulceration without linking it to pressure injury or another specific cause. Check documentation if the site or cause is unclear.
Do not use for
Do not use this code for pressure ulcers, even if they are on the buttock. Also avoid it when the documentation describes a different skin lesion or does not confirm a chronic ulcer.
Coding tip
Confirm both the anatomic site and the non-pressure etiology before assigning this code.
