ICD-10 Code L89.31 – Pressure ulcer of right buttock (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.31 – Pressure ulcer of right buttock
What it is
This code identifies a pressure ulcer located on the right buttock. Use it when documentation specifies the site but does not provide a more detailed stage or depth in the code title.
Clinical signs
Pressure ulcers typically present as localized skin or tissue injury over a pressure-bearing area. Findings may include redness, open skin, drainage, or tissue loss; clinical features vary, so refer to documentation.
When to use this code
Use L89.31 when the record clearly documents a pressure ulcer of the right buttock. It is appropriate for wound assessments, inpatient problem lists, and follow-up visits when the ulcer remains an active diagnosis. If staging or laterality differs, code the documented detail instead.
Do not use for
Do not use this code for non-pressure wounds, skin irritation, or ulcers at another site. If the chart does not confirm a pressure ulcer on the right buttock, check documentation.
Coding tip
Verify the anatomic site carefully, because buttock laterality matters and incorrect side assignment can change the code.
