ICD-10 Code L89.319 – Pressure ulcer of right buttock, unspecified stage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.319 – Pressure ulcer of right buttock, unspecified stage
What it is
This code identifies a pressure ulcer located on the right buttock when the stage is not documented or cannot be determined. It tells you the wound is pressure-related, but the depth or severity is unspecified.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include localized skin breakdown, redness, open ulceration, or tissue damage over the right buttock from prolonged pressure.
When to use this code
Use this code when the provider documents a pressure ulcer on the right buttock and does not specify the stage. It is also appropriate when the record confirms the site but staging is unavailable or unclear. You should code the documented laterality and location exactly as written.
Do not use for
Do not use this code if the ulcer is staged, because a more specific pressure ulcer code applies. Do not use it for non-pressure skin breakdown, moisture-associated damage, or ulcers at another site.
Coding tip
Check the note for stage and exact location before assigning an unspecified code.
