ICD-10 Code L89.30 – Pressure ulcer of unspecified buttock (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.30 – Pressure ulcer of unspecified buttock
What it is
This code identifies a pressure ulcer located on the buttock when the exact side is not documented. Use it for a pressure injury caused by sustained pressure, with the site recorded only as “buttock.”
Clinical signs
Typical findings include localized skin breakdown, discoloration, or an open sore over the buttock. Clinical features vary; refer to documentation for stage, depth, and whether the wound involves tissue loss.
When to use this code
Use L89.30 when the provider documents a pressure ulcer of the buttock but does not specify left or right. It also fits cases where the site is clearly the buttock and no more precise location is available. Check documentation if the record later identifies laterality or a different pressure injury site.
Do not use for
Do not use this code for non-pressure ulcers, skin tears, or wounds from friction, moisture, or trauma. If the buttock side is documented, choose the more specific code instead.
Coding tip
Review wound notes carefully for laterality and stage before assigning L89.30.
