ICD-10 Code L89.326 – Pressure-induced deep tissue damage of left buttock (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.326 – Pressure-induced deep tissue damage of left buttock
What it is
This code identifies a pressure injury with deep tissue damage on the left buttock. It means the skin and underlying tissue have been injured by prolonged pressure or pressure with shear.
Clinical signs
Look for persistent discoloration, localized pain, and tissue that may feel boggy, firm, or warmer or cooler than nearby skin. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents deep tissue pressure damage specifically on the left buttock. It may appear in wound assessments, nursing notes, or discharge summaries. Do not infer laterality or stage if the record does not state it.
Do not use for
Do not use this code for superficial pressure redness, open ulcers without deep tissue damage, or pressure injuries on another site. Check documentation if the location or severity is unclear.
Coding tip
Verify that the record clearly states both deep tissue damage and the left buttock before assigning L89.326.
