ICD-10 Code L89.306 – Pressure-induced deep tissue damage of unspecified buttock (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.306 – Pressure-induced deep tissue damage of unspecified buttock
What it is
This code identifies a pressure-related injury to deep soft tissue in the buttock, with the exact side not documented. It is used when the lesion is described as deep tissue damage rather than an open ulcer.
Clinical signs
Look for localized discoloration, pain, boggy or firm tissue, and possible blistering over the buttock. Clinical features vary; refer to documentation.
When to use this code
Use L89.306 when the provider documents deep tissue pressure injury or pressure-induced deep tissue damage of the buttock and does not specify left or right. It may also apply when the record clearly supports a pressure injury but laterality is not stated. Check documentation if the site is unclear.
Do not use for
Do not use this code for pressure ulcers with exposed skin loss, or when the buttock side is documented as left or right. Do not assign it if the lesion is not pressure-related.
Coding tip
Verify laterality and injury depth in the note before coding, because unspecified buttock codes should be used only when the record truly lacks side detail.
