Pressure-induced deep tissue damage of unspecified buttock

This code signifies deep tissue injury (DTI) caused by sustained pressure, specifically located on an unspecified buttock. DTI is characterized by persistent non-blanchable deep red, maroon, or purple discoloration, or an epidermal blister, indicating damage to underlying soft tissue. It often precedes the development of a full-thickness pressure ulcer.

Apply this code when documentation clearly identifies a pressure-induced deep tissue injury on the buttock, but the specific left or right side is not documented. This diagnosis is typically made based on visual assessment and palpation, noting the characteristic discoloration or blister. Documentation should explicitly state "deep tissue injury" or "DTI" and the anatomical location.

• Do not use this code if a full-thickness pressure ulcer has developed; instead, code the appropriate stage of the pressure ulcer.
• Ensure documentation specifies "deep tissue injury" and not just "pressure ulcer" if this code is to be used.
• If the specific buttock (left or right) is documented, use the more specific codes L89.316 or L89.326.
