ICD-10 Code L89.45 – Pressure ulcer of contiguous site of back, buttock and hip, unstageable (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.45 – Pressure ulcer of contiguous site of back, buttock and hip, unstageable
What it is
This code identifies a pressure ulcer affecting a combined area of the back, buttock, and hip that cannot be staged because the wound base is obscured. Use it when the documentation specifies this contiguous site and unstageable status.
Clinical signs
Typical findings include full-thickness tissue loss with the ulcer base covered by slough, eschar, or other nonviable tissue. Clinical features vary; refer to documentation for the exact appearance and extent.
When to use this code
Use L89.45 when the provider documents an unstageable pressure ulcer spanning the contiguous back, buttock, and hip region. It is appropriate when the wound cannot be staged because the depth is hidden. If the record names a different site or a stage, choose the more specific code.
Do not use for
Do not use this code for pressure injuries at a single anatomic site, such as only the sacrum or only the hip. Do not use it if the ulcer stage is documented and staging is possible.
Coding tip
Verify the exact location and whether the wound is truly unstageable before assigning L89.45.
