ICD-10 Code L89.150 – Pressure ulcer of sacral region, unstageable (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.150 – Pressure ulcer of sacral region, unstageable
What it is
This code identifies a pressure ulcer over the sacral area whose true depth cannot be determined because the wound base is covered by slough or eschar. You should use it when staging is not possible from available documentation.
Clinical signs
Typical findings include a sacral wound with devitalized tissue obscuring the ulcer base. Clinical features vary; refer to documentation for whether the wound is fully covered by slough or eschar and cannot be staged.
When to use this code
Use L89.150 when the provider documents an unstageable pressure ulcer specifically in the sacral region. It is appropriate when the record states the wound cannot be staged because the base is not visible. If location or stage is unclear, check documentation before coding.
Do not use for
Do not use this code for a staged sacral pressure ulcer, a non-pressure wound, or a pressure injury at another site. If the documentation does not support sacral location or unstageable status, check documentation.
Coding tip
Confirm both the sacral location and the unstageable designation in the provider note before assigning this code.
