ICD-10 Code L89.95 – Pressure ulcer of unspecified site, unstageable (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.95 – Pressure ulcer of unspecified site, unstageable
What it is
This code identifies a pressure ulcer at an unspecified body site that cannot be staged because the wound base is obscured by slough, eschar, or other covering. Use it when documentation confirms unstageable pressure injury but does not name the location.
Clinical signs
Typical findings include an open or closed wound with tissue loss where the depth cannot be determined. Clinical features vary; refer to documentation for the site, appearance, and whether necrotic tissue or eschar is present.
When to use this code
Use L89.95 when the provider documents an unstageable pressure ulcer but does not specify the anatomic site. It also fits when the record describes a pressure injury with obscured wound bed and no stage can be assigned. Check documentation if the site is later clarified.
Do not use for
Do not use this code for a staged pressure ulcer with a known depth or for non-pressure wounds such as skin tears or surgical wounds. If the site is documented, choose the more specific pressure-ulcer code instead.
Coding tip
Query for the exact site whenever “unspecified” appears, because laterality and location can change the final code.
