ICD-10 Code L89.000 – Pressure ulcer of unspecified elbow, unstageable (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.000 – Pressure ulcer of unspecified elbow, unstageable
What it is
This code identifies a pressure ulcer located on the elbow when the side is not specified and the wound cannot be staged because the base is covered by slough or eschar. Use it when documentation clearly states the ulcer is unstageable.
Clinical signs
Typical findings include an open pressure injury over the elbow with tissue loss and obscured wound depth. Clinical features vary; refer to documentation for evidence of slough, eschar, or other reasons staging cannot be determined.
When to use this code
Use L89.000 when the provider documents a pressure ulcer of the elbow, does not specify left or right, and states it is unstageable. It is appropriate when the wound cannot be staged because the base is not visible. Check documentation if laterality or stage is recorded elsewhere.
Do not use for
Do not use this code for a staged pressure ulcer, a pressure injury at a different site, or an elbow wound that is not documented as pressure-related. Check documentation if the laterality is known or if the ulcer is not unstageable.
Coding tip
Verify three elements in the note: pressure ulcer, elbow location, and unstageable status; then confirm that laterality is truly unspecified.
