ICD-10 Code L89.139 – Pressure ulcer of right lower back, unspecified stage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.139 – Pressure ulcer of right lower back, unspecified stage
What it is
This code identifies a pressure ulcer located on the right lower back when the stage is not documented. Use it for a localized skin and tissue injury caused by sustained pressure in that area.
Clinical signs
Findings may include a persistent open sore, skin breakdown, or tissue loss over the right lower back. Clinical features vary; refer to documentation for the ulcer stage and depth.
When to use this code
Use this code when the record clearly states a pressure ulcer on the right lower back and does not specify the stage. It is also appropriate when the clinician documents the site but staging is unavailable. If later notes provide a stage, code to the documented stage instead.
Do not use for
Do not use this code for non-pressure skin wounds, abrasions, or surgical wounds. Do not use it when the ulcer stage is documented; check documentation and code the stated stage.
Coding tip
Verify both laterality and exact anatomic location before assigning this code.
