ICD-10 Code L89.143 – Pressure ulcer of left lower back, stage 3 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.143 – Pressure ulcer of left lower back, stage 3
What it is
This code identifies a stage 3 pressure ulcer on the left lower back. The wound extends through the full thickness of skin and involves deeper tissue, but not bone, tendon, or muscle.
Clinical signs
Expect a visible open ulcer with full-thickness skin loss and fat exposure. Clinical features vary; refer to documentation for depth, location, and staging details.
When to use this code
Use this code when the record clearly states a pressure ulcer on the left lower back and documents stage 3. You should confirm laterality and anatomic site match the note. If the stage is not specified, check documentation before coding.
Do not use for
Do not use it for stage 1, stage 2, unstageable, or deep tissue pressure injuries. Also avoid it when the ulcer is on a different site or when the chart does not support stage 3.
Coding tip
Always code the documented stage and exact location together, and query if either element is missing.
