ICD-10 Code L89.13 – Pressure ulcer of right lower back (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.13 – Pressure ulcer of right lower back
What it is
This code identifies a pressure ulcer located on the right lower back. Use it when documentation specifies the site and confirms a pressure injury, not another type of skin breakdown.
Clinical signs
Findings may include localized skin damage, redness, open ulceration, or deeper tissue loss over the right lower back. Clinical features vary; refer to documentation for stage and severity.
When to use this code
Use L89.13 when the provider documents a pressure ulcer on the right lower back and the location is clearly stated. It is appropriate for inpatient, outpatient, or wound-care records when the diagnosis is confirmed. If staging is also documented, code it separately as required.
Do not use for
Do not use this code for simple redness, moisture-associated skin damage, or an ulcer at a different site. Check documentation if the record does not clearly identify a pressure ulcer on the right lower back.
Coding tip
Verify both the pressure-ulcer diagnosis and the exact right lower back location before assigning L89.13.
