ICD-10 Code L89.141 – Pressure ulcer of left lower back, stage 1 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.141 – Pressure ulcer of left lower back, stage 1
What it is
This code identifies a pressure ulcer on the left lower back at stage 1. The skin is intact, but the area shows persistent redness that does not blanch.
Clinical signs
Look for localized nonblanchable erythema over the left lower back, usually over a bony prominence. Clinical features vary; refer to documentation if the skin is intact but discolored or tender.
When to use this code
Use this code when the provider documents a stage 1 pressure injury specifically on the left lower back. It is appropriate when the site and stage are both clearly identified in the record. If laterality, location, or stage is unclear, check documentation.
Do not use for
Do not use it for open ulcers, suspected deep tissue injury, or pressure injuries at a different anatomic site. Do not assign it if the record does not support stage 1.
Coding tip
Code only when the note confirms both left-sided lower back location and stage 1 status.
