ICD-10 Code L89.142 – Pressure ulcer of left lower back, stage 2 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.142 – Pressure ulcer of left lower back, stage 2
What it is
This code identifies a pressure ulcer on the left lower back with stage 2 skin damage. Stage 2 means partial-thickness loss of skin, often appearing as a shallow open sore or blister.
Clinical signs
Look for localized skin loss involving the epidermis and possibly part of the dermis, with a pink or red wound bed. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a pressure injury on the left lower back and specifies stage 2. It also applies when the wound is described as partial-thickness skin loss in that location.
Make sure the site is clearly the left lower back, not the sacrum, buttock, or another back region. If the stage or exact location is unclear, check documentation before coding.
Do not use for
Do not use this code for unstageable ulcers, deep tissue injury, or stage 1 pressure injury. Do not use it if the wound is on a different body site.
Coding tip
Confirm both laterality and stage in the provider note before assigning L89.142.
