ICD-10 Code L89.122 – Pressure ulcer of left upper back, stage 2 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.122 – Pressure ulcer of left upper back, stage 2
What it is
This code identifies a stage 2 pressure ulcer located on the left upper back. Stage 2 means partial-thickness skin loss with exposed dermis, often appearing as a shallow open ulcer or blister.
Clinical signs
Typical findings include a shallow wound, intact or ruptured blister, or pink-red wound bed without slough. Clinical features vary; refer to documentation for exact staging and location.
When to use this code
Use L89.122 when the record clearly documents a pressure ulcer on the left upper back and specifies stage 2. You should also use it when the provider describes partial-thickness skin loss at that site. Check documentation if the stage, laterality, or location is unclear.
Do not use for
Do not use this code for deep tissue injury, unstageable pressure injury, or ulcers at another body site. If the wound is not documented as a pressure ulcer, choose the more accurate diagnosis.
Coding tip
Verify both the stage and exact anatomic location before assigning this code.
