ICD-10 Code L89.12 – Pressure ulcer of left upper back (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.12 – Pressure ulcer of left upper back
What it is
This code identifies a pressure ulcer located on the left upper back. Use it when documentation specifies a pressure injury in that exact anatomic site.
Clinical signs
Typical findings include localized skin breakdown over the left upper back, with possible redness, open ulceration, or deeper tissue loss. Clinical features vary; refer to documentation.
When to use this code
Use L89.12 when the provider documents a pressure ulcer on the left upper back and no more specific stage or depth code is available. It is appropriate for inpatient, outpatient, or wound-care records when the site is clearly stated. If staging is documented, code the stage as directed by the record.
Do not use for
Do not use this code for non-pressure skin ulcers, traumatic wounds, or ulcers on another back location. Check documentation if the pressure injury site is unclear.
Coding tip
Verify both laterality and exact location before assigning the code.
