ICD-10 Code L89.10 – Pressure ulcer of unspecified part of back (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.10 – Pressure ulcer of unspecified part of back
What it is
This code identifies a pressure ulcer located on the back when the exact site is not documented. Use it when the record confirms a pressure injury on the back but does not specify a more precise area.
Clinical signs
Findings may include localized skin breakdown, redness, open ulceration, or tissue loss over the back. Clinical features vary; refer to documentation for stage and depth.
When to use this code
Use L89.10 when the clinician documents a pressure ulcer of the back without naming the upper, lower, or other specific back region. It is also appropriate when the note confirms location on the back but does not provide enough detail for a more specific pressure ulcer code. Check documentation if staging or laterality is unclear.
Do not use for
Do not use this code for ulcers caused by venous disease, diabetes, trauma, or infection. Do not use it when the back site is specified more precisely in the record.
Coding tip
Query for the exact back location and pressure ulcer stage before coding if the documentation is incomplete.
