ICD-10 Code L89.113 – Pressure ulcer of right upper back, stage 3 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.113 – Pressure ulcer of right upper back, stage 3
What it is
This code identifies a pressure ulcer on the right upper back with full-thickness skin loss. Stage 3 means the ulcer extends into the subcutaneous tissue, but bone, tendon, and muscle are not exposed.
Clinical signs
Look for an open ulcer with visible depth and slough or granulation tissue in the wound bed. Clinical features vary; refer to documentation for laterality, location, and stage.
When to use this code
Use L89.113 when the provider documents a stage 3 pressure ulcer specifically on the right upper back. The record should support both the anatomic site and the stage. If the site is described differently or the stage is not confirmed, check documentation before coding.
Do not use for
Do not use this code for stage 1, stage 2, unstageable, or deep tissue pressure injuries. Also avoid it if the ulcer is on a different body site or the documentation does not specify the right upper back.
Coding tip
Match the stage and exact location in the provider note before assigning L89.113.
