ICD-10 Code L89.102 – Pressure ulcer of unspecified part of back, stage 2 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.102 – Pressure ulcer of unspecified part of back, stage 2
What it is
This code identifies a pressure ulcer on an unspecified area of the back with stage 2 skin loss. Stage 2 means partial-thickness skin damage, often presenting as a shallow open ulcer or blister.
Clinical signs
Look for partial-thickness skin breakdown involving the dermis, with a shallow red-pink wound bed or an intact/ruptured serum-filled blister. Clinical features vary; refer to documentation.
When to use this code
Use L89.102 when the provider documents a stage 2 pressure ulcer on the back but does not specify the exact back location. Code it only when the record supports pressure-related skin injury and stage 2 depth. If the site or stage is unclear, check documentation.
Do not use for
Do not use this code for stage 1, stage 3, stage 4, unstageable, or deep tissue pressure injuries. Do not assign it when the ulcer is on a different body site or when documentation does not confirm a pressure ulcer.
Coding tip
Verify both the stage and that the back site is unspecified before assigning L89.102.
