ICD-10 Code L89.313 – Pressure ulcer of right buttock, stage 3 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.313 – Pressure ulcer of right buttock, stage 3
What it is
This code identifies a pressure ulcer on the right buttock with full-thickness skin loss. Stage 3 means the ulcer extends into subcutaneous tissue but does not expose muscle, tendon, or bone.
Clinical signs
Expect an open ulcer with visible depth and slough or granulation tissue. Clinical features vary; refer to documentation for laterality, stage, and whether undermining or tunneling is present.
When to use this code
Use L89.313 when the provider documents a stage 3 pressure ulcer on the right buttock. The record should support both the anatomic site and the stage. If the stage is unclear or the site is different, check documentation before assigning this code.
Do not use for
Do not use this code for a stage 2, stage 4, unstageable, or deep tissue pressure injury. It also should not be used if the ulcer is on the left buttock or another body site.
Coding tip
Code the highest documented stage and confirm laterality from the provider note.
