ICD-10 Code L89.301 – Pressure ulcer of unspecified buttock, stage 1 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.301 – Pressure ulcer of unspecified buttock, stage 1
What it is
This code identifies a pressure ulcer on the buttock when the side is not specified and the injury is stage 1. Stage 1 means intact skin with localized redness that does not blanch.
Clinical signs
You may see persistent erythema over the buttock, with skin still intact and no open wound. Clinical features vary; refer to documentation if staging is unclear or if skin changes are not described.
When to use this code
Use L89.301 when the record documents a pressure ulcer on the buttock, the laterality is not stated, and the stage is 1. It is appropriate for pressure-related skin injury with intact skin. If the note specifies a different stage or site, code that documented detail instead.
Do not use for
Do not use this code for non-pressure skin irritation, moisture-associated dermatitis, or ulcers at another anatomic site. Do not use it when the documentation names a different stage or provides a more specific buttock location.
Coding tip
Confirm both the stage and the exact site in the note before assigning this code.
