ICD-10 Code L89.312 – Pressure ulcer of right buttock, stage 2 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.312 – Pressure ulcer of right buttock, stage 2
What it is
This code identifies a pressure ulcer on the right buttock with partial-thickness skin loss. Stage 2 means the skin is open or blistered, but deeper tissue is not exposed.
Clinical signs
You may see a shallow open ulcer, a pink or red wound bed, or an intact or ruptured serum-filled blister. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a stage 2 pressure injury specifically on the right buttock. It applies when the ulcer is limited to partial-thickness skin loss and the laterality is clearly stated. If staging or location is unclear, check documentation.
Do not use for
Do not use this code for pressure ulcers at other buttock sites, deeper stage 3 or stage 4 ulcers, or unstageable lesions. If the record does not confirm stage 2, check documentation.
Coding tip
Confirm both laterality and stage in the provider note before assigning L89.312.
