ICD-10 Code L89.314 – Pressure ulcer of right buttock, stage 4 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.314 – Pressure ulcer of right buttock, stage 4
What it is
This code identifies a stage 4 pressure ulcer on the right buttock. Stage 4 means full-thickness skin and tissue loss, with exposed deeper structures such as muscle, tendon, or bone.
Clinical signs
You may see an open ulcer with deep tissue destruction, undermining, or tunneling. Clinical features vary; refer to documentation for the exact stage and whether bone, muscle, or other structures are exposed.
When to use this code
Use this code when the provider documents a pressure ulcer specifically on the right buttock and classifies it as stage 4. It is appropriate when the record clearly identifies the site and stage. If the stage is not documented, or the ulcer is on a different buttock, check documentation.
Do not use for
Do not use this code for unstageable pressure injuries, suspected deep tissue injury, or ulcers on the left buttock or another location. Do not assign it if the stage or laterality is unclear.
Coding tip
Confirm both laterality and stage in the chart before coding, because pressure ulcer codes are site- and stage-specific.
