ICD-10 Code L89.154 – Pressure ulcer of sacral region, stage 4 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.154 – Pressure ulcer of sacral region, stage 4
What it is
This code identifies a stage 4 pressure ulcer located over the sacral region. Stage 4 means full-thickness skin and tissue loss, with exposed deeper structures such as muscle, tendon, or bone.
Clinical signs
Look for a deep open wound in the sacral area with extensive tissue destruction. Clinical features vary; refer to documentation for exposed bone, undermining, tunneling, or necrotic tissue.
When to use this code
Use L89.154 when the provider documents a pressure ulcer of the sacrum specifically as stage 4. It is appropriate for inpatient, outpatient, or home health records when the site and stage are clearly stated. If stage or location is unclear, check documentation before coding.
Do not use for
Do not use this code for pressure injuries at other anatomic sites or for ulcers with an unspecified stage. Do not assign it if the record describes only skin breakdown without confirmation of stage 4.
Coding tip
Code the documented site and stage exactly; if either is missing, query the provider or review the record.
