ICD-10 Code L89.814 – Pressure ulcer of head, stage 4 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.814 – Pressure ulcer of head, stage 4
What it is
This code identifies a pressure ulcer on the head with full-thickness skin and tissue loss, stage 4. The wound extends into deeper structures and may expose muscle, bone, or supporting tissue.
Clinical signs
Stage 4 pressure ulcers usually show deep tissue destruction, undermining, or tunneling. Clinical features vary; refer to documentation for exact depth and any exposed structures.
When to use this code
Use L89.814 when the provider documents a pressure ulcer of the head and clearly states stage 4. Apply it for advanced decubitus wounds at this site, whether the note describes exposed bone or other deep tissue involvement. If staging is unclear, check documentation before coding.
Do not use for
Do not use this code for pressure injuries at other anatomical sites or for ulcers with a different stage. Do not assign it when the record only says “pressure ulcer” without confirming stage 4.
Coding tip
Match the site and stage exactly in the provider note; if either is missing, query before assigning L89.814.
