ICD-10 Code L89.624 – Pressure ulcer of left heel, stage 4 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.624 – Pressure ulcer of left heel, stage 4
What it is
This code identifies a pressure ulcer on the left heel with full-thickness skin and tissue loss extending to deeper structures. Stage 4 ulcers may expose muscle, tendon, ligament, cartilage, or bone.
Clinical signs
Look for an open ulcer over the left heel with full-thickness tissue loss and visible or palpable deep structures. Clinical features vary; refer to documentation for depth, wound bed description, and any exposed tissue.
When to use this code
Use L89.624 when the provider documents a stage 4 pressure injury specifically on the left heel. It is appropriate when the record clearly states the stage and location. If the stage or laterality is unclear, check documentation before coding.
Do not use for
Do not use this code for pressure ulcers at another site, a different stage, or unstageable wounds. Do not use it when the chart only says “heel ulcer” without confirming a pressure injury.
Coding tip
Match the documented site and stage exactly, because heel laterality and ulcer stage drive code selection.
