ICD-10 Code L89.004 – Pressure ulcer of unspecified elbow, stage 4 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.004 – Pressure ulcer of unspecified elbow, stage 4
What it is
This code identifies a stage 4 pressure ulcer on the elbow when the laterality is not specified. Stage 4 means full-thickness tissue loss, with exposed deeper structures such as muscle, tendon, or bone.
Clinical signs
Look for an open ulcer over the elbow with full-thickness skin loss and visible deeper tissue. Clinical features vary; refer to documentation for laterality, depth, and any exposed bone or other structures.
When to use this code
Use L89.004 when the provider documents a stage 4 pressure ulcer of the elbow but does not specify whether it is right or left. It also fits when the record clearly supports a pressure injury at that site with full-thickness loss. If the stage or location is unclear, check documentation.
Do not use for
Do not use this code for ulcers at other anatomic sites or for pressure injuries with a different stage. Do not use it when the elbow laterality is documented and a more specific code is available.
Coding tip
Verify both the stage and the exact elbow laterality in the chart before selecting this unspecified code.
