ICD-10 Code L89.021 – Pressure ulcer of left elbow, stage 1 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.021 – Pressure ulcer of left elbow, stage 1
What it is
This code identifies a pressure ulcer on the left elbow at stage 1. Stage 1 means intact skin with localized nonblanchable redness over a pressure point.
Clinical signs
You may see persistent redness, warmth, or discoloration over the left elbow that does not blanch with pressure. Clinical features vary; refer to documentation.
When to use this code
Use L89.021 when the record clearly documents a stage 1 pressure ulcer on the left elbow. Code it when the provider specifies the site and stage, and the skin is intact but shows pressure-related erythema or discoloration. Check documentation if the stage is unclear.
Do not use for
Do not use this code for pressure injuries at another body site or for ulcers with a different stage. Do not use it when the documentation only says redness or skin breakdown without confirming a stage 1 pressure ulcer.
Coding tip
Verify both laterality and stage in the note before assigning L89.021.
