2026 ICD-10-CM Diagnosis Code L89.511 – Pressure ulcer of right ankle, stage 1
What it is
This code identifies a pressure ulcer on the right ankle that is limited to intact skin with persistent redness. It means the tissue is threatened, but there is no open wound.
Clinical signs
Look for localized nonblanchable erythema over the right ankle, often with tenderness, warmth, or altered sensation. Clinical features vary; refer to documentation.
When to use this code
Use this code when documentation states a stage 1 pressure injury or pressure ulcer at the right ankle. It is appropriate when the skin remains intact and the site is clearly documented. If the stage or laterality is unclear, check documentation.
Do not use for
Do not use this code for nonpressure skin breakdown, abrasions, or ulcers at another site. Do not assign it if the ulcer is open or staged differently.
Coding tip
Confirm both laterality and stage in the note before coding.
