ICD-10 Code L89.529 – Pressure ulcer of left ankle, unspecified stage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.529 – Pressure ulcer of left ankle, unspecified stage
What it is
This code identifies a pressure ulcer located on the left ankle when the stage is not documented. Use it when the record confirms a pressure injury at that site, but the depth or stage is unclear or not stated.
Clinical signs
Clinical features vary; refer to documentation. A pressure ulcer may show localized skin breakdown, discoloration, or tissue loss over a bony prominence such as the ankle.
When to use this code
Use L89.529 when the provider documents a pressure ulcer of the left ankle and does not specify the stage. It also fits when staging cannot be determined from the available record. If later documentation adds a stage, code the more specific staged ulcer instead.
Do not use for
Do not use this code for a non-pressure wound, diabetic ulcer, or venous stasis ulcer. Do not use it if the stage is documented and another more specific pressure ulcer code applies.
Coding tip
Check the note for laterality and stage before assigning this unspecified-stage code.
