ICD-10 Code L89.526 – Pressure-induced deep tissue damage of left ankle (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.526 – Pressure-induced deep tissue damage of left ankle
What it is
This code identifies a pressure-related injury affecting deep tissue over the left ankle. It is used when the skin may be intact, but underlying tissue damage is present from sustained pressure or shear.
Clinical signs
Typical findings include localized discoloration, pain, bogginess, or a deep purple or maroon area over the left ankle. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record documents deep tissue pressure damage specifically at the left ankle. It fits pressure injuries described as deep tissue injury, suspected deep tissue injury, or similar wording when the left ankle is the documented site.
Apply it only when the provider links the lesion to pressure or shear and identifies the left ankle as the location. Check documentation if laterality, stage, or site is unclear.
Do not use for
Do not use this code for ulcers, abrasions, burns, or skin tears that are not pressure-related. Do not assign it if the documentation names a different site or does not confirm deep tissue damage.
Coding tip
Verify both the pressure-injury type and the left ankle location in the note before assigning L89.526.
