ICD-10 Code L89.506 – Pressure-induced deep tissue damage of unspecified ankle (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.506 – Pressure-induced deep tissue damage of unspecified ankle
What it is
This code identifies pressure-related deep tissue injury at the ankle when the exact side is not documented. It refers to damage from sustained pressure or shear over a bony area, with deeper tissue involvement than superficial skin redness.
Clinical signs
Typical findings include persistent discoloration, localized pain, and tissue firmness or bogginess over the ankle. Clinical features vary; refer to documentation for depth, laterality, and whether skin breakdown is present.
When to use this code
Use L89.506 when the record states deep tissue pressure injury or damage of the ankle and does not specify left or right. Apply it when the provider documents the ankle as the affected site and the lesion is pressure-induced. Check documentation if the note only describes redness, abrasion, or an ulcer without confirming deep tissue injury.
Do not use for
Do not use this code for pressure injuries at another site, or when the ankle laterality is documented. It is also not appropriate for non-pressure wounds, traumatic skin injury, or superficial pressure redness without deep tissue damage.
Coding tip
If laterality is missing, code the unspecified ankle only after confirming the injury is pressure-induced and specifically documented as deep tissue damage.
