ICD-10 Code L89.50 – Pressure ulcer of unspecified ankle (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.50 – Pressure ulcer of unspecified ankle
What it is
This code identifies a pressure ulcer located at the ankle when the documentation does not specify the side or stage. Use it for a pressure injury caused by prolonged pressure over the ankle area.
Clinical signs
Findings may include localized skin breakdown, discoloration, pain, or an open wound over the ankle. Clinical features vary; refer to documentation for laterality, depth, and staging details.
When to use this code
Use L89.50 when the record clearly states a pressure ulcer of the ankle but does not identify whether it is right or left. It also applies when the ankle site is documented without a stage. If the chart includes a more specific site or stage, code that detail instead.
Do not use for
Do not use this code for non-pressure wounds, venous ulcers, or diabetic foot ulcers. Check documentation if the ulcer is on a specific ankle side or another nearby location.
Coding tip
Assign the most specific pressure ulcer code available, and verify laterality and stage before defaulting to unspecified ankle.
