ICD-10 Code L89.502 – Pressure ulcer of unspecified ankle, stage 2 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.502 – Pressure ulcer of unspecified ankle, stage 2
What it is
This code identifies a pressure ulcer on the ankle when the laterality is not specified and the ulcer is stage 2. Stage 2 means partial-thickness skin loss with exposed dermis, often appearing as a shallow open ulcer or blister.
Clinical signs
Look for a localized ankle pressure injury with loss of the epidermis and part of the dermis. Clinical features vary; refer to documentation for laterality, depth, and whether the wound is staged as 2.
When to use this code
Use L89.502 when the provider documents a pressure ulcer of the ankle, stage 2, and does not specify right or left. This is appropriate for inpatient, outpatient, or wound-care documentation when the diagnosis is clearly stated. If laterality is documented, choose the more specific code.
Do not use for
Do not use this code for a non-pressure wound, abrasion, or venous ulcer. Do not use it if the ulcer is documented as a different stage or if the ankle side is specified and another code is required.
Coding tip
Verify the pressure ulcer stage and laterality in the chart before assigning L89.502.
