ICD-10 Code L89.513 – Pressure ulcer of right ankle, stage 3 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.513 – Pressure ulcer of right ankle, stage 3
What it is
This code identifies a pressure ulcer on the right ankle with full-thickness skin loss extending into subcutaneous tissue. Stage 3 means the wound is deeper than stage 2 but does not expose bone, tendon, or muscle.
Clinical signs
You may see a crater-like ulcer, visible subcutaneous fat, and slough or undermining. Clinical features vary; refer to documentation, especially for wound depth and whether bone or tendon is exposed.
When to use this code
Use L89.513 when the provider documents a stage 3 pressure ulcer specifically on the right ankle. The record should clearly support both the anatomic site and stage. If the site, laterality, or stage is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for stage 1, stage 2, unstageable, or deep tissue pressure injuries. Also avoid it when the ulcer is on a different ankle or another body site.
Coding tip
Match laterality and stage exactly to the provider’s wound documentation before coding.
