ICD-10 Code L89.894 – Pressure ulcer of other site, stage 4 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.894 – Pressure ulcer of other site, stage 4
What it is
This code identifies a pressure ulcer at a site other than the standard sacral, heel, hip, or ankle locations, with full-thickness skin and tissue loss. Stage 4 means exposed bone, tendon, or muscle may be present.
Clinical signs
Look for a deep ulcer with severe tissue loss and visible or palpable supporting structures. Clinical features vary; refer to documentation, but stage 4 commonly indicates advanced breakdown and possible undermining or tunneling.
When to use this code
Use L89.894 when the provider documents a pressure ulcer at another specified site and clearly states stage 4. You should code the documented site and stage together when both are supported. If the site is not specified, check documentation.
Do not use for
Do not use this code for unstageable pressure ulcers, suspected deep tissue injury, or ulcers from non-pressure causes. It also should not be used when the record documents a different stage.
Coding tip
Confirm both the exact site and stage in the note before assigning L89.894.
