ICD-10 Code L89.601 – Pressure ulcer of unspecified heel, stage 1 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.601 – Pressure ulcer of unspecified heel, stage 1
What it is
This code identifies a pressure injury on the heel with intact skin and early localized damage. Stage 1 means the area is nonblanchable redness over a bony prominence.
Clinical signs
Look for persistent redness that does not turn white when pressed, with skin still intact. The heel may feel warmer, firmer, or more painful than nearby tissue; check documentation.
When to use this code
Use this code when the record documents a stage 1 pressure ulcer on an unspecified heel and no more specific heel laterality is given. It fits initial recognition of early pressure damage before skin breakdown occurs. If the provider names a different stage or location, code that documented finding instead.
Do not use for
Do not use this code for open wounds, blisters, or pressure ulcers with skin loss, because those imply a higher stage. Do not use it when the chart specifies the left or right heel.
Coding tip
Confirm both the stage and the heel laterality in the provider note before assigning L89.601.
