ICD-10 Code L89.610 – Pressure ulcer of right heel, unstageable (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.610 – Pressure ulcer of right heel, unstageable
What it is
This code identifies a pressure ulcer located on the right heel that cannot be staged because the wound base is covered by slough or eschar. You use it when the depth of tissue loss is not visible.
Clinical signs
Typical findings include an ulcer on the right heel with full-thickness tissue loss obscured by necrotic tissue. Clinical features vary; refer to documentation.
When to use this code
Use L89.610 when the provider documents an unstageable pressure injury specifically on the right heel. The record should show that staging is not possible because the wound bed is covered. If the site, laterality, or stage is unclear, check documentation before coding.
Do not use for
Do not use this code for pressure ulcers on another heel or other body site. Do not use it when the ulcer stage is documented and visible, or when the lesion is not a pressure ulcer.
Coding tip
Verify right-sided laterality and unstageable status in the provider note before assigning L89.610.
